MD lens to Bessa R2A(Leica m) body?

[pdeeh]

If it don't need to be fast ... well, one of my personal favorite 50mm lenses for Leica (Industar-50) cost me 8$ something.

Oh no, did I overpay at $20 for my rigid industar 50 ?
Mind you it was one of Brian's ugly spares and he'd cla and shimmed it

Hahaha [emoji33] sorry for asking but shimmed?

Heck, I didn't know the Industars needed shimming I thought that was only necessary with the fast Jupiters ... Anyway, mine is a rigid too (black) and gives surprisingly good results on my M4-2, even wide open. It does need a hood though as it tends to flare badly. Only thing I don't like is the rather loose aperture ring and the quality of the M39 threads which are ... well ... good enough for my cheap LTM to M adapter but not quite good enough for my IIIf (lens will bind). But one day I will just clean up the good ol' USSR black paint from the threads and then it will probably mount on my IIIf, too.

Because I use the bessa and not a leica I don't need an adapter that brings the viewfinder 50 frame. So I could but some cheap evilBay adapter and then go from there? A brase tube and some cutting.

I am not familiar with the Minolta MD lenses, but the posts by B. Sweeney which are linked to in this thread indicate that this hack was (1) only possible with the Pentax lens because of the way the rear of the optical cell/mount is designed and (2) only possible with this Pentax lens because its effective focal length fits the ramp of the cam follower of the Leica M RF system

You said you have some russian M39 lenses and personally I don't understand why you do not simply invest 10$ in a china M39 to M adapter (or 30$ for a genuine one) and start shooting right away. If you absolutely want Japanese glass on your camera you can later save up for a user grade Canon 50 f1.8 in M39, it is a superb lens that can be had for less than 100$

IMHO, you will have to make up your mind if you want to spend your time with (A) taking pictures with your new camera OR (B) disassembling lenses, tinkering around with adapters and what not besides lots of test shots until you got everything right and possibly ruining your Minolta lens and camera in this process

I have already ordered m39 to Leica M adapters from Amazon, have to wait maybe two weeks

Having a 50 mm 1.4 Minolta would just be very cool. The idea that people have made those SLR lenses fit onto a leica interests me. What people can make when they put their mind in to it, is just stunning

I think you can mess around with lenses (or films or developers or darkroom techniques) as well as take photographs, it's not an either/or unless you want it to be.

As for shimming, the issue is that Soviet LTM lenses were not exactly the same registration as Leica, plus they were known to be a bit variable in accuracy to their own standards. So mounting a Soviet LTM on a Leica (or Voigtlander) body might mean you ended up slightly off to infinity focus, or maybe a bit of a front or back focus problem dependent on aperture.

You can adjust this by adding or removing shims within the lens.

I think when Brian dismantles any lens, he'll check for such things and would correct it as a matter of course. Many of us I'm sure probably wouldn't even notice the difference between most lenses whether shimmed or not, unless the problem was really quite gross, but Brian likes things just right.
I'm sure there's a zillion threads on shimming if you care to google

Thank you for the quike answer. I hope there are no problems with my lenses. But i think my jupiter 8 out of focus. It goes past infinity on the apature anyway. Thank you all for the answers. Cant wait to go out shooting

Okay so today I got home my minolta MD to Leica M adapter to go shoot during this weekend. Im wondering tho if I can use the normal 50 frame on my Bessa R2A? or do I need to screw my "extra" viewfinder piece?
