Shooting with Canon EOS 5D Mark II

Overall, filming with the camera is good. There are a few hiccups that make me hesitate from saying ‘Great’.

Firstly, I am finding it quite difficult to maintain consistent camera settings (in particular the ISO) between clips. This does not seem to have a big visual impact on the footage I have taken so far but I would prefer some more control so I’ll be spending some more time figuring out how to lock down the settings as per the discussion in Vincent Laforet’s blog.

Second, the camera crashed 5-times while taking about 25 videos. What do I mean by crashed? The camera flashed on the ‘write-buffer full’ symbol then froze. I waited several minutes for the write buffer to catch up on the clip but no luck. Eventually I gave up and had to pull out the battery to reset the camera. The only clip that I lost was the one where I was on during the crash. I’ve subsequently tested the CF-card on some long clips with no write problems (SanDisk Extreme III – 30mb/s) so I’m assuming the crashes may have been a heat problem. The crashes occurred in a mix of direct sunlight and shade but it was a very warm day (>30°C). The manual and some websites mention thermal issues causing image degradation but I can’t find anything about the camera freezing up so I’ll keep checking there.

Next up I’ll start trying to process the footage.
