  • 1Description

The B+W 52mm Circular Polarizer MRC Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention.

Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.
Constructed from high quality Schott glass for optical clarity.
Brass filter ring helps to prevent jamming and provides additional strength.

    52mm Circular Polarizer MRC Filter is rated 4.8 out of 5 by 59.
    Rated 5 out of 5 by from Amazing Filter ! I mostly use this B+W MRC Circular Polarizer in conjunction with my photography, darkening skies, enhance landscapes and saturate colors and to minimize reflections. I love the quality of the filter and construction that's made out of brass ! The filter seems to warm my images a bit but I think that's a normal thing. Make sure not to tighten too much on your lens or it will get a little stuck and if you were to stack filters, I would definitely put this filter on last ! Also remember to use a White Balance Filter BEFORE any filters. Here's a couple sample photos I used with my Fujifilm S5 Pro DSLR and Nikon 24mm f/2.8 AF-D lens ! :)

    Rated 4 out of 5 by from Very robust product - but has a defect B+W is obviously the best brand, when it comes to filters. This one is no exception. But I received one with a defect. When you look towards the lens side; you see that almost gold colored sliver-like line. It rotates with outer glass. You don't see that when you look at from the other side. So it has to be somehow a coating defect (or a scratch?) on the inner-side of the rotating glass. Obviously user can not scratch the coating between two glasses.I didn't expect this coming from a company with such a formidable reputation. Specially when you pay $$ and expect the best product on the market. So that's the reason for minus one star. I'll contact B&H to see what can they do about that. I'll update with the result.

    Rated 5 out of 5 by from Vivid Outdoor Shots I've only tested it out during one session of hiking. Used it on my Nikon D7000 w/35mm DX 1.8 lens. The shots I got had great contrast, sky was bluer, plants greener w/less or no glare. This is a heavy duty quality filter. I've used cheap ones before and this one really lets you know you're putting quality on your lens. It rotates smoothly but because of the rotating ring, it's hard to unscrew the filter. The stationary ring fixed to the lens is much thinner than the part that rotates so you have to squeeze pretty hard to get a decent grip to turn it. It came packaged in a typical plastic filter case with soft stryofoam. B&H shipped it very quickly and it even made it to California the day before scheduled (UPS didn't actually deliver until the due date). I would order this product and similar again and from B&H.

    Rated 5 out of 5 by from Great Filter! This is my first circular polarizing filter, and I have been using it for the last 5 months with no complaints. It is money well spent because it has great construction sporting a brass ring, multi-coated glass, and a plastic carrying case. It weighed in at 1.73oz with case. The filter element is easy to turn and stays where you put it. I use it on my 52mm Nikkor lenses and my Panasonic camcorder with a step-up-ring to really make the blue skies pop.

    Rated 5 out of 5 by from Very satisfied with this purchase. This filter is of very good quality for the price. It mounts to the lens with ease and the movement is smooth. The color of my photos is exceptional across the entire range. The skies are deep blue without muddying and beautifully contrast with the white clouds. B+W filters are a great addition to my camera kit and I look forward to purchasing more B+W filters in the future. So far I have found no cons with this filter.

    Rated 5 out of 5 by from Very satisfied Optical quality seems fine, and polarization effect is as expected. (Note that polarizers work best at 90 degrees to the sun and must be adjusted for each photo.) Threads matched well to the lens, and cross-threading would only be the result of carelessness. Rotating the polarizer was smooth and did not unscrew the filter from the lens. I have only positive reactions.

    Rated 5 out of 5 by from I am pleased with the results.. I needed to shoot through the windshield of a car to take a portrait. The filter did a great job reducing glare and I got the shot I wanted.

    Rated 5 out of 5 by from Essential Solid build, well worth the money. A good polarizer is essential to your kit; I find this one to be really nice.
