Review: Canon PowerShot G1 X Mark III

If someone wants a daily camera with
1. APS-C sensor
2. Weather sealing
3. Articulating display
4. Zoom lens with IS
5. USB charging
6. Not willing to carry multiple lenses
7. As small and light as possible

G1X III seems like the best option available.

I'm not sure why some people keep asking why would anyone get G1X III over M5/M6.
It's all about personal preference. I'd rather pay extra $ for less weight, less size, weather sealing, usb charging, fully articulating screen.
If you want to save money and don't mind extra weight/space, and always carry a camera bag for the 2nd lens, sure, M5/M6 is a better choice.

M5+15-45mm : bigger, heavier, no weather sealing, not fully articulating screen, no usb charging
M5+22mm : bigger, heavier, no zoom, no IS, no weather sealing, not fully articulating screen, no usb charging
M5+15-45mm+22mm : much heaver, bigger, have to carry extra lens, no weather sealing, not fully articulating screen, no usb charging

More options are always good for consumers. You just need to pick a camera that suits your needs and wants.

Patent: The Next Prosumer DSLR to Get Illuminated Buttons?

jolyonralph said:
This is a great move. Illuminated buttons would be a huge help. Not everyone uses their camera so much that their muscle memory instinctively knows where every button is - especially the ones that are used less frequently. In the dark I'm always stumbling around trying to find buttons.

And then there are those of us who have multiple cameras, none of which have the buttons in the same place.....

Well, you get more shelf-space when you have more cameras. But it can also backfire; when Apple was in dire straights with their Macs, many different models nobody could keep straight anymore - and competing against clones. When Steve Jobs came back, he killed all that.

Well Apple has still variation. There are 16 versions of iPhone for example - not counting color variations.

SL2 / 200D: Question about battery drain / leak currents

I've been pleased with Battery life on my SL2. I keep GPS Turned off, and there is a Wi-Fi file transfer button on top that I use when I want to transfer files to tablet or phone. I just returned from a week in California visiting relatives and spending a day touring San Francisco. I used Wi-Fi to transfer lots of raw photos to my iPhone where I did minor editing with Adobe LRCC, and uploaded them to the cloud as a backup. I haven't bothered to recharge the battery, its still half a charge.

I use live view almost 100% of the time which makes the battery life even more amazing.

SD card refresher for 5D3

Zeidora said:
You can use your camera as a card reader. Just plug in the the USB cable in camera and computer, and that's it. Works like a charm for me on a 5DsR.

If your camera is just USB2, previewing, selecting, downloading a lot of images will be far slower. Many internal readers are faster, and USB3 ones can be quite compact today, even for CF cards.

The Canon EOS Kiss M / EOS M50 Shows Up for Certification

TAF said:
I was visiting a local camera shop, and got to look at the C200. Bingo. They already have a body that is close enough to make modifying it fairly easy.

Just, look at how those cameras are usually rigged for shooting - not so often they are used almost "naked" with just a simple handle. Those bodies are designed for rigging - for shoulder or tripod use.

Anyway, even Hasselblad with its X1D retained the squared design when seen from the front, but made it a lot thinner.

Delay a pulse to fire a speedlite

niels123 said:
Nevertheless, the option to have off-camera HSS with my Speedlites (compared to 1/160 limit with my current Cactus V5 triggers) is a big improvement I think. It gives me the option to use flash for portraits in brighter conditions outside without half your image completely overexposed. What do you think?

HSS is really useful outdoor (or indoor with a lot of ambient light) when you need shutter speed faster than X-sync. As an alternative indoor to obtain faster exposures to freeze motions, faster than some monolights allow (i.e. my Elinchrom RX4 has a flash duration of 1/800 at full power) it may not work for all subjects, you may need very short flash duration anyway.

If the speedlites work for you the better, whenever you feel the need of HSS with more powerful units better to rely on one designed for it, or you may end in an expensive "hit-and-miss" situation, especially if you do it for a living.

I don't do it for a living, model shooting with off-camera flash is just hobby. I do shoot paid assignment though, but I rely on ambient light and fast primes 99+% of the time then. If I would get paid a decent amount for shoots with off-camera flash, I would for sure invest in a high-end monolight.

