After picking up a little 139Q I was thinking of getting the 45/2.8 Tessar, but even used they are going for $120 to $180 USD used. That seems a little too much to me. Instead I was thinking that a Yashica 50/2 or 50/1.9 might be a great compromise. They are dirt cheap and a stop faster which will make for a brighter focusing screen. I have a CZ 50/1.4 but at times it's more lens in terms of weight and length than I want to carry. Anyone care to share their thoughts on the Yashica ML 50's?
