To lead the trend of digital single-lens reflex Canon EOS 7D Release
A new generation of digital SLR cameras, EOS 7D achieved in about 18 million effective pixel high-definition, under, up to about 8 / second continuous shooting speed. And the wisdom of carrying high-speed auto-focusing system, and many other new features. EOS 7D is owned by high-performance Canon has long been dependent on a variety of core technology research and development. These high-end technology merges with each other so that the performance upgrades, functionality and ease of use reached a high degree of integration. Next, let’s side of the attention to these techniques, the side through the EOS 7D of the seven pairs of performance to explore its advantages. EOS 7D listing dates are expected by the end of September 2009.
One of seven pairs of about 18 million effective pixel + ISO 12800 and the highest point of the double-effect low-noise high-quality high-pixel image sensor and can demonstrate a more sophisticated image. EOS 7D can be shown with the visual impact of the image, it is because of its approximately 18 million effective pixel APS-C size CMOS image sensors. With the development of semiconductor technology and image processing technology advances, EOS 7D not only reached about 18 million effective pixel, but also achieved a low noise performance of the fine image. Its onboard CMOS image sensor is a Canon developed its own products. CMOS wafer process into a more sophisticated production process, not only solved the cause of the high pixel area of each pixel to narrow the problem, but also uses a higher photoelectric conversion efficiency of the new photodiode. In improving the pixel sensitivity at the same time, the transistors within a pixel was modified to achieve a higher S / N (signal to noise) ratio. In order to effectively improve the condensing rate, in addition to using non-gap micro-lens technology, also used to reduce the micro-lens to the photodiode from the new technologies, successful beyond the rate of the previous condenser. EOS 7D commonly used ISO sensitivity of 100-6400, extended ISO sensitivity up to 12800. Image signal transmission is the sequence of the single-channel high-speed reading, while in 8-channel high-speed reading. Compared with the EOS 50D is about 1.3 times faster to achieve about 8 / s high-speed continuous shooting. Low-voltage power supply of high-speed amplifiers and a variety of energy-saving measures adopted to achieve the low power consumption. In addition, replacement of lens and mirror, shutter and other movements generated when the dust sensor also used the corresponding integrated dust removal measures; while carrying from the camera hardware and software, two aspects with dust of the “EOS Integrated Cleaning System “in the dust function very thoughtful consideration. Shutter unit and a body covered with debris could not easily produce the special material; even accidentally into the dust, you can also make the image by using ultrasonic sensors in front, low-pass filter to vibrate and shake off the dust. Low-pass filter made of fluorine coating the surface, be it hard to shed the dust that has a high viscosity or a damp dust all have a very good dust effects.
7 pairs of the two DIGIC 4 + DIGIC 4 image processor, dual-digit achieve 8 / s DIGIC 4 pairs of high-speed continuous shooting of digital imaging processors to achieve through the eight-channel high-speed from the image sensor to read out, with about 18 million pixel a large information quickly and precision handling. Carrying two high-performance digital image processor, DIGIC 4, capable of a variety of data parallel processing, even an effective plan of about 18 million yuan can be achieved up to about 8 / s burst of high-speed image processing. Capture images of the analog-digital conversion are 14-bit (16384 colors) for, even if high-speed in-camera processing analog-digital conversion will not reduce the number of bits. EOS 7D is not only equipped with a dual DIGIC 4, and equipped with two newly developed to convert analog signals to digital signals, high-speed 4-channel analog-digital conversion front-end modules, and dual DIGIC 4 combinations of high-speed parallel processing circuits. Based on these technologies, not only to achieve high-speed processing of image data will be used ISO sensitivity up to 6400, and maintain low noise image effects. In addition the effect of automatic optimization of brightness is also further enhanced. The amount of light surrounding the lens correction, processing is completely able to adapt to primitive and shooting speeds are improved.If you use compatible with UDMA (Ultra Direct Memory Access) memory cards, then store the image data can also be high-speed. EOS 7D color style through “Picture Style” to achieve. In addition to the default camera 6 (Standard, Portrait, etc.), the Canon is also based on the user need to provide a 7 “Picture Style Files” (nostalgia, dawn and dusk, etc.), a total of 13 kinds of photo styles. Moreover, the user can also style on top of an existing photo to fine-tune handling. In addition, users can use the camera with the software “Picture Style Editor”, to produce their own original Picture Style file. Preset white balance can be carried out from 9 kinds of choices, and depending on the shooting of its intent to fine-tune. EOS 7D is the ability to plan for about 18 million yuan, up to about 8 / second continuous shooting speed, to conduct high-speed image processing of these complex models. Which is precisely to provide protection for these new dual DIGIC 4 Digital Image Processor.
