Video on a 5D

[Scarecrow]

I haven't dabbled with video on my 5D yet, but looking at how video effectively works in a 'live view' mode, I get the impression that any form of autofocus during recording is not possible.

Have I got that right, or is there a fn in the menus somewhere that I need to set that will enable autofocus during video record?

You can hit the AF-on button before you start and it will autofocus, but once you're recording it's manual only.

It is possible to focus a Canon EF lens manually or automatically while capturing a movie with the EOS 5D Mark II camera. For example, when the 5D Mark II is set for Live Mode AF or Face Detection Live Mode AF in Live View, it is possible to autofocus the lens before or during a movie clip by pressing the camera’s AF ON button. However, we recommend focusing before the movie begins for the following reasons:

* The speed of AF in these modes may seem slow to the average viewer if it is performed while recording a movie.
* Live Mode AF with or without Face Detection is a locking type of autofocus; it cannot track a subject moving towards or away from the camera.
* Depending on the lighting conditions, there may be a change in exposure level while AF is being performed.
* If you are using the camera’s internal microphone, it will pick up the sound of the lens’s focusing motor while AF is being performed, resulting in unwanted audible clicking noise.

Therefore, from an aesthetic perspective, you may find it more practical to autofocus the lens before recording begins. Of course, remember that it’s also possible to focus manually at any time.

That answers my question beautifully, thank you.
