B and W Filter 37MM ND 3.0-1,000X MRC (110M)

The B+W 37mm ND 3.0-1000x MRC (110M) is a premium neutral density filter designed to reduce the amount of light entering the lens by 10 stops. This dramatic light reduction gives photographers and video creators greater creative control in bright conditions, making it easier to use slower shutter speeds for motion blur effects or wider apertures for shallow depth of field without overexposing the image.

Compatible With

• Lenses with 37mm front filter threads

Key Features

This filter belongs to B+W's respected ND filter lineup and uses a 3.0 density rating, equivalent to a 1000x light reduction. It is especially useful for photographing waterfalls, rivers, clouds, city scenes, and seascapes where long exposures can transform movement into smooth, artistic textures. It can also help maintain cinematic shutter speeds for video in bright daylight when paired with cameras that use lenses featuring a 37mm filter thread.

B+W MRC Coating Benefits

The Multi-Resistant Coating (MRC) is one of the major advantages of this filter. It helps minimize flare and ghosting caused by internal reflections while also making the filter surface easier to clean. Water droplets, fingerprints, dust, and smudges are less likely to cling stubbornly to the glass, which is especially helpful for outdoor landscape and travel photography.

Image Quality and Performance

A good neutral density filter should darken the image without introducing unwanted color shifts or reducing sharpness. The B+W 110M series is known for maintaining strong optical performance while delivering substantial exposure reduction. For photographers working with high-resolution cameras or compact systems using 37mm-threaded lenses, this filter offers a practical way to expand creative exposure options while preserving image detail.

Practical Uses

With a 10-stop ND filter, you can lengthen shutter speeds from fractions of a second into several seconds or even minutes depending on ambient light. This makes the filter especially effective for smoothing water, blurring crowds, streaking clouds, or reducing visual clutter in urban scenes. It is also useful when shooting at wide apertures in strong daylight, allowing more control over depth of field without forcing shutter speeds beyond camera limits.

Build Quality

B+W filters are widely recognized for durable construction and precision manufacturing. The 110M filter is designed for photographers who want dependable performance and a secure fit. Its quality glass and coating technology make it a strong option for regular field use, whether for landscapes, architecture, travel, or experimental long-exposure work.

How It Compares

Compared with lighter ND filters such as 3-stop or 6-stop models, a 10-stop ND filter is much better suited to dramatic long-exposure effects in daylight. Compared with variable ND filters, this fixed-density filter offers a single strong reduction level without the potential variability or cross-pattern artifacts that can appear in some variable designs. For photographers who specifically want maximum long-exposure potential, the ND 3.0 remains a popular and effective choice.

Usage Tips

For best results, compose and focus before attaching the filter if your camera struggles to autofocus through very dark filtration. A tripod is strongly recommended, along with either a remote release or self-timer to reduce camera shake. Covering the viewfinder on DSLR cameras during very long exposures can also help prevent stray light from affecting exposure accuracy. Testing exposure times and using bulb mode may be helpful in brighter scenes.

Recommended Accessories

Useful companions for this filter include a sturdy tripod, a remote shutter release, a lens cleaning cloth, a protective filter pouch, and long-exposure planning tools such as an exposure calculator app. Photographers shooting landscapes may also pair it with a circular polarizer or graduated ND filter system, depending on the lens and shooting setup.

Why Choose This Filter

The B+W 37mm ND 3.0-1000x MRC (110M) is a strong choice for creators who want premium optical quality, excellent coating performance, and the creative flexibility of a true 10-stop neutral density filter. Its compact 37mm size makes it particularly suitable for smaller lenses while still delivering the same dramatic exposure control valued by serious photographers.
