Camera lens filter Rollei 26238 — Ultraviolet (UV) filter, 77 mm, black/transparent

Rollei 26238 is a 77 mm ultraviolet (UV) camera lens filter with a black mount and transparent glass, designed to reduce ultraviolet light and protect the front element of compatible lenses. Supplied as a single piece, this UV filter is intended for general outdoor photography, landscape and travel use where reduction of UV influence and physical protection of the lens are required. The filter reduces scattered UV components that can cause a blue cast and contributes to clearer images by limiting UV-related chromatic aberration.

Advantages

The Rollei 26238 UV filter provides measurable reduction of ultraviolet light while keeping transmitted visible light largely unaffected, helping maintain natural colour balance. Acting as a protective barrier, the filter guards the front element of a lens against scratches, dust and incidental contact. The filter is described by the manufacturer as equipped with durable glass and a robust mount designed for frequent outdoor use and sustained handling. Luminance coating and scratch-resistant surface treatments are used to minimise reflections, repel water and oil, and preserve image fidelity over extended use.

Suitable for

• Outdoor photography where UV light and haze reduction is beneficial
• Landscape and travel photography to protect the front element during transport and use
• General-purpose lens protection while maintaining neutral colour rendering
• Situations with strong daylight and scattered sky light where blue cast may occur

How to use

Screw the Rollei 26238 UV filter onto the front thread of a compatible 77 mm lens until it is seated securely but not overtightened. Use the filter as the outermost element for general shooting to reduce ultraviolet haze and provide continuous physical protection for the lens. Clean the filter surface with a soft brush or microfiber cloth and an appropriate lens cleaning solution when required; avoid abrasive materials and excessive force when removing or attaching the filter to prevent damage to the filter ring or lens thread.

Usage recommendations

For optimal results in landscape and bright outdoor conditions, keep the UV filter on the lens to reduce potential blue cast from scattered UV light while maintaining colour neutrality. Remove the filter when using certain wide-angle lenses if vignetting or mechanical vignetting occurs, and store the filter in a protective case when not in use to avoid accidental scratches or impacts.
