Leica M3 Industar problem

[qhoti]

Hello everyone!
I've got my first Leica, an M3 DS ex condition from KEH.
I had an Industar 26 M and an Industar 50 collapsible so I ordered an adapter from Fedka. first of all the I-50 doesn't fit because the focus lever cant go past the lens release button shield of the m3.

I guess I'll be shooing with the I-26 for now but when I focus to infinity the focus is off by maybe two millimeters.

any suggestions?

Thanks

You can easily unscrew the infinity lock or file down the adapter ring.

It's not supposed to focus right since the flange distance on Leica / USSR is different. Then again; the adapter might be wrong thickness or the camera might be in need of adjustment.

Many variables to be considered with lenses from USSR and Chinese adapters 😉

I've decided to recalibrate the rangefinder, I searched and found the repair PDF, so far I have fixed the infinity focus but the 1 meter is off, I'm having a hard time turning the 1 meter screw. I don't want to damage it.

What makes you think that the RF needed to be recalibrated?

Because the lens worked fine when I had my fed 2 calibrated for it. What else could it be?

You really need to read this before you start playing around with the innards of your M3:

Long story short is that Russian lenses are not 100% compatible with (genuine) Leica mounts.

calibrating M for FSU-lens should be last option. sounds like something is going horribly wrong here...

FSU lenses aren't fully compatible with Leica bodies. You cannot get both 1m and infinity to get a match with the RF. How did you do the calibration, and do you have a link to the repair PDF that you refer to?

I agree. Don't alter the M3. Buy yourself a lens that is already compatible with thwe M3, nlikle a collapsible Summicron, or a CV lens, or Canon, etc..

I suppose you all are right, I only turned the infinity adjustment, I haven't touched anything else. I emailed David Yau who leaves here in Toronto. I apreciate everyones advice and concern, it's good to know I can receive help when I need it. Thanks.
