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.
