Canon 2191B001 overview

  • 1Description

Useful for minimizing reflections and glare and enhancing the overall color and tonal saturation is the 77mm Circular Polarizing Filter from Canon. By filtering out light that has become polarized due to reflection from a non-metallic surface, this filter helps to produce a noticeable increase in saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto-exposure functions.

Reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Arrange and filter directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Lessens haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Optical glass is used in order to maintain clear image quality with high contrast and color fidelity.

    Canon 2191B001 reviews

    77mm Circular Polarizing Filter is rated 4.8 out of 5 by 21.
    Rated 4 out of 5 by from Excellent:Engineered by Canon, for Canon Bear with me here. This filter is excellent. . . here's why. . . 1. Taming the leaf-reflection burnouts: This Canon polarizer is a great investment. I does a fantastic job of cutting down on the glare and refraction which occurs in tree leaves which are being inundated with direct sunlight. With no polarizer, leaf refractions often appear as exposure burnouts which can be distracting to the viewer and make your work look a bit amateurish. The Canon polarizer does wonders for taming these burnouts and replacing them with evenly exposed, rich, saturated color (but not too saturated!). 2. Beautiful blue sky: Though mostly imperceptible to the naked eye, water vapor in the atmosphere does in fact refract sunlight. The sky is therefore kind of like a giant see-through scrim/reflector, which is why it often appears more of a baby blue rather than a royal blue. The Canon polarizer reduces this refraction and turns your skies into a nice rich blue. While you can always turn a sky more blue in post production, it's definitely a good idea to get the best possible image you can in-camera. 3. Quality is everything: If you shoot with Canon L-Glass, why would you put a $60 filter on the end of a $2000 lens? Your image is only as good as your weakest piece of glass. Yes, this filter is pricy, but it was engineered by Canon for Canon. 4. Lens cap Your Canon lens cap will always fit perfectly on the end of your Canon filter. With other brands of filter, your lens cap will fall off. 5. Lens versatility I own the 24-70mm F2.8L, the 70-200mm F2.8L, the 17-35mm F4 L and the 24-105mm F4 L. This filter fits all of these lenses (77mm diameter) and more! Wow, I talk way too much. Enjoy your Canon filter. It is excellent.

    Rated 5 out of 5 by from Worth The Price Cheap (under $100) polarizing filters take the edge off the image quality of the Canon L lenses I use. These Canon polarizers do not impact the quality.

    Rated 5 out of 5 by from Excellent choice A must have for shooting outside or around water. Superb canon quality. Zero lens flare.

    Rated 5 out of 5 by from Worth the price! I bought a cheaper one first and was disappointed I should have followed the advice I had seen online and gotten the Canon filter. why put a cheaper filter in front of expensive glass I use the Canon 100 - 400 zoom and this filter though expensive does the job perfectly. You can adjust it through the lens hood opening no problem and it really does the job, so lesson learned.

    Rated 4 out of 5 by from High Quality Polarizing Filter If you need a 77mm circular polarizing filter, this is it. However, it is putting more glass in front of your lens, so it will somewhat, reduce the quality and more iportantly, reduce the amount of light to your camera. If you have a good quality lens in back of your filter and a tripod, not much of a problem.

    Rated 3 out of 5 by from Should have stuck with what I knew Just did not seem to compare to the B+W polarizer I already have. Did not get the same deep blue skies. Threaded on/off easy and Canon lens cap fits perfectly, though.

    Rated 5 out of 5 by from Thin Polarizer with great results I am using this on my Canon 5D Mark II with 70-200 f2.8 lens. I'm getting great results at the lake. The polarizer is thin and threads easily.
