Dante Birchen: So it's popular is it?

The Lens rental review states the Sigma is a bit soft and the reviewer would opt for the Canon version instead.

Speaking only for myself, as an amateur, I would opt for the Sigma since the OSS out weight the slight softness that was reported. Personally, I did not see any softness in the sample images in the review, that is to say it is sharp enough for me. Again only speaking for myself, I know from my past images that a sharp lens that is hand held can result in less "keepers" compared to another lens with OSS under certain conditions. If I missed capturing that golden opportunity, the once in a lifetime image, because of camera movement on my part I would kick myself for not getting the lens with OSS when I had the chance.

On article Sony a9 banding issue: fact or fiction? (734 comments in total)

Thank you for the interesting analysis. Were you able to reproduce the results in a controlled lab environment? If so then the test should become part of your future benchmark tests that are used to evaluate digital cameras performance.

mosc: I would love to see how the sigma stacks up against the manual focus Venus Optics Laowa. I don't think f1.8 vs f2.8 is that big a deal to most (lets call that even considering the Sigma is 14mm and the Laowa is 12mm), even autofocus stops being that valuable at this kind of width, but if the Sigma can match the Laowa's party piece (not making me nauseous at well past 90 degree FOV), I'd be interested.

I agree it should be interesting to see how the two stack up against each other and others from Canon and Nikon. Googled the Laowa lens and found one star image corner view which shows some coma. When compared to the Sigma corner star image example it "appears" that Sigma "maybe" slightly better. If this is true then Sigma may have edged out their completion in this one unique application. http://www.the-digital-picture.com/Reviews/Venus-Optics-Laowa-12mm-f-2.8-Zero-D-Lens.aspx

Nikita66: love the idea of this 14 1.8.

Now, pleeeease do an APS C version:: compact 10mm 2.8 - but with removable hood and filter thread.

Do you mean something like the Rokinon 10mm f/2.8 ED AS NCS CS Lens?

digilux: So, assuming I shoot f5.6-f11 all the time, should I trade in my Sigma 35mm f1.4
for this 24-70?

Asking others what to do for your particular situation will not answer the question. Only you can determine which lens works best for your situation. Consider renting the new lens and make your own comparisons. Then share your findings on the appropriate forum.

Maybe in the near future DP will compare this and the other super wide angle lenses and include astrophotography applications in the mix. The faster lens design should allow the photographer to use lower ISO which should improve the image quality or they can trade that off for reduced exposure time which will reduce the star trails when not using a star tracker. Googled the subject and found two astrophotography test cases (with and without star tracker) and wide open and stopped down by Sigma: https://www.sigma-global.com/en/lenses/cas/product/art/a_14_18/testshot/

Richard Murdey: Maybe there is a Zeiss 35/2.8 lying in pieces over at Samyang R&D?

You maybe right but then again 35mm lens design is not exactly new.

trungtran: Not 35mm, but a Canon 40mm STM with MC-11 would be an alternative as well.

I tried that combination and it did not work that well on my a7s, complete with updates to the MC-11 and camera body. I have been considering the Zeiss 35mm lens for a long time now but could not justify the cost given the application of taking candids. Now I have a choice.

Chances are once you stop this lens down to 5.6 or 8.0 most experts will not be able to tell it apart from the Zeiss equivalent. Even at wide open most people, including myself, will not be able to tell them apart, especially if corrected by Lightroom. Given that is the case the only issue will be how well it plays on the Sony camera and that remains to be seen. Assuming there are no glaring issues I will buy it. In my opinion, it complements the a7s attributes of small size and light weight.

On article How do you know you need a new camera? (410 comments in total)

The nice part about shopping for a new camera is, if you wait long enough something better always comes around. The opposite is true once you buy one.

In 2020 the Japanese will be broadcast the Olympic games in 8K. While this particular monitor may have shortcomings it is just the beginning. As with anything new, the price will drop as the manufacturers ramp up production and they will offer larger sizes. For PCs, the video cards and interfaces will catch up as well and costs will drop. Personally, I will hold back my judgement until I see this monitor in person, since it could offer other attributes making it worthwhile.

