Michael Andrew (06.07.11, 2:52 AM): The lens was fixed at 100mm, it didn't change at any point during the testing, so the loss of resolution couldn't have come from that. The only variables that changed were distance and the setting of Movie Digital Zoom, so the rules are different. In fact, when shooting from a further distance, the DOF should increase, and the original size images (first set are at 1:1) ratio, there is loss of resolution in the background. While there are some varibles such as wind, ground vibration, etc, I just don't see how "Full HD Resolution" quality is maintained by this feature, even in pristine lab environments. As far as chromatic abberation goes, the control isnt really showing it even as the 3x Movie Digital Zoom, it is more likely a compression artifact.
Rob (06.07.11, 12:44 AM): You said you used a 70-200mm lens. Could the varying focal lengths also effect the sharpness of the image, giving it the appearance of a lower quality? Chromatic abberation (sp?) looks like it played a small part as well when looking at the black/white card. I would also suggest looking at these in the 100% view. That is where every pixel is drawn on the monitor at its 1:1 ratio.