Sigma 14mm f/1.8 ART Review | Dustin

Random Orbits said:
I appreciate how Sigma upped the ante in the IQ race, but I'm wondering if always shooting for the largest aperture is a good thing. The 35A and 50A were bigger than their competitors (with the same aperture) when they came out but those focal lengths tend to result in the smaller lenses compared to the focal lengths that Sigma is targeting now. The 85A is larger and heavier than the new 85L IS, the 12-24A is large and heavy (albeit 0.5 oz lighter than the Canon 11-24, but the Canon has a wider field of view and is still large and heavy), the 24-105A is larger and heavier than the 24-105L II, and those examples are where Sigma has matched Canon's max aperture. Sigma has pushed into larger apertures with the 20A and others, and now with the 14A and the weight increase is even larger. At some point, photographers won't want to bring a bagful of lenses because they are so heavy. By making them so heavy and by charging higher prices, I'm wondering if they are shrinking their target market because these lenses become niche products. Would it have made more sense to have a 14mm f/2 and shave off half a pound or more? How many people would be willing to tote a 14A in addition to a 16-35/12-24, 24-70 and 70-x00 zoom? Or if you prime, a 14A, 20A, 35A, 50A, 85A, etc.? The one thing I liked about the 14L II when I had it was its compact size. I could easily find space for a smaller lens, but these larger lens make planning for trips harder because most packs are optimized for such large diameter lenses.

I'm with you. I reviewed the Voigtlander 20mm f/3.5 at the same time as the Sigma 20mm f/1.4 ART. The Sigma is WAY sharper, but I ended up buying a copy of the little Voigtlander after my review. Why? It's super compact, and I can bring along a wide angle of view lens without much bag space.

It's a similar argument for why I purchased the Tamron 45 and 85 VC lenses over the ART counterparts (focus issues were another). They are nearly as sharp as the ART lenses, but trade a little smaller maximum aperture for a much smaller/more compact build. They are just more practical to me.

I own three Sigma lenses - but they are all small, mirrorless lenses. (19mm f/2.8, 30mm f/1.4, and 60mm f/2.8). Size matters :)

You beg an interesting question. How many would Sigma sell of a 1 or 1.5 fstop smaller lens - just as sharp, just with 1/2 the glass, etc.

Considering the lackluster sales of the Tamron primes, I would say that Sigma has figured out the marketing aspect just fine. I also believe (from the anecdotal evidence that I receive) that the return rate and resell rate of the Sigma primes is unusually high. I'm a little more informed than the average photographer, however, so I'm less impressed by the easily marketable features and more interested in the complete package for my own kit.

Criteria when buying lens

For me, Budget is always first, otherwise, I'd have one custom designed and made just to my requirements, even if it cost $100 million.

Its hard to conceive most of us not having a budget in first place.

Then, there is the question of what I need,

focal length
aperture
Image quality
zoom or prime
AF or MF
IS or not

Quality is a tricky one, it may be higher or lower depending on the usage I intend, and there are different quality attributes that are more or less important depending on the intended usage, so there is no simple canned preference.

DXO Test on 16-35mm from sony

ITT a load of people who don't understand how DxO works, what DxO intends, or have even bothered to attempt to read DxO's explanations of their measurements.

DxO's measurements for the 16-35 mk III line up with my experience using seven different copies of that lens, on three different bodies. Seven across three is a pretty decent sample size in my book—far more than the average consumer will get through—and when that experience matches up with DxO's numbers (which, contrary to what some eejits in this thread have insinuated, DxO do explain), I see little reason to doubt them or give it a second thought.

As for why the 16-35 and 24-70 test so differently, you'll find that is the nature of all wider angles when pitched against longer focal lengths. Longer lenses inherently have finer resolving power as details are larger and not all smashed into a smaller pixel count. Hence all the lenses rated toward the top end of sharpness are >50mm and very few wide-angle lenses manage to resolve detail matching more than about two thirds of any given sensor's pixel count. (With a few scattered exceptions.)

When you zoom in, details get bigger and more easily-defined. Who ever would have thought?

