Inner reflections inside M6 - who knows the cure???

Can you give a bit more information
- More pictures with the effect
- Which lens(es) does it occur with?
- Do you have a filter or hood mounted?

I can't post more pictures right now, mb on Monday. As I guess, the effect mostly appears with Summicron 50/2 of previous version, that one with handel on the distance ring. There's no hood, and Rodenstock protection filter on.
P.S. I'm almost sure that this lens works OK on my M4-2...

I've seen references in the past on the 'net to internal reflections caused by that lens, the 50 with the finger tab. Someone I recall devised some kind of DIY fix with a ring of thin black paper inside the rear of the barrel. I've never heard of it with the latest version which is optically the same.
 
Are you and your friend getting your films done at the same place? That is not in internal reflection. It is a sharply defined area of exposure. Flare, either from the lens or some internal part would be poorly defined at the edges.

I would suggest a test roll taken to a different shop. There is nothing inside a Leica M6 that would cause this.

Dan, we live in different countries🙂 Leica's support engineer supposed it to be "seal is out of order".

Alas, that's not the reason - everything is blackened inside the barrel...
 
Well, if that could be useful to anyone: according to advice of one profi in camera repare, I interchanged backdoors between my m6 and m4-2, up to this moment (3 or 4 films are shot) there is no flare...
 
It is not a light seal. People complain about the current 50 2.0 doing this in pictures AGAINST the light.

The fix is a thin cardboard circle placed behind the rear element. Cut a 2x3 proportion from the circle as large as possible. This leaves very small amounts of paper at the rectangle corners. BLACKEN. BS fix for Leica lenses, but what can I say.

If this doesn`t fix it , have the camera examined for leaks.
 
Why not examine the camera yourself. I found a light leak on my 111f under the shutter counter.

You need a almost dark room and a penlight. Remove the bottom and shine the light all around the body and see if light enters. Pay attention to where the hands go as they sometimes cover leaks causing intermittent problems. OPen the shutter on B and look thru lens opening with the light on the back.

This was the case with mine. The sun only entered from the right and only if my hand did not block it.

This problem has been posted before and the marks you show were traced to the lens design of the last Summicron version 4 , 1987 or newer. The baffle solved the problem. I do not have the lens so I can`t comment from personal experience.
 
2 Ronald M: I'm almost sure that it is light leak now. Espesially because it appears between frames, not in a single one. As I guess that tells that it happens not trough lens at all... I hope I'll find the reason.
 
If between frames, it is not the lens in all cases then. Do the penlight thing in semidark room and also tape over the the back door edges for a roll or two.

Try loading like a screw mount is loaded and you will not have to retape.
Mylar slide binding tape is lightproof and won`t leave residue, but use care with ANY TAPE ON PAINTED SURFACES. You may pull up the paint.
 
You said you cured it by swapping doors? Is the fuzzy seal of the suspect door intact? It's on the right as you look at the open door, so it would be above the sprocket wheel with the door shut. Mind you I'm looking at an M5 for reference, M3 has no such fuzzy business, so I don't know about the '6ttl so I should just shut up.
 
Send it to a reputable Leica repairmen and have him assess the problem. Or maybe it's bad karma....yours or the cameras.
