Could you please test out what I`ve reported here[1]? It`s for X-T3, but as the same bug was present there, I guess the "fix" is the same, too.

In short - in AF-C mode, with "SHUTTER AF" set to ON (for AF-C) and "SHUTTER AE" set to OFF (for AF-C), on holding shutter half-pressed and pointing camera from light to dark scene (or vice versa), exposure change is delayed and rather slow (smooth), requiring you to wait a few seconds until the exposure gets to what it should be before you can take the shot.

Yes Boogisha, my X-T3 (FW 4.12) behaves exactly as yours. There is a long delay in AF-C while the exposure slowly adjusts if I use your settings. There is no such delay with Shutter AF set to OFF.

Thanks for confirming! So there`s some rather weird "SHUTTER AF" and "SHUTTER AE" entanglement still, for AF-C mode, former unexpectedly affecting the latter.

I`m now curious if X-T4 is better here, or just the same, possibly making a difference whether we`ll see this one fixed (and on X-T3), too... or not.
