They also have coatings that repel water, dirt, dust, and oil from your fingerprints. Some have anti-static coatings. The top-of-the-range filters have coatings that harden the glass. These make the filters nearly unbreakable.

Ultra-high light transmittance】 The lens uses K&F Concept's exclusive coating technology, and the reflectivity as low as 0.15% can eliminate 99.2% of polarized light and ensure 45% light transmittance. 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 A polarizing filter improves the vibrancy of water and lets you see below the surface. Your sky becomes more vibrant and reduces atmospheric haze. Some vibrancy tools in photo editing programs may be able to simulate contrast and color. But you can’t edit out reflections and glare. Germany HD Optical Glass】16 layers double-side coating with almost zero light distortion. Also effectively reduce filter surface reflection and ghosting while making the filter anti-scratch, water repellent, oil and dust resistant.

The polariser filter can be rotated once attached to the filter thread to achieve the desired polarisation effect. More importantly, the new HD polarizing filters use magic polarizing material that loses less light. Most polarizers lose two stops of light. I measured this one, and it loses only 1 and 1/6 stop (one and one-sixth of a stop) of light. This means sharper photos at lower ISOs than using regular polarizers, about one full stop better. The second attribute of a 82mm Polarising filter is to saturate colour, which is especially handy when shooting landscape photography that is being drowned out with harsh lighting. This system means the polarizer is large at 105mm in diameter, allowing it to cover numerous different lens diameters. It’s also very easy to rotate, and it clips into the holder much more easily than trying to screw a conventional polarizer onto your lens. However, the clip-in mechanism is surprisingly difficult to detach again, requiring more squeeze than is comfortable. Another consideration is the combined filter, holder and adapter ring cost, which is significant.

I use filters for filming outside which sometimes can be challenging because of the light, the sun comes up from the clouds, manual settings, everyting over exposed which is very bad for video. When buying a polarizing filter, it is important to know the diameter of your lens. This is measured in millimeters and is usually stamped somewhere on the lens itself. Since the HD glass is so tough, it can be made thinner and therefore weigh less. The 77mm Hoya HD polarizer weighs 32.7g, while the superb Nikon 77mm Polarizer weighs 35.4g. The Nikon does have a slightly thinner 4.88mm mount, but hey, this lighter filter is what Glenn was banging on the counter. Try that with a Nikon.

A few companies use a magnetic attachment to replace the screw-on design. You first screw on a magnetic holder to the front of your lens. Then the magnetized filter pops onto the holder.

Since the ND isn't variable, there's no dark X. And no vignetting at 16mm, unlike when I use my square filter set. Ultra Slim and Lightweight】Super slim and lightweight aluminum frame, maximum reduce impact on light and effectively avoid dark corner for wide-angle shooting. Ultra Slim Filter Frame and Lightweight】Slim aluminum frame, maximum reduce impact on light and effectively avoid vignetting for wide-angle shooting. Before/after: Polarizers cut through reflections on water and glass, and improve contrast and colours of skies (Image credit: Future) These are so easy to use and the quality is fantastic - both the build quality and the picture quality. I can't see any colour cast whatsoever from both the CPL & ND filter. I think you would really need to pixel peep to see any sharpness difference, and even then I'm not sure there is.No “X” cross on images】Say goodbye to the "X" cross on images, K&F utilize cutting edge technology you're going to say goodbye to this common issue with wide angle lenses and variable ND filters.

A polarizer filter is a piece of specially coated glass that fits onto the front of your lens. It is designed to filter certain waves of light. You may not be familiar with polarizing filters in photography. But you might have encountered polarized sunglasses. Because polarizers are mainly used by landscape photographers, build quality is a factor. The best polarizing filters are lightweight and protected by a strong, metal casing. The quality of the metal casing determines how easy the filter is to screw onto your lens and the ease of rotation.They come in a padded cover with an inverted zipper to prevent some water from getting inside in case of rain. It can be clipped on your belt or anywhere else for convenient wearing or carrying.
