I'm selling a Canon EF-S 10-22mm f/3.5-4.5 USM wide angle lens. I'd be happy to trade it for an Olympus 9-18 plus 150.00, or I will sell it for $650.00. I'd also be interested in trading it for an Oly 12mm . . . I'm also selling my old Canon 20D and a Tamron 28-75 f2.8 zoom lens. Both camera and lens are in excellent shape. Together for: $700.00; separately for 380.00 and 375.00. I'm posting some photos below. Thanks for looking!
