A VERY good friend of mine sent me her Yashica. The lens confuses me, though. There are two rings at the front of the lens with an f-stop and then behind that is a dial with the feet/meters and behind THAT is another dial with the f-stop. There's no light meter...but I have a Weston Master II that I can use. It's still accurate, at least it matches what the internal light meter of my Pentax. The lens is a Super Lentar, wide angle, 1:2.8, f=35mm. Any explanation, help is appreciated. Thanks!
