Corner looks quite a bit better to me.What's improved？
Corner:
Center:
Images showing unprocessed RAW files with no sharpening applied in Lightroom.
The number of stars on the photo indicates the GR version: three stars represent the GR III, and four stars represent the GR IV.
Edit: ignore that, I mistakenly followed the order I saw in the thread title (GR III first).
Based on this single test, the GR III files seem slightly sharper in the centre and significantly sharper in the corner. What's your test methodology? How many frames did you make with each etc.?
If this isn't an LR profiling, copy variance or testing methodology issue and is genuinely what we should expect from the lens, then it's obviously very disappointing.

How is the af speed of the updated lense?

Makes me dizzy, hope not this is true.
not what we see in the DPR studio comparison.

I hope we’re seeing some testing artifact and not a real sharpness comparison because this isn’t looking good. Any chance the focus is slightly off for the IV? It almost seems darker and possibly OOF

It's not at all what we are seeing in the dpr studio test scene, so I'd take this comparison as a non-representative test.
The dpr test shows the gr4 to have sharper centre and sharper corners.

TBH if mine looks like that I might return it. It's supposed to be better than the GRIII in terms of sharpness (center and corner). Hoping it's not the camera. Is the RAW SOOC or was there any import related processing/correction done via Lightroom or something? I don't mean this as an insult to your test or workflow it just seems like you should be getting "better" shots with the GRIV.
Raw, unprocessed, sharpness zeroed. I will provide the more samples and raw files later.
Thanks for doing that. It’s a public service to your fellow Ricoh users whose GRIV is on back order
I added a few high-contrast objects to the scene, and it appears that the IV is only performing better in terms of chromatic aberration, not so much on the sharpness.
GR IV on the left
Left is GR IV; right is GR III.

I think it’s difficult, as you said, to differentiate between CA and a possible sharpness difference in this real world side by side. Also, the apparent exposure seems a little different between them, with the GRIV looking a little less shadowy. To my eye the GRIV looks better in this newer shot in terms of CA, sharpness, and perhaps DR. Thanks for posting!
The exposure difference could be due to changes in sunlight, as I didn’t take the photos at the exact same time. I captured them as close together as possible since I only have one tripod.
For your test… Was image stabilization disabled on both cameras while mounted on the tripod?
Not sure of the answer to shutter speed. I do know that image stabilization will introduce vibrations/movement when mounted on a tripod. The sample images in your GRIV examples do appear softer, and that could be caused by more vibration from the robust IS system of the GRIV.
Should you decide to repeat this test… Also be sure to trigger the camera remotely (if possible) or by delay countdown timer.

Sorry, I just returned it — the camera’s IBIS occasionally starts vibrating when it’s facing downward, and I didn’t want to deal with potential repairs.
My main point isn’t to compare which camera is better, but to note that the GR4’s lens improvement is only marginal relative to the price jump.
And by the way, I didn’t just take one shot — I took a burst of shots and selected the sharpest one from each camera. So I don’t think IBIS would have much of an effect.
