These clips are fantastic, highly recommended for hikers/backpackers who like to keep a camera handy. I've used mine with an Olympus OM-D E-M5 MkII on day hikes and a week-long backpacking trip and been very happy with it. I've been able to fit it to every pack I've used, and it feels very secure. Nice not to have to think about whether or not my camera will take a tumble when I'm scrambling around exposed catwalks.
Really a great piece of gear. Get one.
eldudarinoIt's good! Only had it ~9 months and haven't really put it through its paces yet, but so far it + the 12-40mm f/2.8 PRO lens make for a reliable, reasonably versatile (and weather-resistant) combo in the backcountry. I also use a Peak Design wrist leash when I'm hand-carrying, as the grip is not quite as secure on its own as on other cameras. Overall a little heavier than I'd like for backpacking, but still lighter than my full-frame DSLR. I'd previously tried a Panasonic Lumix LX100 for backpacking but wasn't satisfied with the image quality. I'm pretty happy with the Olympus so far.
