Just got sony's fx 700 and when set to 24p fx there is significant annoying jitter with panning when I play it back through Sony's Vegas Pro 12 (set at 24P), Is anyone else having this issue. Thanks

if its a fast pan, you're probably talking about strobing. if slowing down the pan fixes it, then that's it.

Also check your shutter speed setting. If your shutter is faster than 1/48 that may be adding to your problem...

Remember the seven second rule.

For any object crossing the width of the frame,it should take 7 seconds or more to be smooth in 24fps recording.

Use 180º shutter (1/48).

If following a car or a bicycle keep them in the same part of the frame as you pan and you will get a nice blurred back ground and a sharp moving object w/o strobing.

Go out and experiment different panning speeds and come up with your own comfort zone. All rules are made to be broken and only suggestions.
