B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter
The B+W 77mm Kaesemann Circular Polarizer Extra Wide 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.
Kaesemann-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses.
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. The extra wide filters feature an oversized ring that is much larger than the male threads for attachment to the lens. This oversized ring permits the use of glass that is also larger and helps to prevent vignetting when using wide angle lenses. Lens hoods should not be used in conjunction with extra wide filters as vignetting may occur.
- Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
- Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
- 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.
- Kaesemann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils.
- Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.
- Extra wide filter ring provides room for a larger glass substrate and reduces vignetting when used with wide angle lenses.
- Constructed from high quality Schott glass for optical clarity.
- Brass filter ring helps to prevent jamming and provides additional strength.

Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
Am new to photography and a friend suggested I get a circular polarizing filter to help capture the colors of Fall. I contacted B&H and told them what I needed and the lenses I had, and they suggested this filter. I have already noticed a huge difference in the color quality of my photo's and the way it cuts glare on the water. I love this! Am very pleased with it!

Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
I'm amazed by the quality of these filters--I'm amazed that anyone buys any other filters---I am amazed (cynic that I am) that I am as happy as I am with this product.....Thank heavens for the craftsmen and women who manufacture this product---It has made my photography, better, different, and much more personally satisfying

Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
I use this for landscape photography primarily on the 17-35mm lens. It genuinely avoids all vignetting on the 17mm end. Colour is completely neutral which is great.
I would suggest 2 minor improvements:-
1) It might be good to tell potential customer what the outside diameter of the extra wide mount is so one can easily get a lens cover for it.
2) the case that come with the filter is poor. For such an expensive filter (or for any filter for that matter), I expected a better case. This plastic case is misaligned and doesn't stay closed. It springs open on its own in the bag.

Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
If you shoot 24mm to 200mm with Nikon lenses, the 77mm Kaeseman Circular Polarizing Multi-Resistant Coating (MRC) Glass Filter (Extra Wide) by B+W is the one for you.
There is no vignetting, the color rendition is excellent.
It is a bit wider than the lens, so using your standard lens shade will be out, but it is worth it for the quality of the image.

Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
The price tag may open your eyes, but using this filter will also - it is indispensable when it comes to snow, high-glare conditions or on water, all of which i have encountered - the color saturation is unparalleled (especially on blue skies), and the glass is superb - an investment to be made for a lifetime
Pros
- No vignetting
Cons
- Does not include a cover
Best Uses
- Cuts glare in bright sun
Comments about B+W 77mm Kaesemann Circular Polarizer Extra Wide MRC Filter:
I needed a circular polarizer for my 16-35 lens that did not vignette at 16mm. I looked everywhere for a review but found nothing, so went ahead and ordered from B&H with confidence. The item was exactly as described. What I really like about this polarizer is that it has 95mm threads on the front so you can always add an extra filter to the front. Easily screws onto lens with a good fit. It turns smooth when mounted to lens and does not have too loose a feel.
