This page shows a variety of examples, some single frames and some focus stacked with theSony FE 12-24mm f/4 G.
The sample of the 12-24mm f/4G used here has a consistently weak right side, just like the sample I tested two years ago (on the Sony A7R II)! Quality control at Sony seems to be very loose, as so many Sony lenses are problematic.
2019-11-06: in progress.
Performance at 12mm in the outer 1/4 of the frame is visibly soft with poor depth of field, appearing as if the lens had been designed for APS-C. At 12mm, even an ideal sample of the 12-24mm is likely to require focus stacking for satisfactory results, at least to my standards.