Canon 100mm f/2.8 L IS Macro vs Canon TS-E f/4.0 L Macro

Hector1970 said:
People seem to be saying that a 135mm TS-E would have limited uses.
What would those limited uses typically be.
Would it be an unusual portrait lens.

There’s a lot of talk that it will make for a great product photography lens. Considering the .5x this is what I think most pros will buy it for.

I don’t think it would make a bad portrait lens, and you can be selective with the focus plane to get a little shallower DoF which I think will look unique. I doubt it’s going to replace the 135 f/2 or equivalent because of the lack of autofocus.

Off Brand: Leica Announces the CL Mirrorless Camera & Elmarit-TL 18mm f/2.8 ASPH

HTML:
<em>The new mirrorless camera and lens unite innovation, ease of use and compact design for exceptional visual storytelling</em></p>
<p><strong>November 21, 2017-</strong> Leica Camera unveils the latest addition to its APS-C system with the Leica CL, a new camera that boasts an exceptional balance of state-of-the-art technology, mechanical precision and intuitive, classic design to make it the ideal everyday companion, a perfect fit for all types of photography. With stunning image quality – even in low-light scenarios – new electronic viewfinder technology and superb video capabilities, the Leica CL is the ultimate tool to capture everyday moments, all customizable to the photographer’s style. Available on its own or in two new camera-and-lens kit options, the Leica CL makes it simple to incorporate the art of photography into one’s daily life.</p>
<p>Alongside the Leica CL, the iconic photography brand is further diversifying the APS-C system’s portfolio of lenses by introducing the Elmarit-TL 18 mm f/2.8 ASPH., the smallest-in-class wide-angle lens with supreme imaging performance.</p>
<p><strong>Evolution of the Leica APS-C system portfolio </strong>

With the launch of the Leica CL, the Leica APS-C System now encompasses two remarkable camera models, the Leica CL and the Leica TL2. In technical terms, the two cameras are equals, but retain stark differences in regards to their design and handling. The Leica CL reflects the traditions of Leica with its iconic industrial design, classic physical button controls and dials, while the Leica TL2 embodies a futuristic look, featuring a touchscreen and full-body aluminium. Coupled with the extensive portfolio of lenses, the Leica CL and Leica TL2 make for a formidable system portfolio offering an array of specialized and distinct photographic experiences.</p>
<p><!--more--></p>
<p><strong>Introducing the Leica CL </strong>

The Leica CL is rooted in Leica’s legacy, calling upon the brand’s heritage look with modern technical features. The instinctual and convenient design of the camera features a user-friendly handling concept, providing for an exceptionally intuitive tool whose compact size and light weight allow for maximum mobility. All essential controls are located on its top plate with just two dials for setting the aperture, shutter speed, ISO value, exposure compensation and shooting mode, for quick and intuitive handling. Keeping convenience at the forefront, all relevant shooting information is viewable on the small LCD screen atop the camera, instantly providing settings and exposure parameters at a glance.</p>
<p>Another outstanding feature of the Leica CL is its built-in electronic viewfinder. With EyeRes® technology developed by Leica specifically for this camera, the viewfinder enables a top-tier viewing experience. Most notable among a number of advantages of the built-in EVF, is the ability to preview the brightness and color of the final image before the shutter release is fully depressed, allowing photographers to always be in control over the composition and exposure.</p>
<p>Alongside an impeccable view of your subjects, the Leica CL offers best-in-class image quality. In combination with the high-resolution, 24 MP, APS-C format sensor of the Leica CL, a Maestro II series processor and fast autofocus system with 49 AF points guarantee brilliant photographs in all situations, including low-light scenes. In addition to being an impressive still-picture camera, the Leica CL also captures striking video at a resolution of up to 4K at 30 frames per second.</p>

<p>Keeping connectivity as a top priority, the Leica CL is equipped with an integrated Wi-Fi module allowing photographers to quickly and easily share their stunning photos and videos by email or on social networks with the Leica CL App for iOS or Android. The remote function of the app also provides the capability for mobile devices to be used as an off-camera remote viewfinder, allowing control of exposure parameters, including when shooting with the self-timer function or from unusual angles.</p>
<p>Thanks to the L-Bayonet mount shared by the Leica TL- and SL-Systems, SL-Lenses can also be used without an adapter on the CL and the TL2. Appropriate adapters are also available for using Leica M- and R-Lenses on the cameras, offering unparalleled creative flexibility and making the Leica CL one of the most versatile cameras in the Leica portfolio.</p>
<p><strong>New Leica Elmarit-TL 18 mm f/2.8 ASPH. </strong>

