So recently I bought a couple of m42 lenses and adapter.
I'm a little confused with this this stuff. I thought I had it researched, but turns out there's variants of the Helios 44-4.
Some of these hit the mirror on the 5D Mark II, but there's conflicting info out there. I just want to double check before I mount it which version I have?
Here's the ebay listing:
I have a sneaking suspicion I bought the wrong one.
I'll be using a Fotodiox m42 to EOS mount, if that helps.
