Dunno really... I just don't like the image. It's seems like it's an older generation of sensor than the GH2. DR seems lower, as well as poorer color rendition (despite all the options). Just because a camera has 100+ gamma and color matrix dials doesn't mean that the sensor is going to be any better at rendering color. The motion of the image doesn't look right to me either. This has been discussed before though, some people see the difference between Inter-frame recording and Intra, some don't. Could also just be the way the AF-100 processes the frames... who knows. All I know is that the GH2, with an all-I or low-GOP, patch produces similar motion to dedicated digital-cinema camera like Red or Alexa. AF-100 doesn't.

That's all I can really think off. It's up to you though... it's your cash. ;)

AF200?
