K&F concept used to be a second or third tier brand which solely focused on low-cost alternative camera products. It is no longer the case anymore. I have recently bought many of their products including tripod and lens filters. They are all working great and cost about 60% of the name brands.

This True color circular polarizer lens filter is no difference. It has over 28 layers of nanometer coatings which eliminates glare and offers waterproof. As U can see from my sample photos, all the glares were gone after rotating the filter. While I have not used this particular filter long enough to say it is truly scratch resistant, I can say with confidence that, based on my experience with other K&F nano costings filters, nano costing does offer certain level of scratch resistant.

What surprised me the most is the weight of this lens. It is noticeably light weight. In fact, this is the lightest weight lens filter I have ever owned considering this one is 82mm.

Caution: Because this is an ultra-thin filter, it is not easy to remove the filter. I highly encourage anyone who plans to get this filter also get a filter wrench kit.

Overall, I really like this polarizer lens. Highly Recommended.
