There have been many conversations here and elsewhere regarding battery life. I thought I would share my recent experience.
I have just spent an interesting, if tiring day pounding the halls at Photokina. I had with me my CL, 11-23 & 18-55 lenses & three batteries. The camera was set to record raw+jpg (small). I used the viewfinder only with minimal chimping & diving into the menu. The first battery lasted all day at Photokina, and even into the following day walking around Cologne. Once the photos were in Lightroom a quick count revealed 462 exposures before the battery symbol started flashing red.
To my mind, very impressive.
