Hello Folks!
I just picked up a Carl Zeiss Jena DDR MC Flektogon 20mm f/2.8 in MD mount.
I was hoping it'd be a M42 mount but just couldn't resist the price of $100 USD. Now I need suggestions as to what I should do with it Very Happy ! I'm a bit excited since this will be an equivalent 32mm on my Canon EOS 550D...
The original owner did not know much about it (other than the fact that they go for a pretty sum on eBay). Optics are in excellent condition. Minimal dust. No fungus or oil on the aperture blades. Only problem is that it is in MD mount Evil or Very Mad and the aperture ring does not click (it opens/closes the blades but moves freely with no resistance).
Should I go for a Fotodiox MD to EOS adapter? I really want to avoid using additional glass to achieve infinity focus. What other options do I have?
Here are some pictures of the lens.


Many thanks,
George

Definitely not original, they were never made in Minolta MD. As it's a later MC one I'm pretty sure it was M42.

Bad news is you can't put it on an EOS and get infinity, so it will need to be converted again.

find someone to change the MD mount back to M42 or even canon mount, or just buy a glass MD-EOS adapter,

That's what I originally thought. I was puzzled when I saw it in MD mount. Perhaps this is the reason why there are issues with the aperture ring. Can any of you provide me with direction as to how I can get this back to m42 screw mount?

The first thing I would try to do is just unscrewing the silver part Wink

I had this same problem once Smile It might be tight to unscrew, if so pliers come in useful. Congrats on getting a VERY cheap Flek!

It's probably an M42 lens with a simple M42-MD adapter screwed on. The aperture, however, seems to be missing the little ball responsible for the clicks. You'll have to take off the back (after unscrewing the MD adapter, you'll see the screws), take the aperture ring off, and insert that little ball if you have a spare (you can get one from the tip of a ball pen Smile ).

Or you might leave it out. Some people who use legacy lenses to shoot video get their lenses "de-clicked" which means you can do a smooth change of exposure while shooting video. It doesn't affect functionality, it just means you can't precisely change your aperture by 1 stop just by feeling the clicks.

I tried unscrewing it counterclockwise and it was VERY tight. I hope it wasn't glued in place by the previous owner.

I will try getting my hands on some pliers tonight Laughing !

It may have been de-clicked for cinema use. However, there is some clicking going on at f/11, f/16, and f/22. That being said, I don't think the apertures fully close at f/22 or fully open at f/2.8. Is there some kind of adjustment that needs to take place?
