I purchased a 35-70mm zoom that came on a OM-40 in great condition for the same cost in a lot of sources priced as the lens alone. Fortunately or unfortunately, one gets duplicates of lenses or bodies this way. So, you end up with backups, et al. Still the OM-40 is a neat shooter with the Winder 2. I like the movement of the manual wind in the 1's and 2's, but it seems to be less of a smooth thing in the rest, so I use the Winder 2 to advance the film and put less stress on the manual advance mechanisms. No use pushing the envelop on these 35-year olds. Right now, I'm shooting some BW400CN in an XA and it's neat to see what happens with moving the ASA around. It's got a lot of latitude without reciprocity, so it seems...
