Lens filters protect your glass and control light before it hits the sensor. Circular polarizers cut reflections and glare off water, glass, and foliage, while neutral density filters cut light for long exposures without shifting colour. UV filters are just clear glass for everyday lens protection, and black diffusion filters soften highlights and skin tones for a subtle cinematic look. Filters are sized to your lens's thread diameter, so check your lens before you buy.
