Here's the address. Click 'contact' at the top right, then click 'Inquiry' on the right, then click 'Camera and Cine Lenses' on the right.

http://www.zeiss.de/en

Fill out the form, and ask Zeiss to produce the ZF/ZK/ZS line for EOS _with_focus_confirm_chips.

Be polite and tell them which lenses you think you would buy in that mount. The current options are...

18 f3.5
25 f2.8
28 f2
35 f2
50 f1.4
50 f2 macro
85 f1.4

I'd want auto aperture too. Like the CV 125/2.5 APO-Lanthar.

Focus confirm is secondary (if that).

OK - we all want auto-aperture, but many of us are prepared to live without it. I know you are ;-)

The problem with auto-aperture is that it requires the lens to have electronic motors for stopping down the aperture, which makes it a significantly different design to the others. I think we might have a greater chance of success if we explain that we are prepared to live without auto-aperture. That may well be the reason there is no Zeiss ZE line.

coincidentally, i asked them this morning *when* the Z lenses will be available with a EOS mount, after all Zeiss mentioned before, that they are working on to make them available with more mounts. No response so far

This is really where it's at for me too. Having a confirm chip glued on an EF mount seems a bit Frankenstein for Zeiss to bother with.

Indeed. And since I don't use focus confirm chips at all, and never will, I'm just as well off buying the old Contax Zeiss glass, if I want Zeiss.

Sorry, I can't jump on the bandwagon unless it includes auto aperture. I don't see the point.

Richard, if focus confirm is all you want then why not buy ZFs and stick a focus confirm adapter on them? It would achieve precisely the same thing.

p.1 #8 · Ask Zeiss for ZE EOS focus confirm lenses

I for a change want the focusing and aperture rings to turn in the same way as the old Contax lenses. I really do not have any use for AF confirm, as I compose before focusing. As for the auto-aperture, I would prefer to have it but can live without it, as I discovered some advantages to shooting with manual stop down.

I'd settle for focus confirm plus communication of the actual shooting aperture and focal length back to the camera. We've seen here in many threads how focus confirm adaptors give different metering results than the plain adaptors so passing all the right numbers back may result in perfect metering.

Do the ZF lenses have auto aperture?

Yes (although, it depends on which Nikon you stick them on. AFAIK only the D200/300 and D1/2/3 series support the mechanical auto aperture control).

I just did the same. It will at least be interesting to compare replies from Zeiss. They are really good about getting back to customers.

Wrong. All Nikons starting from WAY back will actuate the aperture. You will have to use the aperture ring to set the aperture on all of them however. The Dx00 and Dx series are the only ones that will read the aperture setting and meter appropriately however.

So the rest don't really support it then, do they?

Pardon my ignorance here, but how do ZF lenses work on Nikon bodies? Is it a case of physically setting the lens to the smallest aperture and then choosing the aperture you want via the camera body?

I assume, in the same way that AIS lenses work on (some) Nikon bodies. You set the aperture on the lens (blades stay open). The camera knows what aperture you've set, due to the coupling, and it meters wide open and compensates accordingly. When you fire, the camera kicks the lever to stop down the blades.

Okay, thanks, Paul. That's what I thought, but was hoping differently.

Auto aperture (and proper metering!) would be much more valuable to me than focus confirm.
