Not sure what you're seeking with the camera, but as far as I can tell, everyone does a lot of post processing to extract everything out of the DNGs.
Speaking from my experience, I tend not to do a lot of white balance adjustments, and spend some time to correct it in post, since is already in the pipeline... I'll try to adjust next time to see if there's any improvement in the results...
Anyway, I'm curious to see your footage, you said you're using primes from macro to 600mm, what aperture can you get on these tele lenses? I've been struggling with my lenses when shooting for wildlife but I've got zoom lenses only...
