Is it merely for carrying around the camera without having it hang from your neck or shoulder? Does it also stabilize the camera when shooting? Can it help with hand fatigue - perhaps you don't need to hold it as tightly?
I've been shooting a lot with the 7D and the 100-400 and getting used to the fairly substantial feel of this combo. Coming from a T3i and much smaller lenses, the weight and bulk is taking some getting used to. It's probably more to do with not being used to the weight and the ergonomics (I am pretty strong and athletic, so it is not purely a strength issue) but I feel more fatigue with this combo. Will a hand strap help with this?
Finally, any recommendations for hand straps that will work with a 7D? The E2 Canon strap is 45 bucks - like every other accessory from Canon, it sounds like excessive. Looks like the herringbone leather hand strap is highly regarded - price is close to the Canon one. Any others to consider? I plan to get an RRS camera standard plate for it and connect the strap to the lug on the plate. I assume that will work.
