Canon EOS 5D firmware update

Version 1.1.0 is now available.

You can download it from Canon here.

This fixes the following:

1. Enhancement of direct printing with specific printers.
2. Correction of the communication errors that occurred when shooting with EOS 5D and EOS Capture software after shooting about 138 shots.
3. Correction of the phenomenon (their word; what they mean is ‘error’) in which the flash mode settings are changed from E-TTL to M (Manual) when EOS 5D is used in combination with Speedlite Transmitter ST-E2 and Speedlite 580EX.

Of these #2 is probably of most interest. I wrote about Canon’s Capture software here. I haven’t actually taken 139 shots in a row using Capture – indeed, that’s unlikely to happen any time soon – but it always pays to keep current on these things.

I have installed the upgrade on my 5D and it seems fine.
