ASI 120MC - non-standard c-mount thread pitch

sgazer

hi all,

I've just received my new ASI 120MC camera and I'm very pleased with it. One thing I noticed though is the T-thread to c-mount adapter seems to have a non-standard thread pitch. I have several c-mount lenses, a Canon EOS adapter and c-cs spaces and whilst the c-mount adapter is the correct diameter, it seems to have a different thread pitch as my lenses, adapter and spacers bind after engaging 1-2 threads.

This seems bizarre, has anyone else found this? cheers

I think it maybe a little tight for some other C or CS lens

our lens is CS adatper too and it can fit inside

thank you for your reply. It definitely seems to bind the threads. When I try your C-mount lens, it fits the ASI camera fine, but doesn't fit my CS spacers, Mintron, Samsung or LN-300-11673 cameras!

Weird!
