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 Kadarius Gentry

It's no secret they work; I don't know why cameras these days don't come with them. But since they're so cheap and come in threes, it doesn't matter. I hope Revain will add more of these things to his "Extra" items soon. These particular holders are very sticky and I like that the tape feels more like butyl rubber when you peel it off. Unlike most double-sided tapes, this one is soft and almost viscous. Once you have attached this suction cup, it can no longer be loosened without great effort. The elastic straps can be rolled up and moved or stretched and pinned to the side, and the elastic straps that wrap around the lens are well made and the laces are flat so they don't interfere with the fit. I've never used them on my own rigs (I usually keep the cap in my left pocket) but I bought these for my stepmom who uses a Tamron lens and these caps are so springy they snap at the slightest bit jump off shock. Now that I have it, I will never be without it again. All in all, a hassle-free purchase.
