Firmware 1.1.0 for EOS 5D, 1DIIN


Doug Kerr

Canon has announced field-installable firmware 1.1.0 for the EOS 5D and EOS 1D Mark II N.

On the EOS 5D, one of the three problems this is said to solve is:

"3. Correction of the phenomenon 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."

I think we have seen this curiousity reported here.

The other two anomalies said to be corrected are:

"1. Enhancement of direct printing with specific printers. [There are more details of this on the download page.]

2. Correction of the communication errors that occurred when shooting with EOS 5D and EOS Capture software after shooting about 138 shots."

The firmware download page for the EOS 5D is here:


On the EOS 1D Mark II N, the new firmware is said to only to provide the improvement in direct printing.

Not what the rumors had, it was suppose to fix bugs with a 4mb SD cards I thought.
Who prints directly from the N anyway???

Instead of a direct print button which is a just a marketing ploy to sell more Canon printers, I would much rather see their engineering efforts dedicated to built-in wireless. I know the current wireless speed is a problem but a wireless connection need not be dedicated to live storage of images. It can be programmed to download when the camera is not shooting thereby freeing up storage space.
