Long before the release of the GH5, I remarked how adjusting even relatively straightforward settings like white balance, curves and contrast on cameras like the G80/85 was confusing for some people (myself included), and that it would result in yet more perplexity for photographers not accustomed to setting things like knee, gamma, hue, etc. on the GH5. But never could I have imagined that custom AF settings would create such a stir.
We've already seen this video, several times in different threads, OK? Hanriverprod is entitled to his opinion.
