Just to let you know that Firmware Version 1.0.6.1.00 is available to download from the following URL if you are in the UK :

EOS C300 (http://www.canon.co.uk/Support/Consumer_Products/products/camcorders/Digital/Digital_Cinema_Camera/EOS_C300.aspx?type=download&page=1)

Full instructions are included with the download and it's a pretty straightforward operation.

Firmware Version 1.0.6.1.00 incorporates the following features:

1. Genlock synchronization can now be used to synchronize the camera’s 24.00P, 24.00PsF, 23.98P, and 23.98PsF input signals.

2. Adds the Korean language to the camera’s menu.

3. Minor corrections to simplified Chinese language menus.

NB: Firmware version 1.0.5.1.00 incorporates item 1 and 2 above.

I must have missed 1.0.5.1.00.

It's definitely a step forward and I'd like to say how excited I am but . . . . .
