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.

Bought to protect the Canon 18-45 RF-S lens. Optically very good. I see no degradation in image quality compared to the lens with no filter attached. Good fit but note that it's slightly wider than the lens barrel so the EW-53 lens hood gets a little tight over the top, but it goes over the filter... easy! Because of this, I have chosen to leave my lens hood in place full-time, rather than taking it off and inverting it for storage.

For beginners, the price is unbelievable and you also get a lens hood that costs more from Canon's original than this whole set would take in its place immediately

I've owned high quality Canon DSLRs for a long time and they're great. But over the years, I've struggled with the combination of lens hood and lens cap. I must have spent hours removing the lens hood, which is almost four inches long on some lenses, to get to the loosening, squeezing things on the outer edge of my old lens caps.

The last lens I bought had one of those center squeeze types and I realized I should have had that type on all my lenses a long time ago.

These caps from K&F Concept are a smart move. They're relatively easy to use even with the lens hood attached, but the depth they offer for your fingertips is just enough. When I put them on, I feel like there is a risk of them falling off my fingertips. This is a bit scary because you don't want them making contact with the glass. You need confidence in this regard, as you cannot see what is happening in the dark area inside the lower areas of the lens hood.

You have an unexpected advantage. Being plain black with no logo or name on them, they remove the word Canon from the front of your camera for all would-be thieves to see. It might make your camera a little more secure.

However, they make up about a third of the price of most lens caps, even by market cap. So they offer good value for money if you are on a budget. I will use these lens caps until I find ones with a slightly wider contact area with my fingertips.

Works as promised.

These lens filters look good on my Canon EOS 200D. Contrary to other reviews, they can also be unscrewed again. The front part of the lens is movable, so you can twist the "half face" into the right position. A clear buy recommendation for the price.

I bought the M42 lens to use with Canon EOS.
I could use it without any problems!