To complement the Leica APS-C system, Leica is expanding the impressive TL lens portfolio with a ground-breaking new lens. Compact and lightweight, the new Elmarit-TL 18 mm f/2.8 ASPH. holds the title as the smallest wide-angle APS-C pancake lens currently available in the market. When mounted to the Leica CL, the camera and prime lens are small enough to fit into a coat pocket or small handbag – providing incredible images everywhere you go. Despite being just 20.5mm (less than one inch) in total length, the lens sacrifices nothing, providing the unrivalled imaging performance all Leica lenses are known for. Travel photography is easy with this light and dynamic lens, especially when paired with the Leica CL.</p>
<p>As a whole, the Leica APS-C System portfolio of lenses offer exceptionally high picture quality and infinite opportunities for creative photography. In addition to the Elmarit-TL 18 mm f/2.8 ASPH., the selection of lenses currently includes three zoom lenses (Super-Vario-Elmar-TL 11-23 mm f/3.5-4.5 ASPH., Vario-Elmar-TL 18-56 mm f/3.5-5.6 ASPH. and the APO-Vario-Elmar-TL 55-135 mm f/3.5-4.5 ASPH.) as well as three prime lenses (Summicron-TL 23 mm f/2 ASPH., Summilux-TL 35 mm f/1.4 ASPH. and the APO-Macro-Elmarit-TL 60 mm f/2.8 ASPH.).</p>
<p><strong>All bundled up </strong>

To make the stunning new Leica CL more easily accessible to both new and current Leica fans looking to make their first step into the APS-C system, the Leica CL will be offered in two bundle options alongside an accompanying lens. The “Prime Kit” will include the new Elmarit-TL 18 mm f/2.8 ASPH lens, while the “Vario Kit” option includes the Vario-Elmar-TL 18-56 mm f/3.5-5.6 lens, allowing photographers to get into this new camera and growing system with a lens that best suits their photography style in an easy-to-grab kit.</p>
<p><strong>Availability </strong>

The Leica CL and Leica Elmarit-TL 18 mm f/2.8 ASPH will both be available from Leica stores, boutiques and dealers at the end of November. The Leica CL body, in black anodized finish, will be $2,795.00 while the Prime and Vario Kits will be $3,795.00 and $3,995.00 respectively. The new Leica Elmarit-TL 18 mm f/2.8 ASPH, in black or silver anodized finish, will be $1,295.00.</p>

Patent: EF-S 15-300mm & EF 28-550mm Optical Formulas

We don't need superzoom lenses. Something that is good for everything is good for nothing. We buy DSLRs with interchangeable lenses because the Image Quality of a special purpose lens (10-24, 24-70, 70-200) is far better than an all purpose one (10-200 or whatever).

If you substitute "I" for "we" that's perfectly fine. But as written, your statements are ridiculous and manifestly wrong.

5DS 5DSR memory card question

Thanks for the other follow ups. It appears I'm really not the only person who has faced this and that spending on expensive CF cards won't solve it.

I know everyone says it's a landscape camera but I find the auto focus to be great for action (I believe it is officially the same as the 5DIII but in my entirely subjective opinion it seems a slight bit quicker than my 5DIII) and the resolution means cropping can be used for birding and in those sort of situations fast image review sometimes has its uses but I suppose nothing is perfect in life!

