I have the 50D. Question: does the camera use more battery power to process the raw files when shooting raw compared to processing the jpeg? I am thankful I started shooting entirely raw but noticed that ever since I changed to shooting raw my battery dies in about 2 hours of shooting (bp-511a battery) and I have to change. My charger came with the camera which is about 2 years old and I never take the battery out of the charger until the charge light is fully lit and not flashing and the camera shows it fully charged.
Just trying to narrow down the problem of batteries going dead. When I first got the camera I shot raw sparingly and mostly shot jpeg. Could the raw processing and writing to the CF card (takes longer than jpeg) be the culprit?
Thanks for all responses.
