And just to be doubly clear, my "best" comment extended solely to the glass I own.
F-Mount. All 3 lenses are 1986 at the very latest, likely earlier. Since all are AI-S, they're post-1977:
Nikkor AI-S MF 50mm/f1.8. Haven't used it in ages & focus ring is a little graunchy. Might be worth it to get it looked at.
Zoom-Nikkor AI-S MF 28-85mm/f3.5-4.5. Back in my film days it was the only lens on the camera (still on it, too). Still think it's the best glass in this particular stable.
Sigma Zoom AI-S MF 80-200mm/f4.5-5.6. Never shot enough film with this to get an idea of quality. Does have a hard case, though.
Oly 4/3 (original 4/3, not Micro). 2.0x crop factor, purchased Xmas 1995.
Zuiko Digital 14-45mm/f3.5-5.6. POS kit lens that came with the E500. If you can brain a crow with it at 20 paces it's served a purpose.
Zuiko Digital 14-54mm/f2.8-3.5. Upgrade for the kit lens, one of the better-regarded lenses in the original 4/3 rollout. Walkabout lens.
Zuiko Digital 40-150mm/f3.5-4.5. Kit lens, but way better than the 14-45. Best reviews said it didn't suck.
If I go Nikon FF I've got 3 lenses ready to go with compatibility and MF doesn't scare me. The Oly investment is a dead end and if I do go Nikon I'll give the lot to the daughter as an expendable training camera/lens package.
