Neutral density camera filter Hama ND2-400 49 mm

The Hama Neutral Density (ND2-400) 49 mm filter reduces the amount of light entering the lens without changing colour balance, enabling longer exposures and the use of wider apertures in bright conditions. Made from high-quality optical glass with a durable black metal mount and a rotatable front element, this 49 mm filter suits lenses with a matching filter thread and is compatible with digital, film, system and video cameras. It also provides an additional protective layer for the front element of your lens.

Advantages

This variable ND filter lets you control exposure by extending shutter speeds between approximately +1 and +8 stops (ND2–ND400) while maintaining natural colour rendering. The rotatable front mount allows fine tuning of light reduction. Built from high-quality lens glass with single-layer coatings on each side, the filter reduces stray light and helps protect the lens surface from dust, fingerprints and scratches.

Suitable for

• Landscape long-exposure photography (waterfalls, rivers, seascapes)
• Portraits in bright sunlight using wide apertures for shallow depth of field
• Creative motion blur and impressionistic effects
• Protecting the front element of lenses with a 49 mm filter thread

How to use

Screw the filter onto a lens with a 49 mm filter thread. Rotate the front element to change the density until the exposure or aperture reaches the desired value; use a light meter or camera exposure preview to confirm settings. For long exposures, use a tripod and, if available, a cable release or camera timer to minimise camera shake. When shooting moving water, exposure times longer than about 1/30 s will produce a smooth, flowing effect.

Usage recommendations

Store the filter in its case when not in use and clean with a soft microfiber cloth or lens cleaning solution to preserve coatings. Avoid excessive tightening on the lens thread to prevent damage. For consistent colour and image quality, check exposure and white balance when changing density settings.
