The Nikon C-PL405 is the drop-in circular polarizing filter for specific Nikon super telephoto lenses. Key features include:
- Specific Compatibility. The C-PL405 is only compatible with the latest generation Nikon 400mm f/2.8, 500mm f/4, and 600mm f/4 superteles.
- Why Use It. Circular polarizers help to reduce reflections and glare from just about any non-metallic surface (think water, glass, electronic screens). They’ll clear up haze when shooting subjects at a great distance, all with a minimal drop in autofocus performance.
- How to Use. Just remove the drop-in UV filter near the lens mount, then replace it with this one. There’s a dial on the top of the filter holder that’s used to adjust polarization.
- Filter Factor. Do keep in mind the this filter has a filter factor of 2-4×. This means reduced exposures by 1-2 stops.
