Before and After Lightroom with CY 35mm f1.4 on A7 @ F2.0 I think.

Really love how the subject is not flat with contax zeiss lenses. It is not only the depth of feild, but also the massive micro-contrast in them.

Hi. I have a question on sony camera used for contax CY lenses.

Have anyone here experienced difference in using a Sony A7 original to either A7r A7ii or A7rii? I have read some where that A7r and rii have more dynamic range/ also some other post write that it has more micro contrast, thus more 3D.

Thank you

In my opinion difference comes mostly from that A7r mkI and A7r mkII don't have AA-filter, and A7 mkI & A7mkII do have AA-filter. I have two of my A7 (mkI) converted by Kolari Vision to thin sensor filter glass and it has similar rendering to A7r from microcontrast point of view. So in my opinion it has nothing to do with different models, just do we ruin image by blurring it with AA-filter or not.

Back in Canon days there was quite big difference between 1Ds mkIII (better and more expensive AA) and 5DmkII (cheap and blurry AA-filter), and for me this caused quite big differences how microcontrast was perceived by viewer.

Good information and thanks Samuli. I wonder what some of the CY lenses look like on the sigma Sensors.

Sigma sensors require very small ray angle, due to how deep the different color sensors are located.

Majority of C/Y lenses do not perform well with Sony A7 thick sensor cover glass, and peform much better when used with modified thin sensor cover glass. So I would assume majority of C/Y have issues with Sigma sensors.

Thank you Samuli for the info. I will try to find an A7r to compare to A7 and give you some feedback.

Thank your again Samuli,

After find an A7r to borrow and did various test comparing A7 and A7r this is what I found out:
1. Contax lenses including 21/2.8, 28/2.8 35/1.4 50/1.7 85/2.8 85/1.4 35-70 and 70-200 do produce a little sharper detail in image on A7r when zoomed in at 100% and sharper when view to fit desktop screen.
2. The image is clearer on A7r and now seems like A7 produce a little haze in images.
3. Color on A7r is cooler then on A7.
4. When using the 21 28 wide open to f4, the images on A7 give more yellow then normal. This does not happen on A7r.
5. Will be selling my A7 and buying an A7r.

Keep in mind that A7r does not EFCS (Electronic First Curtain Shutter). Due to this you will experience "shutter shock" in images shoot with very common shutter speeds from 1/200s to 1/2s. You can simulate A7r shutter with A7 by disabling the EFCS from menu. Problem when zooming to 100% will be of course magnified with A7r as pixels are smaller.

I have 2xA7 (modified thin filter cover glass), A7r (standard filter cover glass) and A7mkII (standard filter cover glass). Any time I go photographing I need to plan used lenses so that with A7r I will not use longer lens than 50mm. I'm shooting almost 100% from tripod, and 50mm is longest I'm conformatable shooting with A7r. With 85mm I can get sharp images if I apply lots of weight to camera (when it's on top of tripod) and shoot landscape images, but portrait shots are hard to make 100% sure so that I avoid motion blur caused by "shutter shock" - this is with large high quality ballhead and Gitzo 3-series tripod, with small ball head and Gitzo traveler already 50mm will have visible "shutter shock" in most of images.

A7r mkII (or A7r mkIII) is better camera in every possible way, unfortunately comes with matching pricetag. When one does not need IBIS or improved AF, the price is just too much for EFCS and backlit CMOS (36mpix vs 42mpix is so small difference that I don't count it as difference).

The shutter shock issue with the A7r is worse in the portrait rather than the landscape orientation. But there are ways to minimize the affects.

Below are images taken with my tripod mounted lenses and A7r (no they are not taken with the Zeiss 35mm f1.4 lens):

Hi Samuli,

You are absolutely right, I would love to skip to A7r mark 2 but the price is more than double from A7r Mark 1 to A7r Mark 2. I feel that the only reason to use the Mark 2 is to couple it with a high mega pixle lens and with ability to focus fast in FE mount. I could only think of the G Master series lenses or may be the new G 24-105 lens.

Hello, reviving the thread as I recently got a copy of a C/Y Distagon 35 F1.4, which I got at heavy discount as the front element was quite significantly scratched (back element is pristine at least).

No apparent issues in my shots due to the front elements dents, but the lens (as I was afraid tooking the chance) looks clearly decentered, with all the lower left part of the image much softer than the rest at least until I stop down to F5.6.

Does anyone know if there is still a lab somewhere (preferably in Europe) that could still try to fix the lens? Zeiss should not serve it officially anymore, as far as I know.

Thr corners on mine us funky wide open at infinity - does this lens have a field of curvature or is mine just off?

The Sony sensor stack does introduce significant field curvature, yes.
