I'm with Ian. Hard to say from a direct angle, but the flange on the lower right is common to K lenses. _________________ http://www.youtube.com/user/hancockDavidM |

It certainly looks like Pentax K - the lever and its shield is classic Pentax - but I'm not sure. An OEM Pentax lens has a circular slot and lever on the opposite side to the lever (from 9 oclock to 12 in this picture). I wonder if it's from another manufacturer that uses the K mount, for instance Ricoh or Chinon. _________________ Peter - Moderator |

Looks like K to me, the bayonet tab + locking groove + aperture lever all match my Pentax M's locations. |

Further to this, here is a diagram of the early Pentax K and M mounts, courtesy of Bojidar Dimitrov's Pentax K-Mount Web Page http://tinyurl.com/ccmvcrk
The lens in the picture has the diaphragm actuating lever and shield, on the right hand side of the K/M lenses in the diagram, so it is an auto diaphragm lens allowing wide-open focussing, and not one of the earlier manual diaphragm K lenses (at top right). However, there appears to be no slot on the opposite side, with the stop-down indicator, which is how the lens communicates the aperture setting to the camera for wide-open metering, so it looks as though this lens was intended for a camera without wide-open metering or AE.
I could be wrong, but I don't believe Pentax ever made any K mount lenses or cameras like this. They were making M42 lenses for AE long before the K mount was introduced. It makes me wonder if this might be a Russian K mount lens for a Zenit camera. _________________ Peter - Moderator |