On article Sony a9 Full Review: Mirrorless Redefined (2748 comments in total)

Sony is still pushing the envelop which in turn enables photographers to create and capture images that eluded them in the past. They are listening to their a9 target consumers, my guess is, the professional sports and wedding photographers. Sony is providing them with some of the features. Leaving the door open to future model improvements.

For example the 20 fps. While some will claim they don't need that capability, it is good to have it available when you do need it and as mentioned in the report one can always select a slower rate. The same could be said about all the features the a9 camera provides.

Projecting forward the development trend that Sony is on, we are in for a treat with cameras that we can only begin to imagine at this point in time. Sony is creating their own market by creating cameras that others will have to copy if they want to stay in business. At this rate my guess is Sony will soon become number one.

On article Analog gems: 10 excellent, affordable film cameras (815 comments in total)

Nikon F. First modular system camera to introduce the F-mount vs M42 screw mount; interchangeable focusing screens, backs, motor drives and prisms; 100% viewfinder; focal plane shutter uses a titanium foil blinds vs cloth.

The all black Nikon F that I sometimes use has the standard prism without a meter which frees me from viewfinder distractions, while it is slow to change rolls, it engages my experience, knowledge and skills to produce the image.

Neither the lenses or body are weather sealed, nor does it have auto-focus or auto-exposure, it does not take videos, it does not have GPS or transfer images to social media.

Yet I can still imagine and create the images. In the end that is all I ask from a camera. To enable me to create, to enjoy life by sharing memories with others. To that end the Nikon F serves me well.

Nothing new under the sun. Switching systems has always been a relatively expensive proposition for professionals and non pros alike in the past as it is now and the future. Sheet to roll film, view to miniature cameras, film to digital, manual to auto focus, etc. etc. This is to say the technology is always evolving for better or worst. At the individual level we should be thankful that we have a choice, an opportunity, to select another solution that enables us to create images that may have only existed in our imagination up to this point. We are aware that a the current rate of change whatever we own or purchase today will be obsolete tomorrow. At some point we may learn to except the fact that we cannot fully utilize what we already own. That the greatest limitation to our creative expression is not the equipment we use but our lack of imagination and knowledge to use it.

On article Fujifilm GFX 50S Review: Modern MF (908 comments in total)

Just me, a rank amateur, I would go old school with a 4x5 or 8x10 view camera to create quality B&W portraits and landscapes images. Yet I can see why a working professional studio/commercial photographer would lean towards GFX. In regards to lenses, my guess is third party adapters will appear allowing MF meduim format lenses to fill the lens gap, assuming auto focus is not as strong requirement for studio and landscape work. If one is shooting a fashion runway event or some other moving subject the current AF lenses may not suffice either. Speaking only for myself, the analog or digital meduim format camera systems are best suited for high end portraiture and landscape subjects that rarely move. For myself, I only use meduim or large format cameras when image quality is paramount thus requiring the camera system is on a rigid tripod with a remote shutter release.

Speaking only for myself, I would not be to surprised if Apple eventually got out of the computer market altogether over the next ten years. They seem to have a greater profit on their iPhone and iTunes products and services. Albeit iTunes is no longer fairing well either and be phased out as well or be reinvented. My guess is Apple will continue to develop and release other hardware products if only to sustain their heritage and loyal fan base but at a slower rate over time as sales drops off certain product lines This shift can be seen in the Apple stores over the last ten years. If this is the case, eventually the Apple stores will start laying off employees as the company turns the corner and heads downhill as the Steve Jobs inertia continues to wear off and the company loses its innovation edge. The only thing that might save their soul is the Woz, but that would be a long shot.

What I am looking for is a 3 axis Gimbal system that can supply power to the Sony mirrorless camera via the USB charging port on the camera. Are there any?
Thank you in advance.

On article The whole nine yards: Canon 35mm F1.4L II USM review (338 comments in total)

IMHO this review is well written. One side effect may result in a decreased the resale value of the previous Canon 35mm F1.4L lens. The side by side comparison of the two Canon lenses provides more than enough motivation to upgrade from the version one lens to either the Sigma Art lens or Canon version 2 lens. Given the higher cost of the version 2 the Sigma Art lens appears to be better value and choice for myself.
