Right, same physical mount but slightly different dimensions for the focusing helical. The standard view is that it's close enough for anything wider than standard, though I suppose in a critical-focus application, wide open and close up, it still might matter.

I wonder what other lens brands are made for the contax?
Besides the modern Voigtlaender wides and the Kiev clones, I think they're all oddballs. There's a partial list at http://camerapedia.wikia.com/wiki/Co...efinder_lenses.

I actually have a Som Berthiot 28/3.3 Angulor in Contax mount; it may be a conversion job. I've never shot a lot with it, but it seems to be a decent lens. The Vade Mecum says it's some sort of variation on the Tessar design, IIRC.
