I have contacted Canon regarding this, but has anyone experienced any battery level issues with the MIII?
Specifically, when Canon-branded batteries (and this happens with third-party as well) get between 36%-42% of remaining power, the camera turns off as if the battery has no power left. However, if I take these batteries and put them in another camera, they average 1-2 remaining bars. They will not show power in the MIII until after they are re-charged, and even if they are placed on the charger for just a few seconds, they'll then blink with no power on the MIII yet still work fine in another camera (60D, MII).
Has anyone had this problem? I use these for video more than photo, and when recording the video, it's practically impossible to judge when the battery will basically quit, other than changing them everytime they're at half-power.
