So like the title implies, I'm thinking about buying a used lens from B&H, but I'm not sure whether it's a good idea or not. Is the site good to buy used lenses from? Or is it just not worth taking the risk? (it's ~$100 off the regular price)
Interesting, how did your oly come with the 17.5 instead of the 14mm?
I agree with the above poster, if it's used go see it yourself and try it on your camera. Otherwise buy new, the four thirds lenses aren't as bad as some of the others when it comes to pricing.
Which lens are you looking for?