7 pairs of the three central F2.8 + F5.6 8 to the double cross, all 19 points cross-type AF system for high-resolution digital SLR cameras, the ability to accurately capture the various scenarios of Pi Sheti high-performance auto-focus system is even more important. EOS 7D carrying as many as 19 of the automatic focus, and to increase the focus of each of the focus accuracy. 19 pairs of focus corresponding to F5.6 beam used in all cross-type AF sensors. Will be used to detect vertical lines of horizontal linear AF sensor used to detect horizontal lines with vertical linear AF sensor was cross-shaped arrangement, thereby achieving a high Pi Sheti capture capabilities. Central focus is on relative to F5.6-beam cross-type AF sensors, the direction of the ramp to configure the corresponding F2.8 beam more accurate cross-type AF sensors. Through the central 8 to the double cross AF sensors work together to achieve high-speed and high precision co-coke. Tracking Pishe Ti AI Servo AF feature on the EOS 7D also been a substantial evolution. Beishe Ti is not only a tracking camera and the distance, in the Pi Sheti relatively parallel to the camera for vertical or horizontal movement of the scenes, it is also able to automatically switch the focus to the track (19 points AF pm). Moreover, the focus will also be displayed automatically track the situation, so you can be assured through the viewfinder of the Pi Sheti track. In the EOS 7D, the automatic focus selection methods and systems have also been a substantial evolution. In the original manually select one point of the “single-point auto-focus,” based on the increase in the “fixed-point auto-focus”, “automatically expand the focus.”Fixed-Point Auto Focus AF range than single-point AF smaller, more precise co-coke. Automatic focus of expansion is that, when the Pi Sheti deviate from the manual of choice due to movement of the focus, it will automatically start the selected adjacent pairs of auto-focus focus focus to support. In addition, EOS 7D also has a “regional auto-focus”, which is the 19 auto-focus is divided into five regions of the user can select any one of focus from one area to focus. Not only that, can simultaneously use of all 19 AF points “automatic select: 19 points Auto Focus,” has also been strengthened. Whether in the aspects of the camera’s high-definition or high-speed aspects of the implementation of appropriate countermeasures. It is the support of their newly developed AF sensor and the corresponding calculation engine. AF sensor unit in the optical auto-focus on the accuracy is enhanced. Structure using durable construction and materials. For the AF-related information processing, to take specific processor and the camera auto-focus with the central processing unit distributed processing approach, providing a fast and accurate auto-focus.
7 pairs of the four used vision rate of 100%, 100% of the dual-magnification optical viewfinder 100% of
EOS 7D optical viewfinder apparatus the rate of about 100% of the vision about a fold (100%) magnification at the same time with a 29.4 ° viewing angle and 22 mm eye point, the optical properties of the ancient EOS single-lens reflex camera also in the forefront . Vision rate of about 100 percent through the optical viewfinder observed range and scope of the actual shooting are basically the same, it can be very precise composition. The viewfinder is about 1-fold (100%) magnification with the optical performance beyond the professional models. Together with about 29.4 ° wide viewing angle, can be observed with the professional EOS-1D Mark III model basically the same size of the viewfinder image, to enjoy the fun of shooting. Because it is 22mm high eye point, so even if wearing glasses and rarely appears viewfinder viewfinder image is blocking the view of the situation so that the whole viewfinder image at a glance. In order to achieve the desired optical properties, EOS 7D uses the EOS-1D Mark III with the same size pentaprism. Meanwhile, in order for large pentaprism caused by chromatic aberration to compensate for eyepiece used with a high refractive index glass.These are to maintain the quality of the efforts made by the camera. In addition, EOS 7D inside the optical viewfinder is also equipped with a transparent liquid crystal panel with the back of “the wisdom of optical viewfinder for Information Display,” which can be displayed on the grid focusing screen and three-dimensional electronic level and so on. Back penetrating liquid crystal panels used in new materials PNLCD (Polymer Network LCD) is a watch also has the use of display materials, this material a strong candidate as an electronic paper has been widespread concern. Under normal circumstances, the viewfinder LCD panel equipped with transparent back, after the internal amount of light will fall, but the EOS 7D injection through the prism surface and fired five had anti-reflective surface coating and other processing, to ensure that its shooting device brightness and did not carry back the time of penetration-type LCD panel brightness of the same. This will not only clear way to watch the viewfinder image, operate also brings convenience. Using the optical viewfinder when shooting, three-dimensional electronic level by automatically focus the camera flashes to show the level of vertical and tilt around the state. Even in the eye without leaving the viewfinder cases, a confirmation screen immediately before and after the standard vertical and inclined state of the hand-held camera is very convenient feature.
