This filter fits my Canon RF 800 f11 perfectly, even the lens hood fits on it, and vice versa. This is in contrast to the other reviews where people write that it is too thick. The optical quality is also excellent; I don't notice any loss of light or discoloration. A clear purchase recommendation from me.

Nothing fancy about UV filters, you just don't want them interfering with your shots, K&F's does a great job with their glass filters. When you're investing hundreds of dollars on a lens, you want something that will protect it without distorting it, and K&F filters do that.

I have no complaints about these filters. I run them on all my walkabout lenses that are carried around. Flare resistance is very good thanks to the coatings, and it's rare that I have to make an adjustment to a shot due to flare. The only exception was when I was taking photos in a museum, pointing up at objects near bright lights. But other than that, they clean well and let me walk without a lens cap for those candid shots.

Good price-performance ratio. Cleanly processed and fitted perfectly on the thread of the optics

I originally only received the case which is supposed to contain the lens filter but no filter so I contacted the company and after providing some information they sent me a replacement which arrived quickly. Great company and good value for what you get.

I was a bit skeptical after the reviews that said that the filter was 0.5 mm too large and that a lens hood on the outside of the lens no longer fit. This is NOT the case at least with the Nikkor lenses 20 mm and 24 - 120mm Z with 77mm filter thread. Everything fits perfectly. I also couldn't make out the supposedly protruding groove on the 77mm UV filter. Visually everything is as usual with K&F 1a.

had previously used a common UV filter. It's not bad. Only under certain conditions would glare or aberration occur. For the most part it worked fine. But it still annoyed me. So I ordered this K&F UV filter. WOW! What a difference! The glass is so clear you can't tell it's in the case! And that's how clear my photos became with it! Definitely worth the price difference! All my filters are now K&F brand. The quality is excellent!
