Camera lens filter Rollei 26239 — Ultraviolet (UV) filter, 82 mm

Rollei 26239 is an Ultraviolet (UV) camera lens filter with an 82 mm thread size designed to reduce UV haze and protect the front element of compatible lenses. The filter is supplied as a single piece, has a black titanium-coloured ring and transparent optical glass. It fits lenses that accept 82 mm filters and is suitable for landscape, outdoor and travel photography where UV light and scattered blue cast can affect image clarity and colour neutrality.

Advantages

This Rollei UV filter reduces the influence of ultraviolet radiation that causes blue colour casts and a loss of sharpness in distant subjects. In addition to limiting UV transmission it serves as a protective barrier for the front lens element, helping to prevent scratches, dirt and impact damage from reaching the lens surface. The filter is produced with reinforced optical glass and a robust metal filter ring, and features surface treatments that repel water, oil and persistent grime while maintaining colour fidelity and low reflectance.

Suitable for

• Landscape photography to reduce atmospheric blue cast and improve distant clarity
• Outdoor and travel photography where lens protection is required
• Everyday use as a protective front element cover during shooting and transport

How to use

Screw the Rollei 26239 UV filter onto the front thread of any lens that accepts 82 mm filters until it seats securely but not overtightened. Use the filter when shooting in bright outdoor conditions, at high altitudes, or on hazy days to reduce UV-related blue cast and improve perceived sharpness in distant subjects. When not in use, store the filter in a protective case to avoid unnecessary scratches; if the filter becomes dirty, clean it with a blower, soft brush and a microfiber cloth or lens cleaning solution following standard lens care procedures.

Usage recommendations

Use this UV filter as a lightweight, permanently mounted protective layer on premium lenses to preserve the front element. For critical colour work or multi-filter setups, check exposure and white balance after fitting the filter to ensure colour neutrality. Remove and inspect the filter periodically for scratches or contamination that might affect image quality.
