hello NG, this is my first topic here
anyone can guess that what lense they are
The rabbit ears with holes indicate it's two AI/Ais or AI-converted lenses
The position of the AI coupling ridge is at the 8+2/3 position , so these lenses are either f:1.8 or f:2 lenses max aperture
Max aperture of 1.8 or 2 leaves us with a 50mm as the most probable choice for both lenses
The lens on the R has three screws, so it's possibly the 50mm/1.8 AIS produced around 1982
The lens on the L has five screws, so it's possibly the 50mm/2 AIS produced around 1977
What did I win, a cigar?
Ciao from Massimo
