I am a new EM-5 owner having come from a Nikon D7000. I like the EM-5 very much and find that I carry it around a lot more due to its convenient size and low weight. I also find it very convenient to carry the camera around using a neck strap. When doing so the back of the camera hangs against my chest and in that position I was worried that the EVF would stay on and drain the battery. So to minimize this possibility, I set the EVF Auto Switch to Off, set the display to the EVF, and the sleep timer to 1 min. Now after 1 min the EVF turns off when the camera goes to sleep, and won't turn on again until I half press the shutter button and wake up the camera. Although this works fine, is it the best strategy to minimize battery drain short of turing off the camera? If not, I would be interested in hearing what others may be doing to address this. Also, does the EVF use less power than the screen?
