Tiffen 55DF4 55mm Double Fog 4 Filter

The Tiffen 55mm Double Fog 4 Filter is a specialty effects filter designed to simulate a heavy natural fog look directly in-camera. By softening the image and significantly reducing contrast, it wraps scenes in an ethereal haze that works particularly well for portrait photography, misty landscape compositions, and cinematic video work. The "double fog" design scatters light more evenly than a standard fog filter, producing a denser, more uniform softening across the frame while still retaining the general shapes and forms of your subject.

With a density rating of 4, this is one of the stronger fog filters in Tiffen's lineup, so it's best suited for situations where a bold, unmistakable atmospheric effect is desired. It threads onto any 55mm lens and maintains Tiffen's reputation for consistent optical quality. For photographers and videographers who want to achieve a vintage, dreamlike quality without relying on post-production filters, the Double Fog 4 offers a practical, repeatable solution that works in real time through the viewfinder.
