Tiffen 405F3 40.5mm Fog 3 Filter Lens

The Tiffen 40.5mm Fog 3 Filter is a creative lens filter designed to simulate the look of natural fog in your photographs and video. By dramatically lowering contrast and adding a soft, glowing quality to highlights, the filter creates an ethereal, dreamlike atmosphere that is difficult to replicate convincingly in post-processing. The "3" density rating places this filter on the stronger end of Tiffen's fog range, producing a clearly visible effect that softens the overall mood of a scene while still retaining underlying sharpness in the subject.

Built with Tiffen's ColorCore technology, the fog effect is embedded within the glass itself rather than applied as a surface coating. This means the filtration is uniform across the entire frame, with no hot spots or uneven diffusion. The 40.5mm thread size makes it a fit for various compact, mirrorless, and smaller-format lenses. For filmmakers and photographers working in genres like portraiture, wedding photography, and cinematic storytelling, the Fog 3 filter offers a practical way to achieve a polished, in-camera look without relying on software filters after the fact.
