Hello! I've a chance to buy a Yashica FX-103, but it comes equipped with a Vivitar 57-205 1:3,8 lens. I think I like the camera, but I'm not sure about the lens. I alreday have (well, it does not belong to me, but the man who owns it does not use it) a Solingor 70- 210 1:5,6 lens. I'd like to know ir any of You can tell me anything about this Vivitar lens. Is it good/not so good? Becaurs I'd more like to get the Carl Zeiss 50 1:1,4 Thanks!
