EF 100-400 tripod mount ring

Hello all,

I want to ask, where i can find a brand new or even used but genuine 100-400 lens tripod mount? i have it with my lens but i a friend [Unfortunately] borrowed the lens from me then lost that mount ring and i feel he will never find it, so i was thinking to buy another one if i can find it anywhere, and still i prefer to get brand new original Canon one if possible.

It's the same Tripod Ring B (W) used on the 70-200 2.8 IS and the 300 f/4 IS among other lenses. Check Amazon. Or call your "local" Canon office and ask for the parts department.

Thanks!

Can you please delete this thread? my friend called me and told me that he found my lens tripod mount ring, so i don't need to buy one so far, if i waited a bit then i will not start this thread, so now it is no point to keep it.
