7D mark II still focus issues?

kklerikk said:
I have the focus issue. I have the 40D, 7d mkI, the 5dmkII, 5dmkiii and 7dmkII from one year and alf. After a wedding season I see all the photos of my second using that camera. 50% are misfocused using Canon and sigma. At first I got angry with the second photographer. But then looking at the pictures with 7dmki not missed a shot. Then we realized that it was the fault of the camera. I also used I 7dmkii for an event and 50% of the photos were wrong. If shooting a burst to a few still subject are right and others are wrong. Unfortunately between taking pictures to see and understand the problem is the past year warranty.If I make a simple camera tests the problem is not known. If few click, under normal conditions hardly the problem arises or is attributed to a personal mistake. I also noticed that the pictures appear blurry than moves. I'm selling it.

My copy now works flawlessly. Had an AF issue early on and canon determined a faulty mounted AF sensor. They replaced the mirror box and performed a complete factory recalibration. I would say the AF accuracy and repeatability is now on par with my 1dxii.

One symptom mine had was that it would not hold afma one day to the next....as if the AF sensor was loose. It would fluctuate 3-5 afma clicks which of course is quite a bit of variance with many lenses.

Rather than sell it, maybe have canon check out the AF sensor and do a factory recalibration. Might be worth paying for it if it's out of warranty than take the loss selling it. It is in fact a great camera and should work exactly as you expect it should.

Question about anti flicker feature on 5DS and 5DMKIV

The anti-flicker simply detects the light frequency (50Hz theoretically?) and forces the camera to wait a fraction of a second when the light reaches its brightness peak (on the sine wave). I think if your color light has a green or blue shade when it's dimmed and no shade when it's on peak, the anti-flicker may help, otherwise it will be probably useless.

Canon EOS Rebel T7's are Next on the DSLR Schedule [CR2]

mileage varies by use and user. while it will work for some people, using 2 prime lenses with 24 and 50 mm focal length is not necessarily a better solution than a 18-55 zoom lens.

i do have a few prime lenses but find myself using the 18-55 STM quite often. to me, prime lenses are specialists, one-trick ponies, exactly the right solition for a specific task, when i know in advance what that task/situation is going to be. more often, for all not-preülanned photographic situations - e.g. "walkaround" in my city or other cities, or alpine ventures/mountaineering in summer or winter - i prefer the flexibility of a zoom. often, i cannot freely chose my vantage point. if i want/need to go small and light, i want a compact camera (like SL1 or in my case an even smaller EOS M) with one compact, light, optically decent, not too expensive universal standard zoom lens on it.

18-55 kit zooms had a poor reputation since earlier versions (pre STM) where optically mich weaker. Canon has corrected this in the current EF-S and EF-M 18-55 IS STM zooms. and nikon) 18-55 kit zooms. I find IQ astoundingly good for such small and cheap lenses. of course there are optical limits - first and foremost f/3.5-5.6 - but sharpness is no issue (unless it is a bad copy). calling current EF-S/M 18-55 STM IS zooms "useless" or "no sharp images in less than ideal weather/light" as someone did in an earlier post is totally undeserved and untrue bashing.

so my advice to (first time) Canon "Rebel" or EOS M buyers is: think about "what kind of images do you want to capture? in what types of situations? what scenes, what subjects? planned/unplanned shootings?". depending on answers, i'll recommend either 18-55 STM without hesitation and/or other prime or zoom lens/es.

Tether Tools Case Air Wireless Tethering System

I have a iusbportcamera2 that I bought on a flash sale from B&H for $169. It fits in the camera shoe, has a sd card port, and will charge a iPhone battery if needed.

The software setup is not clearly explained, but I managed it, I can hook to my Wi-Fi network and remotely tether (live view can control stills and video). Same with my smart phone and tablet. Smart phone, tablet will direct connect as well. It runs all day on a battery charge, and has a fair range outdoors, but trying to control using a tablet from inside the house is difficult, I have to sit by a window and range is short. I do not have outdoor Wi-Fi, or that would be much better. Works on Android,, iPhone, mac, and pc.

