The optical construction or equation requires a glass filter in place; either the Gelatin 52, a 52mm screw-in filter or the POL filter solution. There should be absolutely no performance difference using the Gelatin or a 52mm filter which has slightly wider diameter than the Gelatin filter and is positioned with a slight off-set compared to the Gelatin filter.

I am actually not so impressed with the Canon filters and I use the best HOYA or B&W filters. I have not tested the different filters on any of my white primes, but I have the best results with HOYA PRO1 Digital Filter, HOYA PROND and their best POL filter in front of primes and zooms. Especially the old 100-400L I is very sensitive to bad filters, which makes it a great test bench.

I usually use either a POL filter or a HOYA ND8 filter in my 200L f/2 as I prefer to use it wide open if at all possible.

Thank you. And may I ask which of the filters you mentioned do not in any way change exposure or add any level of filtering? The 0 lens you mentioned indicates it cut UV. I did not want to introduce anything in the path of the lens or sensor.

Thank you.