7 pairs of the five test brightness + color and automatically focus on the information layer 63 area metering sensor
EOS 7D’s “63 area metering sensor layer” can quickly respond to changes brought about by Pi Sheti scene brightness and color changes and considered in the development of fully automatic focus with 19 of the linkage. Use of new sensors iFCL wisdom of a comprehensive metering system, not simply the brightness of the Pi Sheti detection, also Pishe Ti colors, and types of light sources are also calculated. And to consider from 19 auto-focus to be focusing on information, so that various scenarios can be suitable for metering. iFCL smart metering system is integrated i = intelligent (smart), F = Focus (AF information), C = Color (color information), L = Luminance (brightness information) English acronym as a way to demonstrate its advanced nature . Metering sensor by detecting the color information, you can easily make the original red line appears underexposed Beishe Ti becomes bright and vivid, to get closer to the natural effect of the human eye can see. In addition, because the screen throughout the 63 district and 19 AF points corresponding to a region, so the information from the auto-focus can be locked in the main Pi Sheti the size of the screen and places, thus can lose focus volume to determine the exposure value. Region through the use of 63 metering E-TTL II metering function is also to be evolved. In this way, the flexibility to use the camera distance information to complete a more accurate auto-exposure shooting. EOS 7D exposure compensation range has been significantly improved to achieve a ± 5 level, can more easily achieve the effect of a stronger effect of high-profile or low-key performance. Against night or when shooting buildings, etc., such as screen brightness contrast, there can be consciously shoot more than one underexposed and overexposed photos, through the synthesis of a computer for processing, which means it makes shooting HDR (high dynamic range) and so the material has become more convenient. Using different exposure values automatically Continuous shooting multiple photos of the AEB (auto exposure bracketing) settings range has also been expanded.
7 pairs of the six pairs of shape and sound and body design
EOS 7D’s body shape by using a continuous spherical surface of the ultra-streamlined design of plastic. Fuselage shell using light weight, high rigidity and electromagnetic shielding effect of magnesium alloys. Surface coating used with the EOS digital SLR camera EOS-1D series of top-coating materials and processes the same. In addition, EOS 7D also has a water droplet dust structure, magnesium alloy external components into a high-precision joints construction, battery storage, memory card slot cover, as well as operation buttons and so on around the sealing components used to protect the camera’s internal. Designed to take into account the body can increase the satisfaction of the owner of the design and make a good body shot more reassuring solidity. The shutter button is used with the EOS-1D series of the same type of buttons. Half-press the shutter button and press the shutter button completely different, operate handy. EOS 7D comparable to professional-grade camera with waterproof performance drops dust. In addition, as the main structure of the internal, EOS 7D has a rigid stainless steel frame and high-strength engineering plastics made of mirror box. One inside and outside the fuselage structure to improve the strength of the camera. EOS 7D inherits the EOS 5D Mark II’s basic structure, using a durability test more than 150,000 times the shutter unit. Shutter unit using non-contact magnetic levitation method to remove the physical contact area, well suppressed by the adsorption of dust and grease caused by fault movements, as well as lower accuracy. In addition, EOS 7D also used to bounce right moment the main reflector and sub-mirror to mirror the newly developed braking braking bodies, so that the stability of high-speed continuous shooting action. To AI Servo AF functions to more high-precision auto-focus at the same time, inhibit mirror components is a crash, guaranteed to produce crisp, neat, with a metallic shutter sound. In this way, not only the appearance, sound also is very careful, in the sense of touch and hearing, both given full consideration.