This seems well suited for video, it does some of the other common features such as focus stacking as well.

https://www.bhphotovideo.com/c/search?Ntt=iusbportcamera2&InitialSearch=yes&N=0&c3api=1641%2Cbing%2C2761706221%2C108011504843

Something to consider as well, it is definitely not so clunky as the CamRanger.

Review - Canon EF 16-35mm f/2.8L III Lens by TDP

By chance I had a short opportunity today to play around with the new 15-35 III.

What I noticed to far:
- build quality is excellent, feels almost the same as my 24-70 II (also looks the same). Therefore I have no problem with the increased weight
- picture quality seems very good, especially in the corners
- vignetting is pretty obvious and strong but not the 4 stops that TDP shows (at least from looking on the photos, no scientific comparison). I can definitely live with it.

Just my 2c

OmniVision Debuts Second-Generation PureCel®Plus and PureCel®Plus-S Technology and Product Families

HTML:
<em>OmniVision’s Newest Pixel Architecture Brings Exceptional Low-Light Performance and Increased Dynamic Range to Advanced Imaging Applications</em></p>
<p>OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today introduced its latest advancement in leading-edge pixel technologies: second- generation PureCel®Plus and PureCel®Plus-S. In keeping with OmniVision’s tradition of delivering industry-leading image sensors, the second- generation PureCel Plus technology offers significant improvements over the previous generation, such as higher full-well capacity (FWC), better sensitivity, increased signal-to-noise ratio (SNR) and enhanced low-light performance. Though the initial development was focused on supporting small-pixel products for mobile applications, this technology will ultimately benefit many other image sensor applications.</p>
<p><!--more-->

OmniVision’s second-generation PureCelPlus technology showcases various performance improvements, including:</p>
<ul>
<li>20 percent increase in FWC, enabling higher dynamic range.</li>
<li>A newly introduced composite metal grid (CMG) structure, which increases pixel quantum efficiency and enhances sensor low-light performance, leading to a 12.5 percent improvement in sensitivity.</li>
<li>Improved deep trench isolation (DTI) structure, which further reduces color crosstalk and improves the SNR10 (low-light performance index) number by 10 lux.</li>
</ul>
<p>These structure improvements also enable small-pixel sensors to have better tolerance to incident light angles. This in turn allows imaging systems to use lower F-number lenses for better brightness, and to realize lower module heights that are essential for slimmer phone designs.</p>
<p>“Maintaining good image quality and sensor performance for small pixels in low-light conditions has always been a challenge in the digital imaging space. OmniVision has delivered increasing engineering advances over the years to address this market need,” said Dr. Song Xue, senior manager of sensor technology at OmniVision. “Our second-generation PureCelPlus technology enables our end users to capture high-quality, high-resolution photos, even in challenging lighting environments.”</p>
<p>OmniVision’s second-generation PureCel Plus-S technology will empower new families of compact 20-megapixel and 16-megapixel sensors. The 20-megapixel OV20880 and OV20880-4C and the 16-megapixel OV16885 and OV16885-4C are designed to deliver high-resolution images to high-end smartphones across a variety of lighting conditions.</p>
<p>The OV20880, OV20880-4C, OV16885 and the OV16885-4C are currently available for sampling and are expected to enter volume production in the first quarter of 2017.</p>

Firmware: Canon Announces New Firmware for Cinema EOS C300 & C300 Mark II

Yep - that audio-"feature" is a thing i never understood...every smartphone would record high fps with audio... so i am happy to see canon still cares about us users out there.

LOVE THAT SHUTTER ANGLE UPDATE - finally we can switch through framerates without worring the shutter is double the fps or not! NICE!

I love this camera for simple reasons:
- small formfactor (dont use big baseplates/rigs/v-mount batteries) - perfect for motorised sliders and gimbals with a great weight
- quality picture with a fast and easy menues (could be even better and faster - but its okay)
- D-AF does a great job 70% of the time
- color grading is a pleasure with clog3

I would love to see:
- false color on the c300-2

- a BP-a60 (or bigger BP-a90) WITH DTAP to power a external monitors (!!!)
(no battery manufacture wants to do that because the amount of c300-2 cameras out there is too few as they say...)

