I do not know much about Canon, but I would call the service dept. at Canon and ask, I would bet they will have you send it in and hopefully it's repairable. Is it still under warranty as that would be great they may exchange or repair for next to nothing or free. There are many Canon folks on the site they might know what to do.

The on/off switch for my Canon 100-400 EF-L (series 1) broke off! From the looks of things, this should be a fairly simple repair, possibly even a do-it-yourself at home kind of thing. Does anyone have experience with such repairs? Any thoughts on what a repair like this should cost? Am I recommended to send it out? I live in Alaska, so sending it anywhere is always expensive. The lens is very much outside of warranty, originally purchased in 2010.
