usm Posted March 7, 2011 Share #1 Posted March 7, 2011 Advertisement (gone after registration) Hi! does a Biogon 25mm without modified bajonet (brings up the 28/90 Framelines) working as a coded 24mm Elmarit? Or does it need the correct framelines? Thanks. Mario Link to post Share on other sites More sharing options...

cbretteville Posted March 7, 2011 Share #2 Posted March 7, 2011 Mario, I seem to recall that Zeiss originally made them with 28/90 bayonet, but changed it to 35/135 after the launch of the M8 so the answer to your question is that it can be either. You can buy a replacement bayonet from Zeiss. If you want to code the lens as a leica 24, you'll need the correct bayonet for the code to be recognized.

jaapv Posted March 15, 2011 Share #3 Posted March 15, 2011 Adding to the above, Zeiss, in the states would not sell me a new m-mount for any ZM lens. That is amazing and I would deal with Germany is I were you. There is no problem with the mother company sending you the parts. Or you could send Zeiss USA copies of the relevant parts from this thread: http://www.l-camera-forum.com/leica-forum/leica-m8-forum/20663-zeica-21-2-8-a.html Link to post Share on other sites More sharing options...

Dougg Posted March 17, 2011 Share #5 Posted March 17, 2011 If your 25 Biogon has the 28/90 flange, it can be machined down to become a 24/35 flange. I had this done by DAG on my lens when I sent it to him for coding. This way you don't need to worry about flange screw positions. Except that one of the screws is positioned at an end coding dot; fortunately that dot should be white, and the bright screw head substitutes well, so my coding works well: 011001 as a 24mm Elmarit ASPH Link to post Share on other sites More sharing options...
Dougg Posted March 17, 2011 Share #6 Posted March 17, 2011 Adding to the above, I think if you want the new screw positions you need to get a new Zeiss lens. I doubt a new type flange would be applicable to an old-type lens. The issue then is to deal with the screw positions as they are on the older lens you have. Not a problem... I mentioned what happens when the screw head overlaps the location of an end white dot. I also have some ZM lenses where a dollop of black nail polish darkens the appropriate part of the screw head and is successfully read by the camera as a black coding dot.
