Overview

The Hoya 46mm Circular Polarizing Filter is a screw-in optical filter that selectively blocks polarized light to reduce unwanted reflections and glare in your photographs. When shooting scenes with water, wet surfaces, glass, or lush foliage, the filter cuts through surface reflections to reveal the underlying color and detail. It simultaneously deepens blue skies and increases the contrast between sky and clouds, producing more vivid, punchy images straight out of the camera without relying on post-processing adjustments.

The filter mounts to any lens with a 46mm front thread and features a rotating front ring that lets you precisely control the intensity of the polarizing effect in real time as you compose your shot. Coatings applied to both glass surfaces work to suppress internal reflections and ghosting, helping to preserve image sharpness and contrast. Designed for full compatibility with modern autofocus systems, this circular polarizer will not interfere with your camera's AF or metering accuracy. It is a practical, well-priced tool for outdoor and landscape photographers looking to improve image quality at the point of capture.

Frequently Asked Questions

Both are Hoya 46mm circular polarizers, but they carry different ASIN/model identifiers, which may reflect different production runs, packaging, or regional distribution. The optical specifications and function are the same.
While it will physically protect your front element, a circular polarizer reduces light transmission by about 1-2 stops and can affect exposure in low-light situations. It is best used intentionally when you want its glare-reducing and color-enhancing effects, rather than as a permanent lens protector.
Circular polarizers are effective on reflections from non-metallic surfaces such as water, glass, and foliage. They have little to no effect on reflections from bare metal surfaces.
On very wide-angle lenses (roughly 24mm equivalent or wider), the filter's ring thickness can introduce vignetting in the corners of the frame. At standard and telephoto focal lengths, vignetting is not an issue.
Use a microfiber cloth or lens cleaning tissue with a small amount of lens cleaning solution. Avoid pressing hard or using abrasive materials, as this can wear down the anti-reflection coatings over time.
