Looking at the comparisons and differences between the two camera's in terms of resolving power, color and dynamic range. Included both smooth and nostalgic picture profiles as compared to Technicolor's Cinestyle.
GH2 -Nippon Kogaku 50mm 1.4 @f/4
Valkyrie Cinema Smooth hack - Avg bitrate 105Mbps Max 151Mbps
5dmrkii - Nikkor 80-200mm ais 4 @f/4
Magic Lantern Bitrate setting at 3x - Avg bitrate 38Mbps
Both Cameras Focused On The Lamp
The ghosting you see in the Gh2 image is not a fault of the camera it is just an older lens that does not have the same antireflective coatings of the newer aid series.
