One area that's always seemed vague to me, as I read about those new lenses: It always seemed confusing whether the Zeiss glass was only for 35mm bodies, or whether they were to go into the MediumFormat bodies as well. Everything I read that mentioned Zeiss always seemed to refer only to 35mm. This link that you mention seems to refer only to 35mm too, unless I"m missing something.
Since this is a MF forum, (right Graham?), it seems worth mentioning this factor. Seems like a lot more effort and energy is being put forth toward 35, rather than MF, with these new lenses. I guess that's where the market is, and the volume.
Maybe I'm wrong about this whole thing, but there seems to be a clear line between 35 and MF with Hartblei.
Having said that, adding the Tripod Adaptor is a great idea. The Canons should copy that. You want the body to move; not the lens. That way, they line up damn near pixel to pixel.
Vague is being polite, when you combine information from a Ukranian lens maker and throw in an "alliance" with a medium format maker.
Bascially without having hard facts historically Harteblie lenses, regardless of mount have generally been designed to cover a 645 format and the 35mm versions, even pre zeiss glass were just 645 lenses with a few different 35mm mounts. (Actually 6x6 Kiev lenses with different mounts).
Now with Ziess glass they might be sharper, though I like the older softer Russian Spy Lens glass, the build quality is always been kind of hit and miss with every example having it's own unique character.
I have two SuperRotators one for the Contax,, one for Canon and the Contax version just got stiff and takes almost two hands to makes adjustments where the Canon version is still smooth and easy to work.
The difference is the Canon version is never really sharp, the Contax version is, (though I never found Canon's early TS's that sharp either).
I doubt seriously if you will see the Zeiss versions of these lenses in anything but 35mm and if they do go to 645 it will probably be only Phamamamaiya and even then probably 2012 before they are out.
Still for the prices, I doubt seriously if you'll see any of these lenses out in the marketplace.
