Technical question: Battery charge and AF behaviour...

Post by Stany Buyle »

I have a technical question:
Is it possible that the functioning of an electronic device (read camera AF system) is influenced by battery charge running lower to low?

Thanks in advance.
Kindest regards,
Stany

Hi, Stany!

The camera's internal systems are supplied power by tightly-regulated circuitry which compensates for dropping battery voltage. If the battery becomes low enough that there is a potential for the internal power to be affected, it will shut down rather than allow any of its functions to be compromised.

I have specifically tested for lens AF slew-rate effects from battery voltage, both fresh versus near-discharged battery states, and also comparison between the 11.1V and 7.4V battery packs for a camera which can use either by virtue of its battery grip, and found no changes in slew rate dependent on battery voltage.

So, if everything is working correctly, you will not see AF performance affected by low battery voltage.
