Has anyone else noticed drastically increased battery life with their D300 compared to a D200? I shot some youth basketball last night and with only 18% battery life used, as indicated by the menu display, I took 323 shots. Conditions - Continuous servo, 9 point dynamic mode AF. ISO 3200, 1/250 at f/3.2 manual exposure. 70-200 VR lens. Compressed 12-bit RAW. I did a lot of sequences, so I was chimping minimally with the D300 compared to how I usually shoot other things with the D200, but the 323 shots still extrapolate to almost 1800 shots on one battery.