- a hardware and/or firmware upgrade to realise higher fps with and without centre-crop
(i could understand that 4K60p/50p is probably a thing just for the
c700...but atleast more fps at 1080p with and without centre-crop would
be great. ( if for example the many video-signlal-outputs wouldnt work for higher fps or other features were disabled while high fps, i personally wouldnt care - i just need one video-feed out of the camera at the same time - but DAF while High fps would be mind blowing!)

I would pay a hardware upgrade to keep the camera up-to-date
and competetive any time!

Go canon, go!

Why Focus Peaking Would be Useful on a DSLR Camera

I've used a focus screen with a split prism on my 1D MK III. Not very accurate on a DSLR though. Its like that focus confirmation light, it tells you that you are approximately focused.

Live view with magnification takes time, but it is accurate, and when tethered using my large monitor with additional magnification, I can focus to an extreme accuracy just where I want it.

Canon Q3 Operating Profit Nearly Halves on Post-Brexit Yen Strength

rrcphoto said:
Woody said:
Oh, for you nay-sayers who think the world of Canon is crashing down because they announced a 50% reduction in profits for the first 3Q of this year due to a rising yen, you should read what's happening to your beloved Sony et al.

oh no, it's JUST canon ;)

interesting.. they are forcasting 3.8 million cameras (including P&S) down from 6.1 a year prior.

another huge drop, three years in a row. Sony doesn't break out ILC's probably because they are too scared that people will find out the real facts.

Or Nikon.... 1000s of jobs to go there....
http://asia.nikkei.com/Business/Companies/Nikon-to-cut-1-000-jobs-in-Japan

But... its not due to Cameras. Nikons camera sales are up some 50+ percent. Nikon is being smart, their Semiconductor Fabs are losing money due to poor sales so they are getting ahead of the curve by re-assigning workers, and may offer voluntary early retirements or layoffs.

The Japanese companies still do not layoff employees wholesale like US companies do, but they are finding ways to shift and retrain the workforce as well as offer early retirements.

They do rent contract workers, and, since they are not employees of the company, they don't count them when their jobs go away.

Patent: Canon Develops Variable Optical Low Pass Filter

Mt Spokane Photography said:
I wonder if there is a specific application for this? Adjusting object recognition accuracy due to temperature changes seems like a limited application, is this a issue for normal DSLR users?

I wonder if its going to appear soon?


"Conventionally, light measurement of a single-lens reflex camera has measured the strength of the light with the photometry sensor installed around the pentaprism via the light measurement lens in the luminosity of the object image currently imaged on a focusing screen. It is using image sensors, such as CCD, for the above-mentioned photometry sensor separately from imaging sensors, incorporating the object image currently imaged on the focusing screen, and distinguishing the form and the color of the incorporated image in recent years, and object recognition and color detection are performed and there is a photometry device which aimed at improvement in functional. When the spatial frequency of an object image has a response more than the Nyquist rate of an image sensor, a false color occurs and it may become impossible usually, for an image sensor to recognize a right color on a sensor.
[0003]
Since a high spatial frequency response is required also of a light measurement lens in order to perform object recognition when an image sensor is used for a photometry sensor, a false color may occur like an image sensor. When a false color occurs in a photometry sensor, the color of an object cannot be recognized correctly but there is concern which causes erroneous detection. Therefore, image sensors, such as CMOS currently used for the imaging device, are processing arranging an optical low pass filter or applying a digital low pass filter by the image processing after imaging into an image formation optical path, etc., in order to suppress generating of a false color.
[0004]
Although the low pass filter is inhibiting generating of a false color by restricting the spatial frequency response of a lens and stopping the high spatial frequency component of an object image, the resolution of an object image is deteriorated and deterioration of image quality produces it. In order that the usual imaging device may perform focus adjustment to an object and may always take a photograph in the position of a focus peak, the image quality degradation by a low pass filter is a degree which is satisfactory practically. However, the above-mentioned photometry device is difficult to mount a focus adjustment mechanism in view of the miniaturization of an imaging device, and low-cost-izing.
[0005]
However, if the temperature of a photometry device also changes because environmental temperature changes, a focus gap of a lens occurs, and since adjustment of a focus cannot be performed, the resolution of the object imaged to a photometry sensor will be deteriorated. Therefore, when a focus gap of a lens arose, deterioration of the resolution by focus gap of a lens was seasoned also with deterioration of the resolution by the low pass filter effect, and resolution required for object recognition may not have been acquired.
[0006]
The following technology is proposed about the prevention from image quality degradation by a low pass filter in the imaging device which does not have a focus adjustment mechanism. At the Patent document 1, a spatial frequency limit effect is provided with a variable optical low pass filter, and the focusing state of a photographing object is detected, and by weakening the spatial frequency limit effect of a low pass filter according to the amount of gaps of a focusing state, though deterioration of resolution is suppressed, it has composition which inhibits a false color. "

