Summarit Variants

[stu weinstein]

I have 2 Summarit M 5cm Lenses. Side by side there are some obvious

differences in the cosmetics and the actual shape of the parts-so much

so that they would not interchange. Is there any site which has

detailed info on Leica lens variations and construction? Thanks. Stu

My guess is that one of them was originally in LTM but bonded with an M adapter.

 

Why not post some pics?

Stuart - I have two versions myself - One I bought with the intention of fixing - the other to "guide" me - I know what you mean - I've searched a bit and have not found much relating to the differences - good posting

I tried to photo the two lenses, but my 3mp camera wont focus that close. I used the scanner which sort of distorted the lenses. One lens has a red dot and the other has a plastic button. The infinity lock knobs are slightly different in shape. One lens is a couple of mm taller. One has no bayonet mount for a filter. One is in meters and the other in feet. On one the aperture ring turns from right to left and the other is the opposite. One has the apertures engraved on the ring and the other on the body. One has a thread in front nameplate and the other is held by a set screw. I'm sure there is more. Both are "M" lenses. I don't know about the inside construction.<div></div>

the filter thread is also diffeent, the earlier uses clip on ones, the later use E41 filter, screw in.
