Yesterday driftwood released what is probably the last and greatest update for hacked GH2 cameras.
Settings Here for Apocalypse Now (original reference unavailable)
This group of settings is called Apocalypse Now and works to achieve a better and smoother color matrix that not only improves upon the native 4:2:0 h.264 of the camera, but also softens the natural sharpness of the Panasonic lenses when used in video mode.
If you have a higher-end monitor capable you should be able to see the subtle changes in color rendition to the blue channel in this still.
Quickly testing outside with the “soft” version settings, the difference on foliage is immediately noticeable in regards to sharpening. (14-140 @18mm LA7200)
These are just preliminary tests, but I would hazard to say that I would now recommend using Panasonic electronic lenses without fear of sharpening artifacts.
