[Leica] LTM to M adapter doesn't quite work

[Mark Kronquist]

I’d just buy a new adapter. I use a slug of them Leica and third party and have not had an issue with Film or Digital M cameras

It's a 28/90 adapter, not encodable, probably Voigtlander, but made before they branded them.  It has worked well on my previous Leicas, both film and digital. It was always a little more reluctant to click into place than my other LTM/M adapters, and I think that may be the problem.

And when I try to take a shot or go into LIve View, the camera's LDC screen tells me that no lens is mounted.  I've also seen a message in the viewfinder that looks like "bc."

Can anyone point me to the place to file, or an article that describes it?   And would  be advisable, or should I just spring for a new adapter to avoid messing something up in the camera?
