Hello Jit,

The only camera I know that can deliver a NTSC full frame at high shutter
speeds is the PULNIX TM-9700.  It can do this because in contains an
internal field store memory which allows it to store the odd field while
it send the even field.  Then, the odd field follows (reverse order).
The reverse order isn't a problem with EPIX (and possibly other) imaging
boards which permit selection of odd or even fields as the first
field in a frame.

The only disadavantage of the PULNIX Camera is that is noisy when
compared with other cameras we use.  SONY is supposed to coming
out with a similar camera; but, we haven't seen it yet.
