Neutral Density Camera Filter B&W XS-PRO VARIO ND MRC-NANO 72 mm

B&W XS-PRO VARIO ND MRC-NANO 72 mm is a variable neutral density camera filter that provides adjustable light reduction between approximately +1 and +5 stops. Designed for photographers and videographers who need flexible control over exposure, this 72 mm filter fits lenses with a 72 mm front thread and features an extra-wide (EW) XS-Pro mount intended to minimise vignetting on wide-angle lenses. The glass carries a multi-resistant coating with nano treatment for improved surface protection and reduced reflections, and the filter is supplied as a single black unit to be used alone or combined with other fixed-value ND filters for greater attenuation.

Advantages

The variable ND mechanism allows continuous adjustment of exposure without changing shutter speed or aperture, enabling longer exposures, controlled motion blur and the use of wider apertures in bright conditions. The XS-PRO VARIO mount includes an index setting for repeatable density positions and an extra-wide frame to reduce the risk of vignetting on many wide-angle lenses. Multi-resistant coating with nano treatment increases scratch and dirt resistance while reducing surface reflections to preserve image contrast and colour fidelity.

Suitable for

• Landscape long exposures and smoothing moving water
• Portraits with shallow depth of field in bright light
• Motion blur and creative effects in street and architectural photography
• Video work requiring consistent exposure control without changing camera settings

Key specifications

• Density range: approx. +1 to +5 stops (continuously adjustable)
• Mount: XS-PRO VARIO EW (extra-wide) to reduce vignetting
• Coating: Multi-Resistant Coating (MRC) with nano treatment for improved protection and reduced reflections
• Colour / finish: Black frame
• Compatibility: Designed for use as outermost filter when stacked with additional filters

How to use

Attach the B&W XS-PRO VARIO ND MRC-NANO 72 mm to a lens with a matching 72 mm filter thread. Rotate the front ring to adjust the ND density to the required light reduction, using the index setting to note preferred positions. For longer exposures or stronger attenuation, combine the variable filter with additional fixed ND filters mounted behind the VARIO filter; ensure the VARIO filter remains the outermost element. When shooting wide-angle lenses, check for vignetting by testing different density settings and, if possible, perform a short series of trial exposures to confirm the desired effect with your specific equipment.

Usage recommendations

Perform test shots at multiple density settings to identify any colour cast or cross-polarisation effects and adjust white balance in-camera or during post-processing. Keep the filter clean and store it in a protective case when not in use; gently clean the coated surface with a microfibre cloth and an appropriate lens-cleaning solution to preserve the nano coating. When stacking filters, avoid over-tightening to prevent binding and re-check focus and composition after changing density.
