The americans always told me I sound like oxford english.
they tell me that too ... I wouldn't take them too seriously!

At the moment I'm living in Brazil & I can tell you the locals are getting some good laughs at my pretty funny Portuguese!

Nevertheless, it's great to be having the conversations though isn't it? Even if we do misunderstand one another incorrectly at times!!

It doesn't. I believe the construction of ZE was, as it's OP admitted, purely wishful thinking.

He did? Where?

Happy shooting,

Das wär total irre wen Zeiss neue Optik für Canon rausbringen würde!

Würde ich kaufen...

ZE= Exacta

Maybe Canon FD mount?

Not be stupid...but why in the heck is this even an issue...what are all these Alt lens makers thinking by NOT have a Canon mount as part of inventory?

Well, this is just speculation on my part but one reason that they may not offer a Canon mount is that their licensing agreement with Nikon forbids it. Alternatively, perhaps Canon hasn't allowed them to release an EOS mount (thereby reducing competition for it's own lenses)?

Good points! Most likely agreements that are old too. No doubt you are right...the lawyers are involved.

Zeiss does not have, and does not need, a licensing agreement with Nikon. The Nikon F mount (as implemented in the ZF lenses) is entirely in the public domain, and hasn't been covered by any patent for many, many years.

As I said, speculation. Does anyone know if Canon's EOS mount is in the public domain too? If not, it might explain why a Canon mount option is not common among Alt. lens makers.

Well there has to be a reason, it is not a mechanical challenge to make an EOS mount. The adapter mfgrs do it all the time.

But it does not really matter, just curious in a very mild way.

The physical mount is likely no longer protected since it first came out in 1987, but the electronic communication protocols are probably trade secrets and are not apparently available to anyone. (Canon has publicly stated this)

Where do you get the idea that a Canon mount option isn't common? All the third party lens manufacturers have or have had Canon mount lenses. This includes Sigma, Tamron, Tokina, and Cosina. The exception is Zeiss. The electronic protocols are apparently reverse engineered...with varying levels of success.

The clue is in the title that the OP gave the thread, coupled with the "what else can it be?" question.

When I could positively and unequivocally decipher the phrase "I am that I am" I'm sure I'll be able to understand this…

Right, and I don't claim any insider knowledge because I don't have any.

However, I am quite sure this will turn out to be the EOS mount.

AFAIK about 40% of all DSLRs sold worldwide have the EOS mount, so it simply makes sense for Zeiss to address that huge market.

nobody is considering ZA lenses in EF mount

Yeah, I agree & actually I'd be interested in the possibility of using Zeiss lenses w/- an EOS mount.

Apparently they were misconstrued, but my earlier posts were simply trying to make clear that this is just speculation (or "wishful thinking"!) at this point. The Zeiss webpage link is just an inconclusive marketing tease. Though, as you & others have said, it makes sense that it *might* be an EOS mount ...

new full-frame Sony about to announce. I think ZA is most likely.

Zeiss glass for sony already exists. It's the Minolta mount.

only one current ZA lens overlaps the ZF/ZS/ZK lenses. This would add seven more to the four already available. The sony lens stable is very thin right now, having Zeiss sell their lenses as ZA would help sell A900s, which is why I think they're making this announcement now.

the A900 will be the only full-frame SLR with built-in image stabilization, not to mention the top (for now) megapixel count. I can see a market there for both Sony and Zeiss.

A Zeiss ZE lens (i.e. Zeiss to EOS mount) without the electrical coupling to do auto-aperture would not be interesting to me personally. Why not just buy Zeiss ZF lenses and a Nikon D700 or D300 or Kodak F body and get full auto-aperture? You can already adapt Zeiss ZF lenses to EOS as long as you don't mind giving-up auto-aperture. I do mind. I'd rather use my Contax Zeiss C/Y lenses on EOS if I choose to give up auto-aperture since several of the Contax Zeiss C/Y lenses are as good or better than Zeiss ZF lenses at a lower price. So I hope Zeiss either goes all the way and does EOS with auto-aperture (ROM electrical contacts) or they don't even bother.

What bothers me I guess... is a bunch of micro companies in Taiwan can make and sell ROM electrical contacts for EOS auto-aperture for a few bucks and yet the mighty Zeiss can't pick up a few of these and mount them on their lenses Come on....
