I like the MC 35~70mm zoom, the MC lenses are more compact than the ML lenses. There are two versions of the DSB 28mm, one with a 55mm (or 52mm?) filter thread, and one with a 58mm filter thread. I found the small version to be a OK if a little cheap, but the rare (and quite expensive) larger version is a very good, well built lens, if you can find one. I regret selling mine. The only real differences between the Super 2000 and the original FX 3 are a faster shutter on the former and a meter switch on the latter that is separate from the shutter button.
