Hello again,

just an another question - on the same shelf with Sigma I noticed an M42 Beroflex 135/2.8, very cheap - about $25 or something. I don't know anything about Beroflex - but again, the lens makes a very good impression by its looks and glass quality. Do you know anything what was the Beroflex company, and what in particular is this lens? I love fast 135 lenses for portraits, maybe this one will enhance my collection?

Cheers,
Zhenya
