Sonnar 40/2.3 comes from Rollei XF35 compact camera. I converted it to Sony E:


It's tiny, enjoyable and sharp in the center.
Sony A7R, no post-processing besides resizing. Wide open (no aperture control on lens):

Typical Sony wear pattern. You don't have to take a lot of photos, if you just keep it inside a bag all the time, it will get polished around the corners. Wink

I really don't mind the cosmetics, but mount is more and more wobbling. And it has ~200k shoots. I'm approaching A7RII, but I'm waiting for A7RIII, maybe prices drop Smile

Is the conversion difficult? Your work seems really clean. Nice images produced by this lens too.

After removing lens I used ordinary macro extension ring which was processed on lathe in order to keep proper thickness and size matching the lens. Then I glued the ring to lens and used cheap, slim M42 -> Sony E adapter. It's all about keeping proper distance from sensor and having parts fitting each other.

You should also wait for a low cost new Zenit e-mount camera. Rumors are wild! Very Happy

I know, it's interesting. But damn, I want that Sony A7RII sensor and I bet they'll use A7 one...

Simple. I forgot that these lenses aren't coupled to a rangefinder so the assembly would have been quite clean to begin with.

Yes, just a few screws.
