39mm Neutral Density Filter for DSLR Photographers

The B+W Master 802M reduces light by two f-stops with a .6 density rating. It fits lenses with a 39mm thread and works with both analog and digital cameras. Photographers gain creative control over aperture and shutter speed without altering natural colour balance.

Consistent Light Reduction Under Extended Use

The colour-neutral glass maintains accurate hues during long exposures such as 1/15 sec shots that create cotton-candy water effects. Multi-layer anti-reflective coating with seven layers per side suppresses flare and ghosting when shooting into bright light. The thin-film technology delivers stable density across the frame during sustained outdoor sessions.

Simple Thread-On Installation

The filter screws directly onto the 39mm front thread of compatible lenses without adapters. Brass mounting rings resist binding and allow easy removal even after temperature changes. Dirt- and water-repellent nano coating simplifies cleaning, while the slim profile prevents vignetting on wide-angle glass.

Questions about this item

Does the 39 mm Master 802M ND 0.6 filter heat up or draw power during all-day long exposures?

No, this is a passive glass filter with no electronics, so it generates no heat and consumes no power regardless of how long you shoot.

What must my lens already have for this 39 mm filter to mount and work?

Your lens needs a 39 mm front filter thread; the filter simply screws onto that thread and requires no batteries, adapters or firmware.

Will the 0.6 density (two-stop) reduction shift colour balance on my older manual-focus lenses?

The filter is colour-neutral by design, so it preserves natural hues on any lens — vintage or modern — without introducing a colour cast.
