Please apologize the mundane subjects and the mess of my studio
I wanted to test the C-Rex Planar 2/50 on the 5D Mark II
Of course hand-held in front of camera and of course, there can be no infinity due to register distance.
I think these should be the first C-Rex PLanar 2/50 on full frame DSLR ever posted on the web - unless I missed some.
Pardon my excitement but this is the very first time that I see a Planar lens that is completely immune from CA wide open.
I promise tomorrow I will take some better samples with not so vomiting subjects Laughing
For now, just for the sake of science - all wide open:







I could kill for this detail and bokeh together in one image.

no. i`m not joking
accidentally i added emoticon.
i`m asking because c/y planar has some loCA at f/1.4-2.8(like all 1.4 lenses i had)
bokeh seems to be beautiful

great planar signature!
I know another perfect planar, the makro-planar 60

Sorry, what is loCA?

longitudinal chromatic aberration

This is a 100% crop of the specular highlights in the last image.
I never saw anything like that in any Planar that I have used so far - and I have used quite a lot!
Do not confuse chromatic blotches with CA - the shots were taken at 3200 ISO so they show some coarse chroma noise.
I don't see any CA of any kind in here - and this is the "bitchiest" camera for CA, because it emphazises all of it, due to the zero-gap closely packed sensor cells.
If this is what shows in the 5DMkII, consider that a normal 5D will be double better, and film camera, well, not even to be considered given the background grain noise:

P.S. Lightroom control for CA are set to 0 and control for defringe is set to off !

Cristal clear. No CA at all on my screen.
I like that keyboard.

So, how are we going to mount these lenses to Canon body? Smile

@ Sorin: those keyboards are available in several colours and cost nearly nothing. They are made by Kraun you can search for them

With an adapter. I don't know if they exist. I talked to a guy in Italy some time ago and he said he could make one. It would be a tricky adapter as it would have to allow government of the spring that commands the aperture of the lens which is accessible from the bottom of the lens. I don't know if there would be much point in having that adapter done since you would be able to focus only to 1 meter or so.
You could instead focus the lens to infinity if you would use a Leica M8/M9 or a Micro 4/3 camera.
But again it would be tricky, with the Leica the problem would be to guess the right focus as the lens would not be rangefinder coupled. With the Micro 4/3, the lens would become equivalent to a 100mm lens using only the very central portion of the glass, so again I don't know if that would be worth it, because by losing the outer part of the lens result you would miss a lot of the character of the lens (not to mention the DOF change as illustrated by poilu in his brilliant thread).
So all in all I think that until a full frrame EVIL camera will be made, the Contarex lenses are still best used on a Contarex film camera.

Doesn't look too shabby; I don't see much glow, but also not the kind of biting central sharpness that many modern Zeiss/Contax lenses can have even wide-open. Maybe it's the T* coating that is an important missing element.

Well, here's a 100% non sharpened crop of a tiny portion of the second image:



If you consider that it's 3200 ISO hand-held at 1/40 shutter time (thus certainly motion blurred), I would say that resolvance is not a problem here Wink
