There was a time about a month or so, back when I was still waiting for the camera itself, that this would have frustrated me. Having just gotten the camera though, I took it out for a long spin this past Saturday. One of the things that I was impressed by is that for 4 hours of strait work, the thing took less than 40 % of the battery life. This is constant going / stills and video, with light attachment. I usually travel with 6 batteries, and while I cant wait for the grip, I'm thinking ill be able to survive at least a little longer on what I already have stocked up. Lets just hope it doesn't take took much of the summer, as eventually passivity will give way to frustration...and anxiety.....and eventual madness...
I got 1600 photos from one battery on mine. Was very impressed! However, it's for ergonomic reasons that I like to use a grip - if I'm shooting portrait a lot, I don't like holding my arm in the air.
I don't care about the battery. In fact, it could cut the battery in half and I would be happy. I want it so I can have a shutter in potrait. I shot the PGA's TPC this weekend and I had to do a weird contortion to get shots. The only reason I want it is for that.
