... When the M6 arrived (80's?) I rushed out an bought one. Like my M4-2 the VF flared badly ...
VF patch flare .. from the second run of the M4-2 and all later bodies up until the early 2000s, Leica was getting comments that people wanted thicker, brighter frame lines and they made a change to achieve that. It also caused a lot of viewfinder flare.
Early M4-2 VF optics are identical to the M4: no flare. They finally created an optical fix for the flare issue in the late model cameras, and the fix can be applied back through the line.
We all have our likes and dislikes. My M4-2 needs a shutter overhaul but is otherwise perfect. My M6TTL 0.85x is perfect. It took me 50-some years to move through the M bodies I've had, and I'm happy with these two film bodies, and the M10-M/-R that I use alongside them. I'm also happy with my Leica IIIc as well, a nice replacement for the IIIf, IIc, and IIf I had all those years ago. Never had an M7, never owned an M5 or an M2, or an MP.
Hmm ... M3, M4, M-P (2x), M6TTL 0.72x, M4-2, M6TTL 0.85x ... seven M film bodies over 55 years. Three CLs too. An M9, an M-P240, an M-D262, and then the current M10-M, M10-R, and my second X2. An SL601. Prior to all of those, a IIIf, a IIf and a IIc. I've certainly given Leica a good bit of my spare change, eh? LOL!
I'm pretty happy with what I have now, just need to use it more.
