I have an EF 100mm L f2.8 IS macro lens that I am considering selling. It was on my 60D when it was stolen 1½ years ago, and when the police recovered it, the hood was no longer attached. I don't use it, and I still have and love my 60mm f2.8, so it's really just been doing nothing. Considering that it was out of my hands for 6 months, it is still in very good shape, with just a slight crack in the plastic window over the distance dial that was there when it was returned. It works perfectly, no damage to any of the optics or electronics, has both caps.
I'm at something of a loss trying to decide what sort of a price to put on it. I see one on Ebay - mint condition with hood and pouch for $879 from Hong Kong. What I wonder is, how much are the hood, pouch, and box really worth? I don't want to undervalue it or make someone think that they are getting stolen goods just because I don't have the accessories. The lens is registered with Canon.
