Nikon's approach has been, traditionally, to produce a much larger than format coverage, extremely flat field, low distortion lens and offset it keeping the subject and image planes parallel. The more versatile Minolta approach had been to vary the curvature of the focal plane with an internal floating group to best optimize non convergence or divergence of image parallel straight lines. | This [[Zeiss]] approach distortion control correction should not be confused with [[Minolta]]'s or [[Nikon]]'s architectural lens application approaches It offers a fine tweaking adjustment to apparent pincushion/barrel distortion.
