We were having battery issues with the borrowed camera for this weekend, and had to stop and recharge them more often than normal. The report on our camera (which is in the shop) is that after 229,469!!! pictures in the last 12 months, it is time to replace every moving part inside. We will have our camera back in time for the next STT trackday. I hopethaqt you all understand. We were still able to get over 5200 pictures this weekend.
