Mounted on a 55-210mm from the Sony a6400 kit. In general, these are filters that are not easy to use for beginners like me. You have to understand where the light comes from and look in the viewfinder for modifications. For this one, the adjustment ring is small. For the price, it is an acceptable compromise, I can do it with big fingers. Important, it is not easily compatible with the lens hood. I installed it without the lens hood and then it was impossible to put it in place. There is surely a possibility by putting the lens hood in place and then the filter at the cost of fingerprints on the filter. I have not tried it. It is a good filter to discover polarization and its usefulness on a mid-range body and lens.

Arrived next day. Fits perfectly on my Canon camera no issue like some have said with screwing it on and off. The dial maybe a little stiff to turn but don't find it too be an issue. No issue putting it on nor taking it off my camera. Can't wait to test its effects and learn to get the best out of it before we go away...

-I’m surprised and impressed by the quality and nice feature of this filter-The lens uses Japanese optical glasses plus the blue coating allow maximum light transmittance, reduce reflection and glare, which improves quality image comparable to other major brand CPL filter. The frame is built with quality aluminum that helps smooth adjustment and thread on/off. The CNC Trapezoidal Pattern also help secure the filter to the camera lens. It’s also stackable so you can screw it on another filter, say another K&F Concept ND filter-I use the Kodak Color Control Patches for my testing as below-No Vignetting at corners thanks to the ultra slim rim design-No image distortion by comparing filtered image on a test pattern-Finally I posted some images with filter and another without for comparison
