Hello,

Please can someone help me to identify these lenses (mount type)? I'm planning on using them on my Sony A-57 with a converter ring.

What do you think of these lenses? Are there any good? Check this link for lens mount and names.

Many thank you for your feedback

I've not got my mount illustrations to hand, so can't advice on the mount.
It's not PKA as it has one of the linkages missing.
CZJ lenses are pretty good but not upto the West German Zeiss standard.

I suspect if you try a general photography forum rather than a Pentax specific one You'll have more help on this. The Manual focus forum (forum.mflenses.com) would be a excellent choice.

I think it might be a Practica B mount. Google it and compare.

Also see http://vintage-camera-lenses.com/praktica-b-mount-adapter/

While similar, it isn't a Pentax K mount.

Definitely Pratica (B?) but not PB mount which has same contacts as B mount but no shield against the aperture lever.
