After talking to Kodak about the SanDisk memory card that wasnt working with my Zx1, I returned it to SanDisk and ordered two Transcend 16GB SDHC cards instead.
Why two? I want 32GB of storage for my Zx1, one way or the other. In 720p at 30 fps it consumes about 1GB per 20 minutes of film, and as we all know... 20 minutes of raw footage results in maybe 5 minutes of usable video material. Since I will be going to a the Amphi Festival in Cologne this summer, I want to be able to shoot some decent video without having to whip out my mini note all the time to offload the raw footage.
With 32GB I can shoot about 10 hours of video before I run out of space (I would still have to swap batteries now and then, of course
). Another cool feature about the Transcend cards is that you get a free USB card reader with them, which is always nice.
