This photograph was created with the Canon 600mm f/4 L IS II USM lens and the Canon EOS 5D mark III handheld.
YES! The new firmware update arrived for the Canon 5D Mark III. The main improvement is now the possibility of autofocusing at f/8 instead of f/5.6 only. This means that a lens with a maximum aperture of f/4 can now be combined with the 2X teleconverter and keep the autofocus with the central censor. This feature was previously only available for 1D bodys. Thank you Canon!
Go ahead and download the new 5D Mark III firmware update to benefit from this significant upgrade. Once the .FIR file is downloaded on your computer, save it on your compact flash by using a card reader. Put the card in your camera, go to the wrench symbol menu (4th yellow), then Firmware Ver.
