i read it at this blog: http://www.philipbloom.co.uk/Philip_Bloom/Kit.html
under KIT it says the F350 has Full progressive 1080P implying the ex1 doesnt? Read further below when it gets to ex1 it doenst mention it.
Yes, the EX1 is full progressive. The F350 isn't; it scans from interlaced chips and drops to half resolution when you speed up the frame rate past 30fps. The EX1 doesn't, it uses a progressive chipset and scans progressive at all times.
To be considered full high definition 1080 progressive wouldn't the camera have to have the capability to shoot in this format at 60 frames per second ? If the camera does not have this capability then it has no higher resolution than its 720p shooting mode.
