I've got a Isco Ultra Star projection lens on a Gh2 with the moon hack. My taking lens is a Nikkor 50mm and there is a lot more artifacts in the footage than with just my spherical lenses. Macroblocking on walls, horrible banding on walls and while it looks better when I film outside in daylight the clouds are full of blocky noise. Im using adobe premiere pro cs6, does anyone have any tips on how to fix these type of artifacts?
