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.

I used this filter on my Canon Rebel T7 with EF-S 18-55mm IS II lens and a size larger adapter. It works beautifully, crystal clear, screws on with ease. It comes in its own hard case with a cleaning cloth.

These were a huge help for my photos. Great quality and lightweight. I use with my canon rebel t7 and have no problems.

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.

I added this to my Canon Rebel T3i camera. The camera is a few years old and I love it. Cleaning the lens is always a chore, you need to get out the right cloth and be careful not to scratch it! But I can just use my shirt with it. If I scratch it it was $20 and I can get a replacement. I'm really happy with it!

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