I bought this lens as a stopgap while I waited for the 5D3. _When_ it shoots nice pictures, it's almost L quality, with great color and sharpness. But it's only now and then that it shoots nice pictures. I get a lot of back focusing, and the manual focus ring has such a fine travel you need remarkable haptic skills to pull good focus in video. But then again the video I shot on it a couple weeks ago just became video of the day on a popular site, so its problems aren't gonna prevent success. The OS is good (and not great) for stills but is not good for video, I far prefer the 24-105L's IS which is more the opposite.
This lens is for crop cameras so its life is limited (it fits on ff but I haven't seen what that does...vignettes madly?). As for lens caps falling off, I have a UV protector on it and have no problem with that.
