Just got a hold of an OM-30 (F)... with the autofocus zoom it was made for, it's an interesting sequence of model. The lens looks well made and it's supposed to work on all the single bodies. And with the M-cord, the winder 2, and a normal non-auto focus lens attached, it's a real trip in the OM size, albeit heavy. But we're talking tech 30 years ago. Neat, though. -Bob G.
