Variable density camera filter B+W 1072522, 77 mm, MRC coated

B+W 1072522 is a 77 mm variable density (ND) camera filter with Multi Resistant Coating (MRC) designed to give photographers adjustable control over incoming light. The XS-Pro Vario mount provides a convenient indexed control to set density between approximately +1 and +5 stops, enabling longer exposures or wider apertures in bright conditions. The filter is supplied as a single black unit that threads onto lenses with a 77 mm filter thread and is suitable for landscape, portrait and creative photography where variable light reduction is required.

Advantages

The variable density mechanism lets you fine-tune exposure without changing lenses or stacking multiple fixed ND filters. MRC (Multi Resistant Coating) reduces reflections and improves light transmission for more accurate colours and contrast. The XS-Pro EW (extra-wide) mount design is intended to reduce the risk of vignetting on wide-angle lenses and the indexed setting helps you reproduce or tweak a chosen density reliably during a shoot.

Suitable for

• Landscape photography requiring long exposures of water, clouds or moving elements
• Portraits shot with wide apertures in bright light to control depth of field
• Creative long-exposure effects and motion blur techniques
• Situations where quick, stepless light reduction is preferable to changing filters

Key specifications

• Filter type: variable neutral density (ND) filter
• Diameter: 77 mm thread mount
• Density range: variable, approximate control from +1 to +5 stops via indexed control
• Coating: Multi Resistant Coating (MRC) for reduced reflections and increased durability
• Mount style: XS-Pro EW (extra-wide) threaded mount designed to minimise vignetting
• Colour: black
• Configuration: single-piece circular screw-in filter

How to use

Screw the B+W 77 mm ND Vario onto the front filter thread of a lens with a matching 77 mm diameter. Rotate the outer element to adjust the density; use the indexed marking to note a chosen setting for repeatable results. Start at a low density and increase until the desired exposure or creative effect is achieved. When combining with other filters, fit the ND Vario as the outermost element to avoid mechanical interference and to maintain the intended density control.

Usage recommendations

Test the filter with your specific lens and camera setup before critical shoots: check for vignetting at the widest focal lengths, confirm colour neutrality and exposure changes across the density range, and, if higher density is required, consider combining fixed ND filters underneath the Vario while keeping the Vario as the outermost filter.
