Wrong frame brought by Voigtlander LTM to M bayonnet adapter

[edodo]

I have a 50/75mm LTM to M adapter by voigtlander that bring only the 35mm frame line on my camera. I am sure that my camera is not wrong as I have other lenses.

Does anyone know why is this adapter bring the 35mm frame, and if other cosina adapter will do the same? I need a 50mm frame line adapter to use my collapsible fed and collapsible cron. Thanks.

what camera are you using and what lens?

The lug that moves the feeler arm may have been filed down. The 35mm frame is the "home" position for the frame selection mechanism. I had one CV adapter that didn't lock into place, so bad ones do exist.

Like mark says, the 35 ist the default position on a M6/M7/MP. Its possible to file down a 50/75 adapter or mount to work as a 35/135 (I did that on the 40 Nokton), but not the other way round. Yours must be faulty or has been filed down by a former owner (if bought second-hand).

I bought it second hand here in the classified, the seller told me it was like that when he bought it and that he did not filled anything. Then he redirected me to his vendor photovillage or robert White i don't recall exactly to get more info wich I didn't. The seller was using it with bessa r2 or the likes so it wasn't an issue for him. As I use a M4, it is for me. I wanted to use a collapsible summicron and a fed elmar on that wetzlar body... I may just sell the leica 35mm adapter that I bought at the same time and get a proper 50mm adapter because I can keep the faulty adapter to use with my jupiter 12. But I like the genuine one because it is geguine.
