Just curious why it takes so long to get the camera out of the holster. With my OP Tech harness and Tamarac case, I can get my G9 out, turn it on, and shoot, all with one hand, in less than 5 seconds. I also use a Lowepro holster for my DSLR with a regular neck strap for things other than hiking, and can do the same with it. I keep it unbuckled when I am using the camera often unless I am doing something more strenuous where I want the camera to be more secure. It becomes almost like a quick draw and your hand goes straight for the grip, switch, and shutter release. The reason I like to have the case or holster is to keep dust and sweat off the camera as much as possible.
