I use the R-Strap RS-4 is currently a Sony Alpha 57 and a Tamron Zoom travel. In the last Asian holiday he has really served me well - especially when the photo stops by bus or climbing in the area. I'm usually too cautious and had considered, nor to deploy additional security, but this is really unnecessary, because the screw on the camera body (tripod thread) keeps really well. Occasional check whether everything is secure, absolutely enough (which incidentally is like in real life). It is also helpful along with belt and fixed camera, the best behind closed doors with the right background music (eg play-me-the Song-from-death) to face, in front of the bedroom mirror and pull the "Colt" on the harness and pull the trigger. Sounds ridiculous? Is it also, but it saves you staging and testing under observation. Buy recommendation? Absolutely.
