My lens preferences seem to have come full circle, and I've returned to a 50mm as my standard after some years of wide angle mainstays. My criteria is the lens has to be reasonably light and compact, resolution good or better, and not subject to inflated prices. The three which deliver best are Nikon 50mm F2, Yashica ML 50mm F2, Canon FD F1.4. It's difficult to choose a winner as each have different characteristics. Any lenses I've missed out that I should try?
