I used the Capture Pro for the first time yesterday on a long walk. How easy it is to have my camera close by! On a strap around my neck, it dangles back and forth that rubs and then bangs against my side or hip... With this my camera hangs tight and silent against my chest!
There is a very small amount of space in the system, which is normal according to Peak Design, but that could irritate you if you are sensitive to beeps / creaks ...
It's a metal clip and brace, with a tiny bit of space in between, which moves when you walk. You can hear that metal on metal softly.
I have a Canon M3 with an 18-150 lens attached to it, and maybe a heavier combination is less bothered by it? And I think I also try to lubricate everything with candle wax, then it may already be gone, but otherwise it is also fine to act!
