My non-scientific response here, Internal looks the best. Yeah, I have found even with the Sony's and GH5 that Log images held more noise. F-Log I thought I wanted and now all I want is a decent rec 709 image, I still find the X-T2 crushes those blacks just tad much. I really like the mid range push with Astia and at this point I'm gonna stick with this, this week. I have a three day shoot with serval clients.
