If you're looking for an alternative way to carry your DSLR around, take a look at the Capture Camera Clip System
– a new device in the making that lets you clip your DSLR to belts on trousers and backpack straps. Your camera's accessed easily thanks to the built-in quick release system and the redundant twist lock will stop the camera falling off if you press the quick release button unintentionally.
The device is made from die cast aluminium parts and there are plans to release an attachment that lets you fix your camera to non-flexible objects such as bike handlebars and roof racks.
Peter Dering, the Camera Clip System creator said on the kickstarter website: "Capture can adapt to just about any activity. I've taken my camera downhill skiing with Capture, and it works great (though you should connect your backpack's chest strap across the lens barrel if you want to do this). It's really up to you to decide what activities you want to use it for...Capture will hold your camera...that I can assure you."
The Camera Clip System will retail at around $70.00 when it's released in July. If you'd like to pre-order a unit and support Peter's project, you can through its Kickstarter campaign
