I'm gonna be buying a used lens (a manual fast 50) sometime soon from a local used camera dealer. What things should I be looking for in buying a used lens? Personally I'd like to try the lens out mounted on my camera but I don't really know the store's policy with that so what else can I try?
Thanks!
if you're buying the lens from a "local used camera dealer", I would absolutely think without a doubt he will let you mount the lens and try it out in the store. If his answer is NO to this request, I would politely say thank you and turn towards the nearest exit.
I have purchased a pretty fair amount of lenses for a beginner... my "worst" purchases were through EBAY; I "won" 2 lenses, each works properly but each also have slight issues which I would need to list if I were to sell them. My best bargain purchases were through Craigslist, I once snagged a Pentax F 50/1.7 and an A 50/2.0 with bodies for $20. The great thing about Craigslist and other local outlets is the ability to see, touch and try out the lens. With that said, I have, however, purchased items at the Pentax Forums Market Place with success.
What to look for? Personally, I need to make sure the lens can focus sharply/properly (focusing ring is smooth and snug v too loose) and if it's a k-mount v. screw mount, the blades must be able to stop down and be, how do they say it on Ebay, "snappy". Some minor scratches on the front element is usually OK but on the rear element NOT. Look carefully at lens in good light and if you see some spidering/web on the glass, I would not buy it...
And before you buy it, standing in line with cash in hand, you got to ask yourself,
Do I really need it? My answer has always been
yes... have a good time
