72mm circular polarizing filter with rotating mount and nano coating

B + W Filter Company

B + W 72mm Master High Transmission Circular Polarizer MRC Nano camera filter

SKU CH-JTRV-AT5MZ

72 mm circular polariser with rotating mount cuts reflections from water and glass while boosting colour saturation for landscape shots at 90° to the sun.

  • Enhances colour saturation for richer landscape images
  • Rotating mount lets you adjust polarisation effect visually
  • Cuts reflections from water and glass for clearer shots
  • Works with modern cameras for TTL metering and autofocus
  • Maximum polarisation achieved at 90-degree angle to the sun

Purpose and audience

The B+W 72mm Master High Transmission Circular Polarizer MRC Nano Filter is built for photographers who want richer colour saturation and fewer reflections. It works with both analogue and digital cameras that use TTL metering or autofocus systems. Landscape shooters gain deeper blue skies and more vivid foliage. Product photographers can see through glass or water surfaces without post-processing.

Mount and workflow integration

The 72mm thread screws onto matching lens fronts and the rotating mount lets you dial the polarisation effect while composing through the viewfinder or monitor. Circular polarisation keeps modern metering and autofocus functioning normally. The filter adds a multiplying factor of 2 to 3, equal to about 1 to 1.5 f-stops, so exposure compensation is needed. It does not suit lenses with smaller or larger thread sizes.

Light loss and handling

The high-transmission coating reduces flare and keeps the light loss to the stated 1 to 1.5 stops in normal use. Maximum polarisation occurs when shooting at a 90-degree angle to the sun. The slim frame avoids vignetting on most wide-angle lenses. No power, batteries or firmware are involved, so reliability is purely mechanical.

Questions about this item

How many f-stops of light does the 1.5 multiplying factor cost me in practice?

The filter's multiplying factor of 2 to 3 is equivalent to 1 to 1.5 f-stops of light loss, so you will need to open the aperture or slow the shutter by that amount.

Does the rotating mount or the glass itself get warm enough to affect handling during all-day landscape shoots?

The filter is passive optical glass with a rotating mount; it generates no heat and draws no power, so temperature and noise stay at ambient levels.

My lens has a 72mm thread — is that the only requirement for this polarizer to work with my camera?

Yes, the 72mm thread matches your lens, and the circular design works with nearly all modern cameras for TTL metering and autofocus.
