Anyone ever have a lens release button fall off. I pulled my 1D out of my camera bag this morning and noticed it was gone. I still had the spring and the button but I couldn't get it to reattach. There's a hole and I tried to stick a small allen wrench to manually trigger it, but no luck. I can also hear a rattling when I move the camera. I'm assuming it is off to Canon Repair unless anyone has an great ideas. Anyone had this happen and what did Canon charge you?

best take the battery out asap, in case whatever is rattling around in there is metallic and shorts out one of the several circuitboards, which would probably result in more expensive repairs.

I'd say Canon techs would likely fix this sort of thing in less than 30 minutes.

the closest thing I've got to a shot of the mechanism is this:

The release button/spring is mounted to the front case and somehow hooks the leafspring (arrowed) outwards.

I'd hazard a guess and say the release button had some sort of circlip arrangement to hold it in and it's probably this bit that's either fallen, or broken off.

some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:

here 'ya go, parts manual for 1D MK II

http://www.strappe.com …S_1DMII_Parts_C​atalog.pdf (external link)

looks like the button has a hook clip that is screwed to it...

see page 8. The hook itself doesn't have a partnumber so hopefully can be retreieved from inside your camera - preferably before it does some damage...

Thanks joeseph. I ended up just sending it in to Canon. In case anyone comes across this thread is a search it just shipped out so it took them about and week and it was $330.00 plus my shipping there so around $370.00.

Wow, thats alot, I could have done it in 15mins, the actual mechanism is a simple L shaped lever with the pin that is pushed into the lens hole by a spring, could'v walked you through it, oh well, hope it all comes back safe and sound