Focusing System Introduction
【Central 8 to double cross, all 19 points cross-type AF system enables detection of complex Pishe Ti】
EOS 7D equipped with a 19 automatic focus, its used in all cross-type sensors. The so-called cross-type sensor is the will of the vertical lines and horizontal lines tested showed cross-type sensors arranged. This is a less suffer an Beishe Ti shape and texture affect the resulting failure of co-focus system. Since these are used for the focus of the corresponding F5.6 beam sensor, therefore, can not install the camera with the lens aperture size on the impact of all the EF lens focal performance are to be combined into full play. In addition, the central upper, middle and lower three horizontal lines detection sensor showed two staggered by a double test to reduce testing errors. Substantially de-coke (large nominal) state, was arranged in two staggered AF sensors together to improve the detection rate of Pi Sheti. Moreover, the use of a higher frequency of central focus, in addition to the corresponding F5.6 was cross beam sensor arrangement, the configuration is still in its diagonal direction of the corresponding F2.8 beam cross-type sensors, which constitute the central 8 to the double cross AF sensors, capable of more precise focus. F2.8 large amplitude beam ratio F5.6 beam to detect the use of the baseline length is longer, with the ability to detect subtle errors combined ability to focus. EOS 7D equipped with a light color to be able to detect 63 district metering double-sensor autofocus system with photometric detection sensor data caused by different light sources combined focus error compensation. High-performance auto-focusing system can fully play up to about 18 million effective pixel strength, allowing users to shoot even more confidence. To be able to play a stable performance of autofocus, auto-focus optical system is also a corresponding increase in accuracy, but also adopted a strong ability to adapt to harsh environment, the construction and materials.
【Using 19 AF points focus on the five kinds of automatic selection mode】
EOS 7D equipped with a central 8 to the double cross, all 19 points cross-type AF sensors, to enable the effective use of this auto-focus, Canon provides the user with five kinds of automatic focus selection mode. Manual selection mode, in addition to include a “single point of focus”, but also has a focus range than single-point AF Focus range of smaller “fixed-point auto-focus,” and when Pi Sheti automatically from the selected focus, the selected focus point around the upper and lower pairs of secondary focus will automatically focus the “automatic extension of the focus” and a wealth of auto-focus area selection mode. In addition, the “area AF” will be 19 pairs were divided into five focus areas, from which you can select the focus area, focus will be to use the selected AF area focus on the Pi Sheti all right to detection. Priority so that composition, while Pi Sheti can accurately capture. In addition, the “19-point AF” also be able to use the central 8 to the double cross, all 19 points cross-type AF sensors of the Pi Sheti capture, increased its capacity to respond to irregular movement Pishe Ti.
【Have evolved, the ability to capture more of the AI Servo AF】
Able to track moving objects in AI Servo AF has been a substantial evolution. Be able to correspond through a variety of sports and shooting scenes of new AI Servo AF algorithm to achieve high-precision focus on moving objects. Not only the distance between the targeted and Pishe Ti, but also be able to select “19-point AF” or “regional auto-focus”, the right frame (auto-focus area, the use of area AF for the selection of within the region) vertical and horizontal direction parallel to track the movement of Pi Sheti and can be carried out continuously on the Pi Sheti capture. In addition, the ability to set AI Servo AF automatically starts when the focal point, thereby reducing filming the first one, the co-focus position deviation probability. In the “19-point autofocus” mode, when Pi Sheti’s movement did not automatically selected from the initial focus, other auto-focus will be on the track it automatically. At the same time, the current track of the Pi Sheti automatic right focus will be displayed in the viewfinder, the significantly increased peace of mind when shooting a sense of dynamic objects.
【To more carefully reflect the intention of the photographer AF area selection mode】
With the auto focus system, multiple functions, the various settings are also projects a more detailed evolution. Can be horizontal or vertical grip for the camera were set AF area selection mode and the use of auto-focus (regional) position. To use this feature, even if holding machine to change direction, without having to re-set the auto-focus area, with changing the direction of holding machine immediately after the filming of Pishe Ti and many other advantages. Held in the vertical plane, can differ from those used according to the user (or a handle in the next), were set. In addition, you can also customize the control buttons, respectively, of the four kinds of auto-focus-related functions (select AF area selection mode, AI Servo tracking sensitivity, AI Servo 1 / 2 images priority, AI Servo Focus Tracking mode) to register. After registration, you can also push-button operation (depth of field preview button or the lens AF stop button) when shooting a button quickly to set a good tone out these functions. EOS 7D like this can have a demand in the interim to change when necessary to set autofocus features, making it ideal for sports such as changes in intense sports photography.Moreover, EOS 7D also features the “auto-focus fine-tuning,” “can not be auto-focus lenses when driving,” and many other AF-related with custom features, can be more delicate reflect the photographer’s intentions.
