Interesting video ..... LINK
I have responded to the link to DPreview forum, but for convenience I'll post my response here:
I bought a GR III last week and find the autofocus is far far better than that illustrated in the movie clip in this topic here. I have tired it in bright light and low light, and it's fine, better than my original GR was, and I thought that it was ok.
Perhaps what might explain the difference is that I am using the latest firmware and I doubt the original post was. It can be downloaded from the Ricoh website . I bought my GR III with V 1.11 installed and first thing I did was install V 1.20.
It would be interesting to hear from those who found the focus slow with original firmware installed and have subsequently upgraded to the current version. Did you notice an improvement?
Here's a list of firmware updates with some details:
Changes to V1.20
Add the following enhanced features
[Grain Effect]
[Grain Effect] has been added to [Monotone], [Soft Monotone], [Hard Monotone] and [Hi-Contrast B&W] mode as adjustment items under [Image control] of the 6 [Image Process Setting] menu in the [Still Image Setting].
[Horizon Correction]
[Horizon Correction] has been added to the 7 [Shooting Assist] menu in the [Still Image Setting].
