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.

nothing fancy about UV filters, you just don't want them to effect your shots, K&F's does a great job with their glass filters. When you invest 100s of dollars for a lens you want something to protect it without distorting and K&F filter do that.

I always get filters w/ non-slip design when it's available. It makes a huge difference. I compared it w/ Hoya HD2. I shot these w/ Canon M50 w/ Nikon 35-70mm f/2.8 AF ZOOM-NIKKOR.
1) No filter. 2) K&F. 3) Hoya HD2.
Sure, it's not a great test but I can't tell any difference between all 3 of them. The Hoya was optically as good as K&F except it was very staticky that I had to return it. I didn't like it's not non-slip either. The K&F is not staticky at all and very easy to clean. When there's no reflection, it looks like there's no glass inside the ring. Kind of like magic. It's very well made.
I use it on my Zeiss 50mm f/1.5 Sonnar T* ZM. There's no play and it fits perfectly. Very happy about the purchase.
