I recently bought a Peak Design Clutch, because I wanted to try out a hand strap. I often go without a longer strap, and was using a wrist strap as a safety strap. My question relates to hand straps generally, but I wanted to give some background in case that matters . . .
When I tighten the strap across the back of my hand, I find that I can't comfortably operate the thumb or shutter/dial controls. I need to loosen the strap in order to easily access the controls on the back of the camera with my thumb, or the shutter/dial on the front.
Now, the point of a hand strap, I presumed, was so that you could hold the camera without needing to grip it with your fingers - helping with both safety and fatigue. Loosening the strap enough to be able to comfortably use the camera means that I can't let go of the camera safely (or, more accurately, with full confidence).
Am I missing something? Is there some way to position the strap to avoid this issue, or is it a fundamental ergonomic problem? I should note that I have a 6D, and my hands are bigger than average (but by no means comparable with dinner plates).