Sony A7R3 manual drops -- here comes the fine print

Tugela said:
There is a physical limit on how quickly mechanical devices such as iris blades can work, so at very high frame rates they will have to be kept stopped down. Most modern Canon DSLRs can image at 60 fps or more, but there is absolutely no way their iris blades can flex at that rate. DSLR focusing works in a different way, and has far fewer focusing elements, so the overhead on the processor is lower. Accurate focusing requires shallow depths of field, and at 20 fps with a full sensor read (which the Canon processors can't handle) when you need to keep the aperture stopped down you are not going to have enough time to calculate the focus point at small apertures. That is the price you pay for very high frame rates. Canon would have the same problem if they shot at those frame rates. At that speed focusing would have to be handled like video focusing, which does not happen every frame but rather happens dynamically over a number of frames and is independent of the frame rate itself. You need the aperture stopped down for that since you are monitoring trends over time and using that to control focusing. Which is fine for video but obviously would less optimal for stills where you would want focus on every frame. That is where the compromise comes in, it is to enable those high frame rates where the data that is used for focus calculation is less optimal. In situations where you have enough data (wider apertures/lower dof) you can focus at those frame rates. The Sony is behaving more like a video camera at those high frame rates, something the Canon can't do unless it also behaves like a video camera (in which case it will experience the exact same problem).

In any case it is academic since I doubt there is any lens that can focus fast enough at that frame rate. No matter what camera you have it is going to be an approximation.

The hardware for 4K is there in the latest Digic, it just isn't implemented due to the processor overheating. The Digic 7 and the DV5 are the same processors for the most part, just like all of the earlier processors came in families. They don't redesign the processor separately for video or stills, the core logic is the same, you just have areas enabled/disabled to optimize performance for a particular application. Likewise the DV6 will be the same as the Digic 8, when it is eventually used. The DV6 implementations appear to have fans as well, so we may still not get hardware 4K in Digic 8, if the thermal envelope is not yet controlled enough.

It seems that there is confusion in your statement about how still and video cameras process images they take.
There are 3 sets of core functionalities in both still and video cameras:
1. A/D performed usually by external circuitry to get the image/video signal in.
2. Core ARM based functions that don't change regularly. These include Connectivity (USB, HDMI, SD/CF Cards), sensor (Wifi, GPS, tilt/level), display (LCD back and top, OVF/EVF), actuators (shutter, focus, lens drives, buttons, etc.)
3. Image/Video processing using CPU and GPU, that includes: audio processing (in and out), image/video processing (compression), and DRAM/buffer management.

Depending on how the sensor array processing is performed (4:2:0, 4:2:2, etc. also number of bits for color 8, 10, etc.) and how much of this is pushed off the CPU/GPU to the sensor chip itself the image/video processing may vary. The image/video processing is done within the CPU/GPU using the stored processing software. The processing itself depends on how much data you want to move, how much processing you need (e.g. noise, color profile, edge smoothing, aberration correction, etc.) and how much compression you want to apply to the data before packaging it and sending to the SD/CF cards.
Therefore, there is no fundamental difference between the way the image and video is processed and everything is done with a combination of software and hardware.
Canon's technology encompasses all three areas. The focus in between frames is a technology that Canon has developed and is included in all newer version of its DIGIC processors.
Heat management is part of the design process. There is no dedicated ventilation mechanism for the CPU. If the whole circuitry produces so much heat, fan is added, e.g. in XF series.
Some other companies concentrate mostly on the third set of functionalities and for some heat management is an after thought.

Is Nikon in despair?

Mikehit said:
An interesting link, Woody.

I did wonder at his comment:
Nikon's putting a lot of pressure on their top DSLRs to produce. The good news is that the D850 is a great camera, and so are the D5 and D500. Nikon knows how to make good products. What they don't seem to know how to do is find true consumer relevance in most of their lower-level products.

I wonder what he means by 'relevant' - if it means appeal to the customer (and thereby sales) then the only way you can say the D5, D500 and D850 are 'relevant' is by knowing sales against Canon/Sony equivalents: no-one doubts they are all very good cameras but are the things that make them stand out the sort of things that matter to the general market?
Nikon has a way of cascading things like sensors and functions down to their base models so in what way would those models not be 'relevant'?

In comparison to Canon, and pretty much everybody else, Nikon doesn't seem to be doing very much in the Liveview/mirrorless/EVF space. They seem to be betting heavily on high quality DSLR's, a rather pricey segment of the market, and one that may lack much growth potential.

Makes me wonder whether Nikon is heading toward selling it's camera business to Sony, which would suddenly put Sony head on against Canon in high end DSLR's.
