I just bought a cheapie FD/FL lens adapter from Amazon, not yet arrived. But in looking over my ancient collection of FD and FL lenses to see if they are worth buying even a cheap adapter for. I'm surprised to see that these lenses aren't much bigger than the lenses for m43s! I have a 200 mm f/4.5 Canon FL lens that is quite petite. I realize that from buying and selling used Canon Camera's in my pre digital days, I have an overabundance of 50mm f/1.8 lenses in both FL and FD mounts Now I'm not ready to sell them, I intend to try to "Cherry pick" the best one,optically, and sell the rest, say, maybe 5 others. Ebay is listing them individually for between $25 and $50. And none of them seem to have any bids on them. PLUS, it's been years since I've used EBay, and for the life of me, I can't seem to figure out how to get to completed auctions to see what similar items sell for. (I'm not signed in, does that make a difference? I'm not a big EBAY fan and don't want to create or reactivate my old account until I'm sure I want to do this) That's quite a spread in price I see with no evidence of any of them likely being sold regardless of price. Are these things worth selling at all? and if so, in your opinion, would it be best to sell them as a unit, or individually? What price do you think they are worth? Is there some other site that would likely tell me what these things are REALLY worth?
