The Carl Zeiss Distagon 15mm F3.5 requires a super thin adapter to get it to infinity. This lens may present a problem to the 5D. I was successfully built the 4th generation adapter that got the Zeiss 15 to infinity. The 4th generation will have 4 different thickness to accomodate all of Zeiss lens to infinity and also to prevent the lens from going too much beyond infinity that it bring the lens too close to the mirror and may cause the interference.
Here are my new specifications for all of the new 4th generation adapters:
1) They fit extremely tight to the lens and from the adapter to the camera mount. This way there is no looseness and no potential light leeks.
2) These are made from brass so that they will give you very low friction as you mount your lens.
3) There will be 4 different thickness. This is important because some of these lens may need to be recalibrated. I suggested that you get a few types of thickness and try them on your lens that you are going to keep to see which thickness will give you infinity focus and no mirror interference. Some lens like the macro lens you need the adaper a little thick so that you do not loose the 1:1 ratio.
It took awhile to build the 4th generation adapter to make sure that it will meet the requirement of all of Carl Zeiss lens. This is my last effort to make the C/Y adapter to accomodate the Zeiss lens.
I do not have a 5D but I will visit B&H and I will try out the 4th generation adapter that is designated for the Zeiss 15mm F3.5 to see if it will hit the mirror. Thus, this information will have to wait but we will know.

Son's 2nd generation CZ-EOS adapters ARE Fotodiox adapters (the black ones). I don't know about his 3rd generation adapters, and I don't know the specs on those adapters.
ahh, thanks! Mine is black, with a "tab" (not a screw) that clicks into the notch of the lens, that would be the 2nd gen?
I just got a report from Rob. There is a problem with 50/1.7 AE version that you cannot stop down past f/5.6 on a 5D:
Hey there,
I saw your thread and thought I'd give you my input. So far these are my results with CZ lenses and the 5D:
28/2.8 MM: works fine
35/2.8 MM: works fine
50/1.7 AE (white F16 marking): can't stop down past F5.6 (ie., F8, F11, F16 do not work) as mechanical aperture mechanism seems to get stuck on 5D lens mount
85/2.8 AE (white F22 marking): works fine
I know a CZ21 is a waste on a 10D, but that's what I'm trying to do. Anyone have any luck with this combo? If so, what adapter are you using? My initial tests are giving me some very out of focus photos.
A quick one to all the 5D users—how are you processing your RAW images?
I just installed CS2, got the 3.2 Camera RAW update and was amazed to find that the Canon 5D was not supported. How have you all been processing RAW images?
I tried a different adapter and now I get infinity focus on my Contax lenses. The main plate of the adapter is the same thickness as the old one, but the Canon-mount part looks like it has a different offset.
Yes—sold the 1Ds; much of my work is available light and I really did not like the shadow noise or (in mine, anyway) what appeared to be banding in the shadows.
This shadow noise became apparent on a job at a luthier's studio shooting at 400 ISO, using an Asahi Pentax 24 ƒ3.5. He wanted a contrasty, dark shadow 'moody' look, so we used only one light on his desk for the main illuimination.
I have only shot two jobs with the 5D, and with better glass admittedly, but at ISO 1000 on today's job, the files are really really clean, and the shadow noise is very attractive and soft to my eyes. I will post a few shots tomorrow.
These impressions are just based on one IDs, of course; I don't know how others do in this regard.
Given how easy it is to adjust the infinity focus on zeiss lens I'm unsure why it is so difficult to get an adapter that works with the zeiss lens/canon (as long as there is enough clearance in the mirror box).
If the lens is in-tolerance with respect to it's flange-to-film design specs, the only way to do this is by milling down the adapter in thousandth of an inch increments, thereby bringing the lens in closer to the film plane. But the risk in doing that is the lens mounts may not grip into the adapter's bayonets as tightly as it should. Proceed at your own risk depending on what adapter you have.
Underneath the rubber grip there is a screw. If you losen this screw you can adjust the infinity focus. My understanding is that you shouldn't do this on a zoom because teh adjustment is a bit more complicated but on the fix focal length the adjustment is quite simple and harmless - at least that is what i've been told.
As a side and unrelated question has anyone used the 100f2 on a digital camera - if so how does it compare to the 85f1.4 or 85f1.2 ?
