Yesterday on a lark I stopped by a pawn shop, of a chain that I've had decent luck with at other locations. They had a Canon EF-M 55-200mm f/4.5-6.3 lens for $65. Returned today with the M100, it works just fine, AF and IS are good. Thing is tiny. I suspect they either didn't know what it was, or they had no way to test it so they just gave very little for it and consequently marked it low. I was surprised, most of the time I've found pawn shops to be pretty savvy when it comes to figuring out market value for what they have, but camera equipment seems to be much less consistent. My wife's camera bag was looking kind of empty, with only the 14-45mm and the 22mm prime. It looks more right now.
