I photographed this Snowy Owl in the severe cold during the very last moments of the sun recently. As a long time sufferer of Raynaud's syndrome, keeping my hands warm is of paramount importance during my Snowy Owl workshops. I typically use big & warm mitts with several hand warmers to keep my fingers warm. Although I have mastered how to control my camera with the mitts on, it takes a lot of practice and I do miss the occasional shot.
The Sony RMT-P1BT Wireless Remote Commander came in useful while set-up on this Snowy Owl, waiting for it to open its eyes and look at the camera. With the Remote Commander tucked into my mitt, I was able to trigger the camera via Bluetooth without taking my hands out of the warm mitts.
While it is true that a wired controller would have worked just as well to trigger the camera, it is connected to the camera with a wire that is prone to get tangled in my extensive cold-weather gear, and since it is wired, I would have to leave it attached to the camera in the cold anytime I moved away; this means putting the frozen device back into my warm mitts and defeating my efforts to keep my fingers warm.
