I also think it’s hard to do from an engineering perspective. There’s already no room left, and the lens mechanism itself is rather error prone.
It would be great if Ricoh could improve on the dreaded lens error first. Maybe the front unit with the sensor needs a redesign. This would be also a great opportunity to add a clickable button.
But what a great idea! I hope we’ll see a clickable ring in the future, even if it won’t be on the GR IV (yet, haha).
Oh yeah, that AF. It’s not as much of an issue on the GR III as it’s easy to operate it so that basically everything outside your arms’ reach is in focus, but on the GR IIIx it can get annoying pretty fast.
That said, the latest firmware updates slightly improved the AF. During my absolutely non-scientific tests the AF went from completely unusable in low-light situations to somehow workable when you try really hard.
And before somebody comments that the AF is perfectly usable, I want a MILC class AF in the GR, nothing less.
More customizations, or at least more consistency would be very welcome. I still can’t get used to the functions of the lever & wheel switching depending on the mode you’re in. This is also something that could be fixed in firmware.
They definitely should source another component for the wheel. It happened (too) many times that I came back to my Mac just to realize that most of my photos were overexposed and went straight to the trash.