From what I can tell, the purpose of the patent is effectively to improve the resolution and color accuracy if iTR metering in Canon cameras. All the specificity aside, sounds like a good thing to me, and since iTR is being used in more and more Canon DSLRs, it should have fairly broad application in that context, even if it isn't something that the user directly sees day in and day out with their camera. It should just mean better AF with more consistent lock and tracking.

CMOSIS Announces New 48mp CMOS Sensor

Canon Rumors said:
<p>Its pixel offers 64dB optical dynamic range at full resolution and up to 68dB in subsampled 4k mode, and the imagers benefits from the implementation of sophisticated new, on-chip noise-reduction circuitry such as black level clamping to enable it to capture high quality images under low-light conditions.</p>

64 dB is what, about 11 stops?

CMOSIS is doomed!

Thinking about upgrading my 1DX to the MK2

I can't speak to the 1DX I, but I have been very happy upgrading from the 5D to the 1DX II. However, my understanding is that you won't see much of an improvement at higher ISOs, the sensor improvements are primarily in improved dynamic range at the low end. I was never a "shadow pushing/banding" sort of guy, but I do appreciate working with the files over those of the 5D III, they just seem to be a lot easier to work with.

Valvebounce said:
...Has the mkII been out long enough for the price to drop and stabilize from the initial 'early adopter' point? ...

Before I bought the MK II, I took a hard look at the Canon Price Watch numbers and also did a search for specials around Thanksgiving to Christmas, basically I concluded that the 1D X saw almost no price drop until about three years in and could find no bargains around the holidays, so I don't think the "early adopter" issue is as big of a factor with the 1 Series.

Mirror-less is killing the DSLR

Hillsilly said:
Any sales comparison that doesn't include the world's best selling cameras (ie the Fuji Instax line) lacks authority.

This is from last christmas - http://www.imaging-resource.com/news/2015/12/31/amazons-best-selling-camera-item-this-holiday-was...film

I'm sure this year's sales volume will be even better, and I suspect the only reason digital sales are down is because everyone is buying Instax cameras.

Come on man. That's an instant film camera. :)

