Review on Foto&Tech Camera Lens Cap Keeper Holder with Elastic String Anti-Loss, Compatible with Canon Nikon Sony Panasonic Fujifilm Pentax Sigma DSLR SLR Evil Mirrorless Cameras Video Cameras - Pack of 3 by Kory Shelton

I love these! I used it on my Nikon 3300. It's small, but small stickers stick! I took it on a trip where we did a lot of hiking and off-road jeep driving. These little bugs have survived. The rubber hasn't come loose either. Haven't lost a lens cap. The lens cap has not come off. They saved me because sometimes I thought I had lost the lens cap and remembered it got caught on those holders. It's so convenient - just remove the lens cap, don't worry about putting caps anywhere to keep it from getting dirty, and just start shooting. It was good to just shoot and enjoy the moment and not worry about putting the lens cap on and then losing it. And when the picture is taken, the lens cap hangs down so you can put it on and protect your lenses. It wasn't bothersome that it's attached to your camera. I was just making sure my lens cap didn't get lost. I took my camera everywhere and it came in handy. I've only used them for one ride - so I don't know how long they will last but it's been 5 months and these little things are still on my lens caps and camera. Goodbye.
