Martyn,
You might want to run a film before condemning the lens for haze. I bought a
Vivitar brand but Kiron-made 28-85/2.8-3.8 lens a couple years ago that had
sticky a diaphragm, but when it came it also had a hazy rear element. Since
the postage was about equal to the price (cheap), I didn't bother to return
it. When I cleaned eveything up, the element with the haze was permanently
damaged (still somewhat hazy). With that element near the rear, I didn't
think it would perform so well. However, I ran some test shots on E100VS
against 3 other zooms I had in the same general range, one of which was a
Zuiko. I could not see any discernable difference, either with loupe or
projected.
Since you likely bought the camera as much for fun and nostalgia, rather
than use, I'd suggest you run a film, using the shutter speeds that might
sound about right, and judge from the results on film. You might be
surprised (either how good it is or how bad :-)
