Panasonic recently introduced 10 new cameras.
They appear to be using the engine from their top of the line FZ50.
They are so new, that only the FZ8 has been reviewed;
but they all have video at wide-screen 848x480 in addition to the normal 640x480 and 320x 240...........all at 30 frames per second.
You should get good video results with any of the 10 cameras:
Model numbers: FZ8, TZ2, TZ3, FX30, FX10, FX12, LZ66, LZ7, LS60 & LS75.
I hesitate to recommend the small Nikon cameras because for the past two years they have been using a slow engine with shutter lag times around one second. They do have acceptable video performance.
They have introduced about 5 new models but none have been reviewed.
So I don't know if they fixed the slow shutter lag problem.
Olympus has been a mixed bag with about 50% of their cameras turning in a maximum video frame rate of only 15 frames per second.
Part of the problem is the slow xD memory card they use.
They too just introduced a batch of new cameras that still show a mixed bag of frame rates. There have been no reviews of their new cameras.