Leica Announces the TL System

HTML:
<em>The new camera system impresses with perfected features, unique design, precise, high-performance lenses and a range of functional accessories and technical equipment.</em></p>
<p><strong>Wetzlar, 8 November 2016.</strong> Building on the Leica T camera system, which has been continually advanced in terms speed, ease of handling and flexibility since its launch in 2014, the Leica TL embraces all the perfected features and leads the innovative camera concept into a new generation with even more innovations and new aspects of its design. One of these innovations is the doubling of the size of its internal buffer memory to 32 GB. Other new features are improved autofocus, especially in AF-C mode, and optimised compatibility with lenses from other Leica camera systems. For instance, the Leica TL now supports SL-Lenses with OIS and allows the use of Leica R-System lenses in combination with the R-Adapter L. A new Leica TL app with revised functions offers additional options for sharing pictures by email or on social networks and is now available for the first time for Android as well as iOS devices.</p>
<p><!--more--></p>
<p>The Leica TL will in available in three colour options from the date of launch: the silver and black versions are identical in design and construction, while the titanium-coloured option is distinguished by a bevelled edge (chamfer) to the top and bottom plates. Functional camera accessories, such as the new high-quality protectors in Nappa leather, which can stay on the camera when changing the battery, and colour-coordinated carrying straps in stone-grey, black, red and cemento, round off the TL system portfolio.</p>
<p>In combination with its high-performance image processor, the large, APS-C-format, CMOS image sensor of the Leica TL guarantees exceptional imaging quality and delivers brilliant pictures with outstanding contrast, finest detail resolution and natural colour rendition – even in unfavourable lighting conditions.</p>
<p>The comprehensive portfolio of lenses for the Leica TL offers an ideal range of focal lengths for all situations and types of photography. The TL-System currently comprises six lenses – three prime lenses and three zooms – that meet the needs of every photographic situation. The two fast prime lenses, the Leica Summicron-TL 23 mm f/2 ASPH. and the Summilux-TL 35 mm f/1.4 ASPH., are classic focal lengths for reportage photography, and the APOMacro-Elmarit-TL 60 mm f/2.8 ASPH. complements them ideally as a lens for finely detailed close-up photography. The three compact zoom lenses, the Leica Super-VarioElmar-TL 11–23 mm f/3.5–4.5 ASPH., Vario-Elmar-TL 18–56 mm f/3.5–5.6 ASPH. and APO-Vario-Elmar-TL 55–135 mm f/3.5–4.5 ASPH., cover an entire range of focal lengths equivalent to 17 to 200 mm in 35 mm format and deliver outstanding images with rich contrast from corner to corner of the frame.</p>
<p>All Leica TL-Lenses impress with exceptional imaging performance at all distances from their close focusing limits to infinity and deliver pictures with the inimitable ‘Leica look’ and unique bokeh. Developed by optical design specialists in Wetzlar, they offer the exceptional imaging performance for which Leica lenses are famed. The combination of optical and precision engineering expertise and the use of finest materials in their construction ensures their constant quality and reliability in use.</p>
<p>Thanks to the L-Bayonet mount shared by the Leica TL and SL cameras, SL-Lenses can also be used without an adapter on the Leica TL. With this, Leica once again carries forward its fundamental principles of cross-system compatibility and sustainability, which is now also reflected in a uniform product designation. Appropriate adapters are also available for using Leica M and R lenses on the camera.</p>
<p>The particular trademark of the Leica TL is the unusual design of its extremely compact body. Each camera body is precisely machined from a single block of aluminium in the Leica factory. The use of premium materials and their processing in an elaborate manufacturing process are unique in the history of camera construction and lend the Leica TL-Camera an unmistakeable look, feel and solidity.</p>
<p>The handling concept of the Leica TL is clearly structured, intuitive to use and concentrates only on relevant functions. The ‘control centre’ of this concept is its clearly laid out, 3.7- inch touchscreen display. It is generously dimensioned and generates a bright and clear image that allows precise and reliable assessment during subject composition and in playback mode. Numerous functions in capture and playback mode can be controlled simply by touching the screen. The only other controls are four ergonomically positioned haptic control elements that are intuitive in their operation. This ensures that camera users can concentrate fully on composing their pictures – without any unnecessary distractions. The freely configurable MyCamera menu of the Leica TL offers even greater flexibility, even in spontaneous snapshot situations. This means that the photographer always has fast access to the most frequently used features and personalised presets.</p>
<p>Thanks to its integrated WiFi module and the function for setting up its own mobile hotspot, the Leica TL can conveniently transfer stills and videos by WLAN to smartphones, tablets, laptops or desktop PCs from almost anywhere and allows users to share their pictures and films by email, on Facebook or in other social networks. A free Leica TL app for iOS and Android devices is available with the release of the camera. A particularly practical feature of the app is the remote function. This lets users connect a smartphone or tablet to the camera by WLAN as an electronic viewfinder for the Leica TL and offers remote control of shutter speed and aperture settings – for example for shots with the self-timer or from unusual angles.</p>
