K&F makes some of the finest UV Filters for the price. The ring also includes grooves so you can take off the filter easily. I would definitely recommend it to people who have expensive lenses and want a peace of mind.

I’ve always used B+W filters but decided to give this one a try because of the price and was pleasantly surprised by the quality of this filter. The optical quality and fit and finish of the filter is on par with the more expensive filters from Germany.

This filter just helps keep the gunk off the front element. This protection helps keep the lens from slowly getting micro scratches and ruining the whole lens. Easier to replace a filter then a lens.

I bought it for my Canon EF 24–105mm f/4L IS II USM to protect the lens, it threads on and off rather easily and I haven't even noticed it being on. If it does degrade the image, it's not enough to be readily noticed.
