Tiffen 305ND6 30.5mm Neutral Density 0.6 Filter

The Tiffen 305ND6 is a 30.5mm Neutral Density 0.6 filter that reduces the amount of light reaching your camera sensor by exactly 2 stops. This allows photographers and videographers to use wider apertures for shallower depth-of-field or slower shutter speeds for motion-blur effects, even in bright outdoor conditions where the scene would otherwise be overexposed. Unlike colored filters, a neutral density filter is designed to affect all wavelengths of light equally, preserving the natural color balance of the scene.

Built using Tiffen's proprietary ColorCore technology, the filter consists of a light-absorbing material laminated between two pieces of optical glass. This construction method provides consistent, even density across the entire surface of the filter and ensures long-term durability against delamination or coating degradation. The 30.5mm size is a niche thread diameter, typically found on compact cameras, smaller video cameras, and select specialty lenses, so it is important to verify lens compatibility before purchasing.
