Hi All I have recently bought a second hand lens to play with, however I have difficulty identifying the mount of this lens, can someone please help me with this? And if you can also recommend me an adapter to use on my m4/3 camera , it would be great! Photos of the lens are attached in this thread. (Model PK-A/R97033481, is it a hint telling me it is a PK-A mount? If so, what is PK-A mount exactly? is it same as PK? what adapter should I buy to use on my m4/3 camera please?) Thanks in advance!
