On the B&H site this is what comes (among other things) with the Canon 300mm f2.8L IS : ... "Drop-In Gelatine Filter Holder" which I presume would hold a drop in gelatine filter.
I bought mine in Canada and that's what it came with as well. When you took the filter holder out did it reveal a 52mm glass screw-in filter? If your lens is older and of the non IS type then it would have taken 39mm screw in filter (like my old Nikkor 300), and THAT may well have been standard at that time. If it isn't a screw-in filter then I'd suggest that you are looking at a gel not a glass filter.

I Stand corrected - i tapped it and it sounded like Glass

!!! Does anyone know if I'd need a slim UV filter or will the regular width filter work?
