In my opinion that's perfectly normal motion blur. Any object in motion is going to have blur in front of and behind it. The solid-color area in the middle is just the overlap, it'll have ghosted images before it and after it.

Try panning against something that's got high contrast, like a white fence against a dark background, and you'll see "ghosting" both in front and behind.

I don't know that it's a technical term :-) But the previous that is described is really just a hard description of the "picket fence test."

But looking at your still? It's normal motion blur, as Barry mentions.

ok.
maybe it's not visible in still. maybe i have differetn aproach to this still because i saw it in motion. i give up. when i see it on big hd monitor it looks strange.

will shoot both with panasonic dvx 100 progressive mode and Z1 sf. will see what will happend.

thanks for your thoughts.

Untill now all the footage (stills) I have seen from the FX1 seem very dark !!!! like it is heavily underexposed. Is this due to the inexperience of the operator or is the FX1/Z1 just not very good in low light conditions. Maybe someone can upload some footage to prove to me that the fx1/z1 is capable in producing well exposed material with good colour saturation !!!!!! I was planning to buy the z1 but now I am leaning back to the PD170
