You can adjust pretty much every setting on this camera.
I have it adjusted to turn the screen off after 1 minute of no interaction with it (while shooting too). There is also a small button on the bottom left corner, next to the screen, to turn off the screen.
I've also disabled the LEDs, which I assume must allow the batteries to last a few more minutes. No WiFi/Record flashing lights for me!
I have 3 batteries right now. I bought the dual charger (comes with a battery) + an extra battery.
I wish I could share the coupon. It was a one time use coupon