Dual DIGIC 4, long shutter life
Dual DIGIC 4 to about 18 million effective pixel image data processing diagram of an effective plan of about 18 million yuan of the image sensor through the eight channels can quickly send a large image data, using two high-speed analog signal can be converted to digital signals of new development of four-channel analog-digital conversion front-end processing module. Through a combination of dual DIGIC 4 achieved EOS 7D, high-speed parallel processing. Its overwhelming high-speed processing capability, bringing about 18 million effective pixel, the maximum of about 8 / s high-speed continuous shooting speed. High-speed processing circuit design makes the EOS 7D even after 14-bit analog-digital conversion processing, the burst speed does not change, while achieving high quality and high reactivity, which is a major feature of it. Canon color style, which introduces its own development of “photo-style.” Be able to shoot scenes and themes according to the different selection, camera pre-loaded with six kinds of photo styles for users to choose and can be set up through detailed pictures of each style, sharpness and color and so on set. Not only that, but also can be attached to “Picture Style Editor” software production, register your own Picture Style can appreciate the performance of a variety of colors. Images within the camera compensate for the “automatic brightness optimization” feature has been enhanced, regardless of whether the screen to detect facial figure, the effect is more in place, and can inhibit the high light of high-light spillover “high-light tone priority” and able to prevent caused by different lens characteristics of the screen to reduce the amount of light surrounding the phenomenon of “peripheral light quantity correction” and other features are also due to the adoption of dual DIGIC 4 to achieve a high-speed processing.
The more you use the more fascinating, with a maximum of about 8 / s, 15 million times the life of the shutter unit
EOS 7D uses a newly developed non-contact electromagnetic rotary speed electronically controlled mechanical focal plane shutter, and its basic structure inherited the EOS 5D Mark II has been successfully applied on the shutter unit. And use with the EOS-1D series of the same material, reaching about 15 million times a shutter life. Non-contact rotary solenoid shutter unit has no physical contact with the unique surface structure, with a less there because of dust, oil and were attached to, or wear down causing malfunction and accuracy advantages. EOS 7D also has a mirror brake bodies, can guarantee high-speed continuous shooting, the AI Servo AF movements and the stability of the image within the viewfinder. Suspended motor enables quiet of shooting. EOS 7D carrying out a variety of advanced control of the shutter unit also very particular about the sound moves through the material of the shutter unit repeated studies, and a new brake master mirror the adoption of such agencies to achieve the right tone mirror drive when the motion control , has finally been able to inspire enthusiasm for shooting a “neat, crisp texture with a metal shutter sound.” Not only in function, the use of a sense of elegant, high-endurance shutter unit is really more you use the more fascinating.
The newly developed approximately 18 million effective pixel image sensor to achieve a high pixel low-noise point

To the corresponding standards and the direction of tilt before and after the three-dimensional electronic level
EOS 7D is the first EOS digital SLR camera equipped with a camera that can detect the standard and tilt before and after the “Three-dimensional electronic level” camera. Inside the camera perpendicular to the direction of optical axis configured two cameras were used to detect the level of tilt and acceleration before and after the tilt sensors. With minimum 1 ° as a unit, tilted in various directions for testing. Three-dimensional electronic level there are two kinds of display in the use of optical viewfinder for shooting to make use of automatic focus on the level of the direction of ± 6 °, front and rear direction of ± 4 ° tilt to display (camera horizontal shooting). Can also use the back of LCD monitors to display (real-time display photography, video shooting and shooting readiness pm). This displays a graphical water level, can the standard of the direction of 360 °, front and rear direction of ± 10 ° of tilt testing. With the normal function of the different electronic levels, which can tilt the direction of the camera before and after testing, with the screen even when there are no lines as a reference point, it is very easy to support the deformation of buildings and other adjustments to benefits.
To stabilize the double exposure of 63 area metering sensor
EOS 7D equipped with a 19 to take advantage of automatic focus-focus information, double-layer structure Metering Sensor – 63 area metering sensor layer. In addition to carry out the same as the previous evaluation of photometric sensors, metering, partial metering, spot metering (central point), the central focus of the average metering, to gain a more accurate exposure, the metering sensor also has the detection of RGB three primary colors R and B wavelength wavelength of color measurement features, and according to available information correctly to improve the red Pishe Ti prone to the phenomenon of lack of exposure. In addition, the 19 AF points correspond to a corresponding metering area, so you can refer to each of the focus in the brightness distribution and other means to lose focus and then calculate the amount of exposure value. Even in bright scenes are great differences, also get a smaller deviation of the stability of the information. Because the amount of exposure compensation extended to ± 5EV, so in a variety of auto-exposure modes are more handy.
