No Dylan published his review, which you can see below. Here are the main points:
it’s not the cheapest adapter
allows you to autofocus with the more modern Nikon G and E type lenses
good build quality
mounting on GFX mount does not sound quite as smooth as mounting a GFX lens on the body or a Laowa lens. On the other side, the Nikon mount part feels good
ability to control aperture
you have an aperture ring on the adapter for G type lenses, and you can set it to AUTO for E type lenses
E type lenses with magnetic aperture can be controlled electronically via the GFX body
G type lenses are not really fully supported. Aperture control is purely mechanical and the adapter doesn’t actually know which position it is in. Aperture value is not send to the camera. The lens can only communicate to the body what its widest aperture is, but if you stop down, it is unable to tell you who much it stopped down
loose aperture ring
aperture stops are very close together, hence not easy to be accurate
autofocus speed depends a lot on the lens.
you will see wobbeling of the contast AF detect system
GFX100 phase detection system is not supported
You won’t get Nikon level focus speed, because the GFX system is not capable of that
if you accept an autofocus speed a bit slower than native GFX lenses, then it can work for you
there is more or less strong vignetting depending on the lens
wide open, sharpness is not quite as high as on Nikon cameras, as the Nikon lenses where not designed to resolve over such a large sensor. If you stop down, things get much better
for more sharpness better use GFX lenses
This is the summary of the video below. But Dylan posted an article about it also on fstoppers, that you can read here.
Many FujiRumors readers are getting their long awaited Fujifilm X-T4 in these days. As a consequence, I also already get the first firmware suggestions and possible bug reports.

Loving the X-T4 but why the regression in the Q menu so custom simulation names aren’t shown?
the Q menu custom items can’t be renamed as it is possible on X-T3
So, even if you set the custom names, they will not appear in the display when pressing the Q button (as they do on X-T3 & Co).
Just thought i would share my findings about the IBIS in the X-T4. Fingers crossed they release a firmware update for this.

I just got my pre-ordered X-T4 several days ago. After setting it up similarly to what I had on my previous X-T3, I came up a couple of ideas for even greater customization:
Drive dial in video
Currently, the DRIVE dial only controls camera behavior in STILL mode. Why not propagate it into MOVIE mode, as well? I suggest that each DRIVE setting activate a dedicated video profile. Just a few (potentially predefined, but modifiable) example profiles:
HDR mode
Activates the F-Log video recording.
CL mode
Activates 120 fps slo-mo recording.
CH mode
Activates 240 fps slo-mo recording.
Dedicated Fn-button customization for STILL and MOVIE modes.
This could further improve the (already almost perfect) camera usability. As an example, the Fn1 button can be customized for triggering different actions, depending on currently selected recording mode:
STILL mode
Turns depth-of-field preview on and off.
MOVIE mode
Turns zebras on and off.
I’ve read several times that Fujifilm executives may follow your blog and listen to customer feedback. Maybe, there is a (albeit small) chance that these thoughts can materialize?
