I finally got around to getting a Zeiss 50 1.7 MM for the body that garageboy kindly sent me.
However it looks as though lens, whilst working fine in Av and M, is broken as the camera won't switch into P or Tv modes. There's a lug on the outside of the lens that looks broken, and I think this needs to engage with a switch on the outside of the lens mount ?
Is this a common thing for the MM lug to be broken ? Any easy home fixes ?
