This is the same video from the F550
And here the video from the SX230
The SX230 is a great camcorder replacement, whereas the F550 is a mixed bag. The F550's video quality is better then any Fujifilm camera's I had before. And I would consider it's pure video quality higher than the SX210's, but it's autofocus is less reliable after zooming. Anyway, the SX230 is the clear winner here.
