I�d say the Canon�s exposure automation is better - a lot - than the sunny 16 rule - and it is not always sunny - inside a building for example. Better way to good exposures is to observe what the meter sees and use exposure lock, it can read and use half stops very well. BTW I used ordinary alkaline cells with no ill effects and I read from somewhere that the meter compensates for different voltages. All the best!
