Tiffen 55SKY 55mm SKY 1-A Camera Filter

The Tiffen 55mm SKY 1-A filter is a general-purpose optical filter designed to improve image quality by absorbing approximately half of the ultraviolet light that can cause haze and reduce contrast in outdoor photographs. Unlike a plain UV filter, the SKY 1-A features a subtle pink tint that adds a touch of warmth to images, which can be particularly flattering for skin tones, golden-hour landscapes, and scenes shot under overcast or bluish daylight conditions. The multi-coated glass helps minimize reflections and flare that can occur when shooting toward bright light sources.

With a 55mm thread size, this filter screws directly onto any compatible lens and is thin enough to avoid vignetting on most standard and telephoto focal lengths. Tiffen recommends keeping it on the lens at all times, where it serves as a first line of physical defense against dust, fingerprints, and minor impacts that might otherwise reach the front element. Manufactured in the USA, the SKY 1-A sits in the practical, everyday-use tier of Tiffen's filter lineup — an affordable accessory that provides both image enhancement and lens protection in a single piece of glass.
