End of last week I told you that Sony is developing a camera which has a sort of a hybrid mount. I don’t know how it works but our smart readers found a camera that has a kind of hybrid mount (thanks!). The original Contax rangefinder made from the 1930ies to the 50ies had two bayonets! (Click here to see them on eBay). Camerapedia explains how this works: “This mount is in fact the combination of two bayonets. There is a focusing helical built in the body and the standard lenses mount directly in that focusing ramp via an internal bayonet. So the standard lenses have no focusing ring of their own. The other lenses mount on an external bayonet and have their own focusing ring, only the rangefinder coupling is done via the body’s focusing ramp.”
You can see a nice image that shows the two different type of mounts here: http://www.fotocommunity.de/pc/pc/display/16753502. Now imagine a Full Frame camera with an inner mount for NEX lenses and an outer mount for Alpha lenses. Could it work? Does it make sense at all? I hope my sources can soon give me the answer how this should work for real!
P:S.: Zeiss Ikon Contax I, II and III can still be found here on eBay.
