When I am shooting photos with my DSLR I never use the longer exposure the camera is capable of unless I have a tripod with me because I can’t hold still long enough to take a shot that isn't blurry unless the exposure is short and quick. I can only imagine shooting video using your camera would be even more difficult. If you are after more stability for your video and photo shooting, the Pocket Rig is aimed at you.
This little device comes from a company called Edelkrone and the Pocket Rig connects to the bottom of your camera using the tripod attachment. It's specifically intended to help stabilize the camera when you are shooting video with your DSLR. The Pocket Rig is no larger than a battery grip and is made from machined aluminum and stainless steel. The weight of the device is 1.25 pounds.
The Pocket Rig has a pair of industry standard 15mm RODS that fold inside. In two seconds they can be deployed and ready to use with follow focus, matte box, and handles for ease of use. Check out the gallery to see some of the ways the Pocket Rig can be used. Pricing and availability are unknown.