LCD screen and the fuselage Introduction
Clearly show LCD Monitor II-type structure diagram is not only a real-time display shooting, video shooting capabilities enrich the digital SLR camera on the back also makes LCD monitors becoming increasingly important. Canon will be on the back of LCD monitors as key devices into a new technology. EOS 7D has a 160 ° wide viewing angle, and 92 million points of high-precision, “3.0″ clear display LCD Monitor II-type. “LCD Monitor-II clearly show the use of optical elastic material for the replacement of the original protective layer LCD monitor and LCD panel gap between the (air layer), which resolved by the protective layer and air layers of different refractive index caused by the external light reflection problems. As a result, the next day’s outdoor shooting screen LCD monitor is becoming clearer. In addition, beside the LCD monitor installed light sensors that can automatically adjust brightness with the surrounding brightness LCD monitor.
In the back of the LCD monitor performance at the same time, real-time display film / video shooting functions are to be upgraded. EOS 7D to add a dedicated start button, not only that, in real-time display film / video camera mode press the speed-control button can easily set up automatic brightness optimization, and quality / video record size; the fast mode in the AF Next, press the speed control buttons can be set to automatically focus position and auto-focus area selection mode.Moreover, the addition of menu displays real-time shooting / video capture functions tab (shot 4), a detailed menu, change the setting can not quit shooting directly. Similarly, immediate indication of the start auto focus under the shoot, regardless of AF-ON button or by pressing the shutter button is all OK. Video capture features in full HD (1920 × 1080) can choose to 30/25/24 frames per second frame rate, HD (1280 × 720) and SD (640 × 480) can select a more fluid per 60 / 50 of the frame rate. Video recording mode can use an external microphone. Not only can experience immersive sound effects (sampling frequency: 48KHz), and because the microphone can be away from the camera, so the camera movements recorded voice will not be able to get a clear recording. In addition, the video shot using the manual mode, can have full use of the image sensors of digital SLR camera features a large, greatly expanded its depth of field control, image expression.
EOS 7D house equipped with a video camera editing functions, even in the shooting scene, no computer around, you can also right before and after the cut scene editing, you can also enjoy the slideshow of all 5-second video playback. Compatible device because the connection can use HDMI terminals, so be able to enjoy to enjoy high-definition brings the fun.
Both functionality and operability of the ultra-sleek body design
EOS 7D will design and modeling functions also as a part of it. Followed the traditional design of the EOS but also the pursuit of beauty and ease of use, eventually forming a “super-sleek” design. In particular the shape of the camera at the top of a continuous smooth surface is formed, the handle with ergonomic principles for a new design. Special attention was paid when the finger hook grip force handle the situation. Some details are also made great efforts, such as changing the decorative parts of the surface of the fuselage skin thickness. Body on the back part of the stress-speed control dial and hand-held nature of the operation of a sense of the overall design uses a single hand to bring the camera reduces the burden on the shape of the hand. The camera itself is small and lightweight, shell using electromagnetic shielding function of magnesium alloys. The adoption of sealing parts departments as well as decorative skin tight structure so that the camera has a better performance of water droplets dust. There is to take with the EOS-1D series of the same coating process, you can minimize the wear surface of the fuselage. The bottom of the camera tripod equipped with a rubber around the next hole, so that when you install PTZ stability can be improved. The button in the functionality to upgrade the same time, mainly related to the operation buttons on the LCD monitor on the left; button on the key-way deeper, operate handy; large button design, even under circumstances such as wearing gloves, is also very easy to operate. Shutter button is used with the EOS-1D series of the same type of components, semi-pressing the shutter button is fully in accordance with the distinct feeling, and
EOS 5D Mark II the same. In terms of performance, in addition to changing the location of the power switch in order to enhance operational, the can be given “three-dimensional electronic level viewfinder” and other multi-functional multi-function button to configure the main dial on the side, which can be set at any time you want to use the function . In addition, the newly added single button press RAW + JPEG, you can now quickly select picture quality according to various scenarios
Flash and accessories introduced
EOS 7D’s built-in flash can be the corresponding angle 15mm lens (equivalent to 35mm to 24mm lens angle specification). As the irradiation angle designed to be wider and wider range of light exposure, so to improve the indoor shooting and so on to cope. Indicated that the amount of light flash flash index 12 (ISO 100 • m). ISO 400 under the aperture value is F4, then flash the illuminated area in front of the camera can reach to about 6 meters.
