Canon Drop-In Circular Polarizing Filter

This filter is specifically designed for the Canon Drop-In Filter Mount Adapter EF-EOS R. It is intended for use when mounting EF or EF-S lenses onto Canon EOS R-series mirrorless cameras.

Yes, you can, but this drop-in filter is primarily designed to provide polarization for lenses that lack front threads or to allow you to use a single filter across multiple lenses without needing different sizes for each.

The filter features an integrated rotation wheel on the side of the drop-in holder. You can simply turn this wheel while looking through your viewfinder or at your LCD screen to dial in the desired level of polarization.

This filter excels at cutting glare and reflections from non-metallic surfaces like water or glass. It also deepens the saturation of blue skies and foliage while reducing atmospheric haze in distant landscape shots.

Because it is a circular polarizer, it is designed to work with your camera's autofocus and metering systems without causing the errors often associated with linear polarizers. However, keep in mind that it will reduce the amount of light entering the lens by about 1 to 2 stops, which may require a slight adjustment to your exposure settings.
