Canon EOS 5D + EOS-1D II N firmware 1.1.0
Canon has today released new firmware for the EOS 5D and EOS-1D Mark II N digital SLRs. The EOS 5D firmware addresses three issues; Correction of communication errors between the 5D and EOS Capture after a certain number of shots, Use of E-TTL flash metering mode using the ST-E2 Speedlite Transmitter in conjunction with the 580EX Speedlite and finally the 'enhancement' of direct printing to two Canon PIXMA Pro printers. The EOS-1D Mark II N firmware update includes only the direct printing improvement with no other bug fixes.
