Distortion and Distortion Correction from 20mm to 35mm
This page looks at distortion and distortion correction across the focal length range of the Fujifilm GF 20-35mm f/4 R WR, at 8 different focal lengths. It gives outstanding insight into what to expect over the zoom range.
When a lens manufacturer publishes MTF charts, they are almost without exception not quite truthful in that they typically do not account for distortion correction, which can substantially degrade micro contrast—a pixel stretched from 1.0 pixels to 1.03 or 1.07 pixels (or whatever), micro contrast is visibly degraded, and effective resolving power drops.
