Hello! Just recently began the foray into the legacy lens market. I've already purchased an SMC Takumar 55mm f2 m42 for $10 which I love! However, today I purchased two more legacy lenses for $5 a piece! One was an Auto Kentar 35mm 2.8. Its a bayonet mount, which I thought was a K-mount but it might be an MD or something else! I need help identifying this mount! Also, if anyone could point me in the direction of a review of this lens, it would be very helpful! Secondly, I purchased a Konica Hexanon AR 40mm f1.8. I believe it is an MD! Does anyone know the value on a good copy of this lens? Here are some pictures if you need visual help to figure out what lens it is.
