Good adapter in lens accessories

Well done. I bought it to adapt m42 mount lenses to the Sony A7ii. This adapter has an inner flange for pushing the bezel pin, which allows you to move to the bezel. Some (not all) lenses require this, otherwise the lens would stay wide open all the time.

Pros
  • Beautiful
Cons
  • Disappearing

  • Brilliantly done
Cons
  • Hard to say
