I have just returned from my annual trip to Norway to shoot the Northern Lights. This year I used a Sony PMW-350 with a NanoFlash and they performed superbly, which was just well as this year we were clouded out for all but 2 nights and even then there was a thin layer of cloud making the Aurora dim and diffuse. One of these days I'm going to get the funds together to go and spend a month up in Norway during the winter and really make a go of shooting the Aurora. It is such a beautiful subject and video cameras are now sensitive enough to capture many of the finer details that are lost with long exposure still photographs.
The clips were shot using the Slow Shutter at either 32 of 63 frames recording 1 frame every second timelapse on both the 350 and NanoFlash. I did have to add in some gain this year due to the faint nature of the Aurora, up to 6db at times and as a result the pictures are grainier than I would have liked. Even so I have to say that the 350 is super sensitive. There was another person with me (Phil Clemo) shooting on one of my EX3's and the footage from the 350 is quite a bit better than the EX3 material shot at the same time.
