Hello everybody, my LP-E6 battery shows 100% on the charger but when I put it into the camera and check the percentage from "battery info" it says that it is at 75% (approximately). Is my battery fake or is there another problem, does anybody know?
Hello everybody, I recently bought a used 5d mark 3 and for some reason whenever I change the shooting mode on the dial it makes a loud clicking noise, my friend has the same camera and his doesn't make any noise. The noise is noticeably loud.
