I went out shooting tonight with 2 fresh charged batteries loaded in my battery grip. I was using ND Grad filters and was using live view to position the filters. I had live view on a lot. I was shocked when all of a sudden I was totally out of batteries. I only took 40 or so shots but had live view displayed for a lot of the time. From the time I made it to the beach to the time the batteries were dead was no more than 1 hour or so. I am thinking that having the live view on that much ate the batteries up. What do you think? Also both batteries are brand new. 1 was fully charged and the other 95%. Thanks!
Also, I have the LCD brightness all the way up, and not sure if it matters or not but I was taking raw+jpg.
