Before I send it to Canon for repair I would like to ask if this wobble of the "baffle" is normal and I never noticed it, or is it likely the result of the drop. Photographically the lense appears to be work fine. Can anyone confirm that this wobble is normal or not?</P> Tue, 22 Jul 2025 13:33:46 GMT Howie1223 2025-07-22T13:33:46Z https://community.usa.canon.com/t5/EF-RF-Lenses/RF100-500mm-F4-5-7-1-L-IS-USM-internal-baffle-wobbling-after/m-p/561043#M38131 <P>Hi - I noticed when visualy examining my RF 100-500 lens after an unfortunate drop, that as I look down the barrel I see what I think is a internal cylindrical baffle, and it wobbles slightly as I rortate the lens..
