Camera lens neutral density filter Rollei 26249, 49 mm, 1 pc, black/transparent

Rollei 26249 is a 49 mm neutral density (ND) camera lens filter supplied as a single piece. The filter reduces incoming light by approximately three stops without altering the colour balance, allowing longer exposures and wider apertures in bright conditions. It is finished with a black titanium ring and a transparent optical surface, and fits lenses with a 49 mm front thread. Typical uses include landscape, motion-blur and portrait photography where controlled exposure and depth-of-field are required.

Advantages

The Rollei ND filter provides even, colour-neutral attenuation of light to extend exposure time while preserving accurate colour reproduction. Its optical glass is treated to resist reflections and surface abrasion, and the temperature-stable black metal ring is designed for reliable mounting and removal in outdoor conditions. Quality control procedures during manufacturing aim to ensure consistent optical performance across individual filters.

Suitable for

• Long-exposure landscape photography
• Creating motion blur for water, clouds or traffic
• Using wider apertures in bright light for shallower depth-of-field
• Studio or on-location portrait work requiring controlled exposure

Key specifications

• Filter type: Neutral Density (ND8), approx. 3 stops light reduction
• Mount diameter: 49 mm screw thread
• Quantity: 1 piece
• Optical surface: transparent, colour-neutral attenuation
• Frame finish: black metal ring designed for outdoor use
• Surface treatment: anti-reflective and scratch-resistant coating

How to use

Screw the filter onto the front thread of a 49 mm lens, ensuring the threads are clean and free of grit before installation. Compose and meter the scene normally; when the filter is fitted, adjust exposure or use a tripod and remote release for long exposures. For motion-blur effects or wider aperture shooting in bright conditions, set the desired aperture or shutter speed and make incremental exposure tests to confirm correct results.

Usage recommendations

Use a sturdy tripod and remote release for exposures longer than a few seconds. Keep the filter threads and optical surfaces clean and store the filter in a protective pouch when not in use to avoid scratches and dust. When photographing in extreme temperatures or wet conditions, ensure the metal ring and glass are dried and checked before removal to prevent thread damage.
