I really like the idea of wireless camera control for some better camera control that has been mentioned here. Taking hunting pictures on solo trips of myself can be challenging without being able to to see the view finder to help make subtle changes. This gives me camera control remotely up to 150 ft away on my iPhone and iPad or for those with similar Android devises. It will come in handy for not only backcountry photography but I'm hoping it will help get some out of the box shots when I'm out hunting, landscapes, wildlife, night photography, movie, macro, HDR, etc.... with my camera. This got a editors pick in Outdoor Photographer. I'll be using CamRanger on my Canon DLSR. Right now it's only for select Nikon and Canon DLSR cameras but it's some real cool remote technology. I'll attach a couple quick clips on what is does but there is more at the site for those that might want that control for their camera too.
I know most DLSR cameras are not lightweight cameras but I'm takeing it more on backcountry trips these days because I'm able to do a bit better job with my photrgraphy.
