I need a circular polarizer and an ND400 drop-in filter for a Canon 400mm F2.8 IS. I find the price of the Canon filters prohibitive for the moment. I have not been able to find any third party filters for Canon super telephoto lenses. Has anyone seen such a thing?
I would suggest checking with B&H Photo Video in New York City. If any are made, they will have them or at least access to same.
