I just purchased my first digital camera an A540 Canon Powershot.
My question is what tips could you give me to conserve the battery power?
Will turning the camera on/off frequently cause excessive power drain?
What are the optimal settings for auto power off and lens retraction?
Is it best to buy rechargeable batteries instead of using disposable ones?
Thanks in advance for any and all responses
