won this for a few quid on the bay, Practicar/Pentagon 35 - 70, not a Contax or Pentax PK mount, can anyone help, sorry for fuzzy pic which doesnt seem to upload, looks like Pentax pk has 3 contacts to rear[/img]

Wild guess based on info above: Praktica B-mount (PB-mount)

As above, there is a 99% chance that it is a Praktica PB mount lens. There were a small number made in M42 screw mount if not.

Mamiya (Z)E would be another example of a metal mount with three contact pins - it is less Pentax K like though, and the later lenses have a ten-pin contact set.

Oops, I missed the three contacts bit. It's definitely a Praktica PB mount lens. This will work nicely on a Nex or micro 4/3rds camera.
