Polarizing filters are designed to reduce glare and reflections of light while at the same time greatly enhancing the natural colors and saturation of an image. This filter is produced by Hoya which is one of the most respected producers of photographic filters, ocular lenses, and optical components in Japan. Marumi offers a slightly confusing four distinct ranges of circular polarizers, each with different glass/coating combinations. The DHG Super range gets a water and oil-repellent coating, which works well, easily beading away droplets and resisting fingerprints, albeit not quite as well as the Lee Polariser.

Without getting too technical, a polariser only lets light of a certain polarisation, or phase through the glass. When light bounces off objects, or is scattered in the atmosphere, it affects the phase of the light waves, and so by only letting light through that is of a certain phase, it can cut down on reflections and alter colours in an image. The CPL filter effectively eliminates the reflection of the non-metallic surface, thereby improving the image quality of the subject, and increasing the clarity of the picture can effectively increase the saturation of the color. The lens adopts a double-sided polishing process and is used on a telephoto lens.

"Moldproof", "Waterproof", "Anti-scratch" and "Anti-greasy". While having the characteristics of hard scratching, it will not have any impact on the image quality, even if it is contaminated with water droplets or oil, it can be easily removed; Ultra-thin Brass Frame】The frame is made of brass material with an ultra-thin design. CNC integrated molding has both hardness and flexibility, smooth and durable installation, 0.01mm-level processing accuracy, the frame is highly fitted and fixed to the lens, and there is no vignetting when installed on wide-angle and telephoto lensesDSLR Cameras Canon EOS DSLR Cameras Nikon DSLR Cameras Digital Compact Cameras Instant and Single Use Cameras Instant Cameras Instant Camera Film Single Use Cameras Instant Printers Memory Cards & Storage SD Cards Micro SD cards CFexpress cards Compact Flash and CFast cards Card Readers SSD and USB Drives Scanners Cameras Mirrorless Cameras DSLR Cameras Digital Compact Cameras Video Cameras Lenses Mirrorless Camera Lenses DSLR Lenses Lens Filters Lens Accessories

The quality of the glass used in the filter is very high, with no noticeable color casting and image degradation. After extensive testing on a multitude of lenses, I can confirm that this filter does not noticeably affect the image quality.

Reduces flare and ghosting that can occur when filters are attached to the lens, with little or no impact on the original performance of the lens

When you use it to cut down on reflections, the effect on something like water is pretty profound. In this example, I used it on the water of a canal I was walking by and it completely cut the reflections out. The K&F polariser performed as expected for a polariser. It’s one of those things that’s hard to review, as it pretty much does what it says. I didn’t notice any undue colour shifts, outside of what you would get with a polariser. It did reduce the amount of light getting through, but that is also normal for a polariser. The only minor issue that I had was getting it to stay on the lens, but that is something that I’ve had with every filter I’ve ever used on this lens, so its not a fault of the filter. In fact, I actually dropped it because of this, but that only went to demonstrate how tough they are, because it wasn’t even scratched. Conclusion Double Coated】Adopted 18-Layer multi-resistant double coating technology, the green coating helps effectively reduce filter surface reflection and the ghosting while making the filter anti-scratch, water repellent, oil and dust resistant.
