New releases always come with minor flaws that are discovered by the few lucky early adopters. It happened with Nikon’s D800 and Canon 5DIII was no exception and had some issues, but they are being addressed by Canon. They have just released a new firmware version 1.1.3 that addresses some problems and adds support to new lenses.
- Supports the single focal length EF40mm f/2.8 STM lens that is to be released at the end of June, 2012.
- Fixes a phenomenon in which an image may become underexposed when using the Auto Lighting Optimizer for continuous Auto Exposure Bracketing (AEB) shooting.
- Fixes a phenomenon in which the backlight of the LCD monitor may not turn off depending on the camera settings and timing.
- Fixes a phenomenon in which the camera’s power may not turn on when a super-telephoto lens *1 is mounted to the camera with an extender*2.
- *1) EF 300mm F2.8L IS II USM / EF 400mm F2.8L IS II USM
- *2) Extender EF 1.4X III / Extender EF 2X III
- Corrects mistakes in the Dutch, Italian, Korean, Norwegian, Polish, and Swedish menu screens.
