> Ive found this online. Has anyone used this?
I've used it, along with practically every other solution that is out there! It's a well made, robust piece of kit and I rate it highly. The only thing against it is that it doesn't adjust wide enough to be attached to most rucksack straps. Also check out the Spider Pro holster system - same idea.
The Think Tank set up works well as the bags are pretty small & attach easily to the bespoke belts or to pack belts etc.
Also check out Black Rapid's straps. I use one. It allows the camera to be captured around the back of the body so it doesn't swing around when climbing. You can then release things, bring the camera to the front and shoot. The camera slides up and down the strap, rather than being attached to one point.
Carrying an SLR when climbing is always going to be an inconvenience. Either deal with it, or keep it in the top of your pack and shoot at belays.
