Hoya HOYAB67CRPLW 67mm Warm Polarizer Filter

The Hoya Moose 67mm Warm Circular Polarizer was developed in collaboration with renowned wildlife photographer Moose Peterson, and its design reflects a very specific photographic philosophy. By combining a circular polarizing element with an 81A warming filter, this single piece of glass accomplishes what would otherwise require stacking two filters—reducing reflections and glare while simultaneously adding a pleasing warm tone to the scene. For wildlife and scenic photography, this means deeper blue skies, richer greens in foliage, minimized glare on water surfaces, and a natural warmth that reduces the cold blue cast often present in open shade or overcast conditions.

As a circular polarizer, the filter is fully compatible with autofocus and TTL metering systems, and its effect is adjustable by rotating the front element. The 81A warming component is always active, which makes this filter a specialized tool rather than an everyday polarizer. Photographers who shoot primarily in natural settings will appreciate the convenience and optical advantage of not stacking filters, which can introduce vignetting and additional flare surfaces. The 67mm thread size fits a range of popular mid-range and telephoto lenses commonly used in wildlife photography.
