use this filter for Sony 70-200 lens on my Sony a7r4. The magnetic ring base makes attaching the polarizing lens easy. I use this polarizing filter to take compressed landscape shots on sunny days. The glass quality is good. The images look good.

K&F makes great quality filters and this circular polarizer is no exception. Plus the fact that it's magnetic so you can attach and detach it quickly makes it a great choice. Being compatible with other manufacturer's magnetic filter systems is also important and this 82mm K&F Concept polarizer fits its my Kase Revolution magnetic adapter ring without any problem.

Two things make this filter stand out. 1) The polarizing impact brings out colors, removes unwanted reflections and generally improves the photos I take 2) Magnetic. These things "clip" into place. Once I tried magnetic , I really never wanted to go back to thescrew-on type. High quality glass and optics. Yes they are a bit more expensive than the screw-on type, but well worth it for the convenience and speed of use.

This magnetic polarizing filter kit is the perfect upgrade over the traditional style of filters. The base allows you to use other magnetic filters from K&F as well. It is extremely simple to switch or remove filters with this setup, and will greatly improve your workflow. The polarizing filter is a great filter option for cutting out glare from water in landscape photography. It also adds more contrast to skies and various high exposure scenarios. I have also used this filter to cut down the glare from glass and metallic items. This makes it an amazing accessory when photographing cars and cityscape/architecture.

About 75% of the filters that I have used have been K&F. And as all of the other filters, this one does not disappoint. I love the magnetic base. I purchased other magnetic filters simply because I love the way the filter held. The filter is clear and does not affect my pictures negatively. I will surely recommend this product.

K&F somehow made the best magnetic filter ring on the market. It holds very well and the fit is perfect. I have rarely used a cpl until this one it has stayed glued on my 35mm lens. The materials are excellent quality and the filter itself presents no color cast. I really hope k&f make more filters magnetic.

The filter does a great job of polarizing so I can see through glass on set, and doesn't have any color casting to it. it's easy to adjust still, and the magnetic mount threads on easily. The magnets are decently strong, so I never felt worried about the filter falling off, as well

knew that there was no industry standard in these magnetic filter specifications, and so magnetic filters (and also magnetic thread adapter rings and magnetic lens caps) from different manufacturers don't always "stick" when mixed together. So I was concerned whether this K&F magnetic CPL filter and K&F magnetic thread adapter ring are compatible with the Urth-brand magnetic filters and a magnetic thread adapter that I already was using. I am happy to report that, at least in this 77mm filter size that I tested, the K&F and Urth magnetic filters seem totally compatible / interchangeable: - I was able to attach Urth magnetic filters to this K&F magnetic thread adapter - I was able to attach this K&F CPL filter to an Urth magnetic thread adapter. - I was able to stack the K&F and Urth filters magnetically Aside from the magnetic properties, this K&F CPL filter seem to work as expected. It has nice and even anti-reflection coatings, and didn't seem to impart any offensive/unexpected color cast as it removed glare from shiny leaves and darkened blue sky. I have no complaints. So I would like to give this K&F magnetic CPL filter + magnetic thread adapter 5 stars.

First things first, its maximum polarizing effect is not as great as my b&w polarizer. But that's not really important. Why? Because I rarely go for maximum polarized effect; I adjust my filter to what looks "right." More importantly, it's much easier to use than my other polarizer. The magnetic mount lets me pop it in with complete ease in microseconds. Plus, because of all the twisting I'd do with my previous polarizer, it sometimes would get stuck so tight, it was a pain to take off (when you try to twist it off, your grip would slip because you'd be twisting the turning part of the filter). Not a deal killer by any means, a little elbow grease would get it off, but again you lose precious seconds which often leads me to not putting it on my camera it at all, a lot of times. With this, that's a non-issue. I should add that, even though I mentioned that the max polarizing effect isn't quite as strong as my other filter, it's still quite strong, and the optical quality is terrific as well. Highly recommended.

This is a beautiful filter that’s part of their easy magnetic attachment system and it comes with a magnetic adapter which can be used for most brands of magnetic filters. fit and finisher excellence and the optical quality is additionally excellent. The polarizing ring turns very smoothly and easily without slipping on the magnet. This is a very precision machine piece. It’s excellent at eliminating glare which can be very difficult to remove with post processing software.
