Log profiles make footage worse until you can grade
'Their clips end up looking worse because they use that advanced feature.'
Log is a flat, low-contrast profile that preserves dynamic range for grading - and it is the setting most likely to hurt a beginner, because ungraded log looks worse than a normal profile straight out of camera. He keeps just two profiles loaded on the A7S III, S-Log 3 and Cine 1, and points out that the Canon 1D X Mark II he uses has no log profile at all, so he hand-tunes sharpness, contrast and saturation on a standard picture style instead - which is a perfectly good answer. Both cameras also let you build a custom favourites menu of only the settings you actually touch, and Sony's camera-set memory saves a full snapshot to a dial position for instant recall.
Stops someone buying a camera for a feature that will make their output worse.
I see a lot of people buying cameras because they want to shoot in log picture profiles, but they have no idea how to color correct color grade footage, and their clips end up looking worse.
