I have a mint condition Canon 24-105 F4 L IS and would like to trade it for like same condition Canon 24-70 f2.8 L. I found out I need the 2.8 more then the range or IS!
I have a 17 - 40 L which I have only used to take a few test shots when I first received the lens. It, too, is in mint condition. I have simply found that the 17 - 40 range is not to my liking (plus, when I purchased the lens, I aniticpated getting a camera body with a 1.6 cropping affact rather than the 1.3 which I have with my iD Mark II N. Might you be interested in working out some sort of an arrangement in connection with my lens?
