Greetings,
I decided to publish this few shots because I was always curious if those two version really differs on or new design is only a new marketing approach. And I also decided because I used to shot with older version, I've already taken newer version and I have still possibility to gather those two lenses in one place and time.
You may find those information with a documentation of Contax/Yashica version and current ZF.2/ZE version. New version is larger (filter diameter grew up from 67mm to 72mm), longer (about 20mm), heavier (from 600g to 900g). You may find MTF's attached to documentation, when You compare it, You may find out that curve of newer version is slightly better (peltarion.eu/img/distoldnew.jpg]here at f/1.4). How is it going to result on RAWs? (those are jpg, which were made from RAWs with down-sampling from 70% at fan photos till 49% at cityscape).
Those shots are focused at lower-left letters of front plates at f/1.4. http://www.zeissimages.com/gallery/1155/U1155I1369685765.SEQ.0.jpg

Those photos are taken with Sony NEX-5 (14MP) with manual mode and automatic white balance.
I decided to take very not sophisticated frames. It may help to focus on differences not to interpret their share in final outcome of whole photo.
Those are series photos focused with center plate of fan (label "sOlac"). It was taken with Sony NEX-7, aperture priority mode with auto white balance and ISO100.

(I dropped to shot with C/Y version at f/8)
Second series were taken with Sony Nex-7 and tripod too. The distance was near infinity (between 3m and infinity in barrel scale), ISO 100, I shot in aperture priority mode with multiple metering and auto white balance. I've focused in center group of tree. It is view from my window.

Have You wonder what version to buy or is it worth to upgrade from 1974 version to 2010 version? I answered myself, for me new version is worth to upgrade from older one.
At the ending, I wish to show You those photos, where both are focused at painting but rendering and details of loudspeaker's cable differs significantly for me. Both are taken with f/1.4 in manual mode and automatic white balance. Which lens' performance do You like more?

Thanks for Your time,
best regards, WZ.
PS. I believe that older version is less prone to color-shift at f/1.4, it has better better portability and it has nicer bokeh (IMHO). Newer version is more sharper at wide open (especially at borders of APS-C field) and quality of photos improves quicker while passing the same f-stops with newer version of Distagon 1.4/35. Please feel free for criticism and sharing You own experience with those epic glasses.
