K&F Concept 82mm Thread & Magnetic 2-in-1 Lens Filter Cap Only Compatible with K&F Magnetic Swap System

Very easy to use. The magnetic is strong enough to not falling off easily. It hasn't come off in my camera bag or outside yet. If any thing it's a little too strong for the thinness so it's a little difficult to open quickly.

This is the second cap I bought first one was to small,I went by the dimensions of the filter second one I bought it. Don’t get me wrong. Their products are excellent and high-quality it just frustrating. Spending all this money on a lens filter to have it not work The way it should. Double check your lens and filter measurements so you don’t waste money

This cap simply would not work. The magnetic strength was simply to low to say on. Can not recommend this cap.

These magnetic lens caps work well to protect the lens glass. They adhere tightly and I’ve never had one fall off. They are very thin, so they don’t add much length to your lens when attached. The only downside is that they are impossible to remove when a lens hood is attached to your lens, no matter what the configuration. It’s impossible to get your fingers around the cap without removing the lens hood first. It would be nice if these caps had a gripped protrusion on the front for removing when a lens hood is present.
