Use the belt for a Canon 70D with Sigma 24-105mm F4.0 DG OS HSM as always top. Since thus depend almost 900g lens to the camera, I was a strap of sufficient width importance of offering the opportunity to the camera with lens down over your shoulder. The belt provides both, the material is reminiscent of a car seat and especially the idea of a page to keep smooth and coat the other slip is highly versatile. As a quasi-sling the camera varies as to my right side, handle outwards and lens facing down, making it immediately accessible. The variable fittings that make the belt in no time differently positioned, you do the rest. Not the cheapest option, but better I have not found.
