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...

Not every camera product works on every camera.That is why I'm not like others rating this at zero or one.Just returning it.Ghost double images, and blurry photos. Remove the filter,and images return to pure sharp. Put on a 100mm-400mm f5.6 Lii.With 6dii in bright sunlight. Who knows?Hitting the return button now.

The optics on this filter are extremely clear and sharp and the polarizing works very well. It's nice and slim. I highly doubt you'll find a better quality filter at this price. It's a really excellent value. It comes in a hard plastic shell which is great for storage.The performance of this filter is pretty close to filters that cost five times the price. The only downside is that it has an aluminum thread instead of the brass threads you find on more expensive filters, but I haven't yet had any issues with the thread sticking; it's been very smooth, so I would say this filter is well worth the money.

Currently I am using a K&F Concept 77mm Circular Polarizer Glass Filter Ultra-Slim/Multi-Coated for my Canon 24-105mm L Lens.I really llike this K&F Concept Circular Polarizer over my other previous filter because it really does deepen the intensity of blue skies and reduces and eliminates glare.My previous version is also normal, while this has a tint via its multi-coating which reduces reflection, glare and improves saturation.The K&F Concept Circular Polarizer is also made of Japan optical glass and if anything, this provides another added protection for your expensive lens (especially when you don't have your lens hood on).Overall, I'm quite pleased! Highly recommended!

TIP: This filter is made to be able to rotate w/o unscrewing...make sure you realize there is a second/thinner ring that does the tightening to your lens. I didn't realize this at first and thought the filter was stuck on the lens.I compared this filter to a competitors UV and no filter. Both at F4.0, 50mm, 1/1000 on my Sigma 17-50 f2.8 lens on my Canon. I could clearly see that the colors have more depth and richness to them. It is a lot more evident in the orange and greens of the plants in my photos. It does darken the image a bit but in well lit environments this will be on my lens from now on!Filter arrived in a plastic hardcase, sealed in a plastic bag. Filter ring has a nice grip knurl for adjustment.
