I made up a short strap, which is custom fitted to my hand by measuring with camera in hand, and then sewn in a locked position so as to not allow the buckle to be entrusted to the safety of the device. The strap came from one of my previous cameras and is made with a half twist and rejoined in a loop to make a mobius strip. The reason for the half twist should be apparent in the images attached. When in place, there is only flat material all the way around the wrist and the camera is totally supported by the strap, to the point that if the hand is opened, it will stay in a ready-to-shoot position. Camera in hand - Camera in mind.......no more forgetting about it ! I've used this strap type for years now and slipping it on comes as second nature.
Obviously, this strap wasn't designed to support the weight of a long lens which normally has its own tri-pod mount, but will always give a sense of security for having your camera tethered to your hand.
Here's a few images to illustrate what I use and how it fits my hand....




These images were shot with my Casio EX-V7 .......primarily used for shooting video, but can do an OK job when called upon. No manipulation was done on these shots, since they were only provided to illustrate the text.
