I have a shell adapter at 1.5mm on my CZ21....as that is the thickness Bob Shell said is required. Perhaps mine was worked...I don't know though as it came with the lense. I do have infinity focus though on my 5D. Great lense. $2700 - $3000 USD seems like a fair price depending on condition.
No, Christian, the adapter you have wasn't shaved down as far as I know. I bought two of them from a local shop, both looking identical and not being marketed as custom made for the 21mm.

I have four Huppert adapters and a dozen of Y/C mount lenses, including the D2.8/21. There is no combination that does not yield proper infinity focus on my 5D. Carl Zeiss lenses did always yield correct infinity focus on Yashica and Contax cameras, so it is difficult to understand why different lenses would require different adapters for the 5D. Perhaps adapters should be matched to the camera instead of to the lens. For Canon lenses can focus past infinity, which reduces the need for narrow tolerances of the flange-to-sensor distance.

Those are words of wisdom. Thanks. It really irks me that people are still blindly spewing the Canon 44mm flange to film distance specification as some sort of sacred cow "never-to-be-doubted-gold-standard" when reality seems to prove otherwise.
Regarding the Bob Shell (and other) adapters, I had inhereted several of these along with various lens purchases. None of them was even at the 1.5mm thickness he advertises them at anyway. I compared my dial caliper against a local machine shops dial caliper, this is a multi-million dollar machine shop that makes precision parts for multi-million dollar manufacturing factories, and my dial caliper tested accurate. Bob's adapters I had were anywhere from 1.55mm to 1.65mm, yet he still claimed they were all 1.5mm. Go figure. Same denial with Fotodiox. Some folks would rather not hear the truth.

see my email and my post above. I am serious, but I thought checking is better done by the seller! :-)
Also, gets my SLRc in someones hands who may be able to say where IT is off (However, every Leica and Zeiss MF lens I have tried on it is spot on! It is just this 21mm 135 zeiss that seems to have infinity focus issues. Maybe only SON's adapters really work on some of them)
best regards

You mau be absolutely right. Itcouldbe that theKodalSLRc is just off the Canon that the adaptors dont work right.
Now, why do allOTHER lenses work perfectly? (also with Leica, focus confirmation with that Rudolf adapter!

Do most people not think that a new zeiss zf / zs 21mm is just around the corner?

My hunch is that the original Contax designs are still under exclusive license to Kyocera. A new 21 that doens't infringe could be a pricey proposition.

p.3 #9Zeiss 21mm for Canon EOS?
So did kyocera only have the licences for some of the lenses..i.e. 15, 18 and 21 as there are new zeiss zf 25, 50, 85 and 100?

John I dont think Kyocera has rights on the lens design, probably for the mount, not for the glass. This is Zeiss' base know how. Have a look at the datasheet of 1.4/50mm Planar, the cy, N and ZF have the same design and theoretical performance IMO

Andi-
Maybe so, but if Yashica had exclusive rights to distribute those lenses, later transferred to Kyocera, Zeiss may not be able to make them exactly the same and still distribute them legally. They said the new ZF's have improvements over the CY lenses, so technically maybe they are in the clear of their current ZF offerings, but perhaps making subtle changes in the 21 design to stay within the law may be to costly because it is a complicated design.

The CZ D21 C/Y (of Kyocera manufacture) has a floating group. The ZF lenses are made by Cosina, a company that lacks this technology. The two ZM lenses with floating groups - D15 and S85 - are necessarily made by CZ at Oberkochen for this reason, and are priced accordingly.

p.3 #13Zeiss 21mm for Canon EOS?
no floating element? Zeiss's datasheet touts this lens' ability to focus only 6 cm from the front of the lens. how do they do it (well) without a floating element?

I dont doubt that this lens is worth the price the photographer is ready to pay for it ;-) I just think that Zeiss will find a way to make decent WA lenses in the futur. The price might be rather high of course

Have you looked at the Leica 19mm? It's a bit more reasonable and produces stunning pictures...

I just sent you an e-mail. I'm willing to work with you to get things the way they should be with this lens.
As I mentioned in my e-mail, I use the 21mm mainly on an Aria, so most of what I have is sitting beside me here on film. Infinity focus is not a problem, as expected without an adapter added to the equation.
I saw your post offering $4000 to get you up and running with the lens, which would be great for my bank account, but my asking price (or close thereto) is all I ask.

Don't know why some list crazy high prices for their CZ 21.
Don't know if this shop is for real or if they actualy have the lens in stock take a look if you want:
