Canon EOS 5D Mark III Firmware

Canon 5D Mark III Firmware helps the device to support the new STM lens, fix the LCD backlight backlight does not turn off or the machine does not turn on when attaching Extender and super Tele tube.

Some changes include:

• Better compatible with the new EF40mm f / 2.8 STM lens.
• Corrects underexposed images when using the Auto Lighting Optimizer in continuous exposure mode Auto Exposure Bracketing (AEB).
• Fix the backlight of the LCD screen does not turn off in some tweaks of the machine and leave it for a certain time.
• Resolves an issue where the camera may not start when some super telephoto lenses (EF 300mm F2.8L IS II USM / EF 400mm F2.8L IS II USM) are attached to the extender kit (Extender EF 1.4X III / Extender EF 2X III).
• Correct language errors with Dutch, Italian, Korean, Norwegian, Polish and Swedish.
