Hey Gregorio, unfortunately as Jonas said, the G7 doesn't have the capability to do internal recording and external monitoring at the same time.
You can, however, use a tablet or phone as a monitor through WiFi. This is good for remote monitoring and / or control. But as expected, this method will have lag and wouldn't be good if your intent is for focus pulling.
What are your focusing methods? Do you use peaking or a combination of peaking / magnify? I'd suggest using the magnify feature to pinpoint your focus.
I don't shoot in C-Log often and usually just stick with WideDR. Maybe that's causing an issue. Perhaps someone can comment on if C-Log needs more sharpening in post?
I don't believe the 24mbps is going to cause you an issue in terms of sharpness. That would affect more of how robust the image is in post.
If I would have to guess, I would second that it's probably a characteristic of the lens or a focusing issue.
This is amazing, thanks for the article. Can't even begin to imagine what he had to go through to get his work out there (culturally, financially, you name it). Truly inspiring!
And to think some people criticize his films for "lack of production value" according to the video. Yes he had ~$10,000 to work with, which was more back then. But if you adjust for inflation, comes out to about $234,000. Miniscule budget even with all of the widespread technology we're spoiled with today.
I can't comment on the A6300, but I recently shot with the 80D. I'm usually a Panasonic shooter (GH3 and G7). I also shoot frequently with Canon 5D III's and a C100.
In comparison to all those cameras, and for the price point of the 80D, I was somewhat appalled by the build quality and feel of the camera. The AF tracking was pretty decent, but I wasn't really digging the ergonomics and controls. At this time, and at this price point, I'd find it hard personally to pull the trigger on an 80D if my focus was video.
Magic Lantern RAW could always bump the quality and features, but I don't know their support for the 80D or if you want to pursue that workflow.
I'd second your recommendation here. I currently have a GH3 and G7. I'd make one small correction though - the GH3 does *not* have focus peaking. Such a shame, since the G6 came out right after with peaking. All the other pros you listed hold true though. Love my GH3.
Kudos to you for suggesting the T3i for a beginner. People get snobbish and want to disregard it, now especially. I cut my teeth on the T3i.
