topic Canon 300mm f/2/8L non-IS lens drop-in filter compatibility with IS lenses in EF & RF Lenses https://community.usa.canon.com/t5/EF-RF-Lenses/Canon-300mm-f-2-8L-non-IS-lens-drop-in-filter-compatibility-with/m-p/285301#M13762 <P>Will the drop-in screw-in filter holders for the 300, 400 and 500mm IS lenses fit the older non-IS lenses. The release button is different, but they look similar. I have the gelatin filter holder. I cannot find a screw-in or polarizing filter holder for this older lens.</P> Wed, 30 Oct 2019 00:17:47 GMT DavidBenefiel 2019-10-30T00:17:47Z Canon 300mm f/2/8L non-IS lens drop-in filter compatibility with IS lenses https://community.usa.canon.com/t5/EF-RF-Lenses/Canon-300mm-f-2-8L-non-IS-lens-drop-in-filter-compatibility-with/m-p/285301#M13762 <P>Will the drop-in screw-in filter holders for the 300, 400 and 500mm IS lenses fit the older non-IS lenses.
