Hey m8
I saw that you have experiance in converting Topcor lenses to PK mount.
I have recently bought 3 Topcor RE lenses, 35mm 2.8, 5.8cm 1.8, and 135mm 3.5
I did first convert the 5.8cm to a PK mount but without aparture control from the camera.
Its recognised as a 1.7 A lens probably because I used an old experiment PK mount were I had drilled some holes trying to make it recognised as an A lens. It works like a m42 but with a bayonett instead and its a fantastic lens.
Then I tried to convert my 35mm 2.8 but this time I used an old Vivitar PK/A mount and actually got it to control the aparture from camera. However. This PK/A mount is thicker so I dont get infinity.
Most lenses hase some room for adjusting infinity but not this one as far as I can tell.
Have you made any progress in this area?
btw.
I have an aunt and cousin in Melbourne
Happy for any input.
All the best
