This page shows the true optical distortion of the Nikon NIKKOR Z 24-70mm f/2.8 S at 24mm and 28mm, and shows the sharpness losses when distortion correction is used. The 45 megapixel sensor of the Nikon Z7 captures as litte as 40 megapixels of detail in the outer zones with the NikonZ 24-70/2.8, along with degraded micro contrast, due to distortion correction.
Distortion correction guarantees a loss of sharpness, because some of the pixels in the frame must be stretched apart. See Overview of Distortion for Nikon NIKKOR Z 24-70mm f/2.8 S for an overview of the negative impacts on image quality from distortion correction.
