Canon Drop-In Circular Polarizing Filter PL-C 52 (WIII)

The Canon Drop-In Circular Polarizing Filter PL-C 52 (WIII) offers a simple solution for you to use filters with select Canon super-telephoto lenses that do not have filter threads, such as the Canon EF 400mm f/2.8L IS III USM lens, and the Canon EF 600mm f/4L III USM lens. The drop-in holder is easy to install and remove, and the polarizer lens is permanently installed in the unit. 

The circular polarizing filter is useful for minimizing reflections and glare and enhances overall color and tonal saturation by filtering out light that has become polarized due to reflection from a non-metallic surface.
