The all-new EF 70-200mm f/2.8L IS II USM increases the speed, performance and optical quality of the EF 70-200 f/2.8L IS USM. Genuine Canon factory service. I dropped my Canon 70-200 F/2.8L (non-IS). Although it seems to focus accurately and the optics seem fine, the zoom ring is stuck. The outer zoom grip is broken. Canon at first wanted $273 to repair the lens, then changed its mind and wanted $1,200. I tried to explain that cost is more than the lens is worth and that I could buy one in better condition for less money than the repair cost. They would not budge and would not repair just the zoom ring. So, I have the lens back now and have decided to open it up and try to do as much of the work as possible. Can someone recommend a YouTube or other video, Web site or other source of do-it-yourself Canon 70-200 repair information? After opening it up, I see no damage to anything except the beige outer housing that contains the AF/Manual switch and that damage is not enough to render the lens unusable. Even after I removed the zoom barrel, it would only turn, maybe, an eighth of a cycle. I need to go back now and figure out how to get at the two-piece gear mechanism and see if I could, order a new gear assembly and get this working again. Of course, I will probably need to order a ribbon cable or two (pulled a couple loose in the disassembly), a screw (lost) and figure out where the ribbon cables re-attach. I will also consider selling it for parts. ![]() Optically and in AF, it is excellent. Assuming you haven't found these already. Canon 70 200 Refurbished1 - the parts manual isn't a step-by-step service manual, but it's 'exploded views' and part # ID is very helpful. 2 - This brave soul has documented his disassembly of the EF 70-200 f/2.8L: There are a couple time-lapse videos on youtube of disassembly/reassembly of 70-200 f/2.8L and IS, but they go by too quickly to be a good DIY guide.
