So I'm really not a fan of neck straps in general, but all the hand straps I find seem to only be useful if you're using the shutter button on top of the camera. 99% (well probably more like 96%) of my shots are portrait orientation, so of course I have the vertical grip, but I can't find a hand strap designed to be used with the portrait shutter release on the grip. Has anyone come across such a hand strap?
