The pictures below illustrate the angles of view on FX (35mm full frame) and DX camera bodies:
Extremely even image quality across the frame; even on FX; Improved image quality over 50mm F1.4D at large apertures; Exceptional image quality when stopped down; Essentially no lateral chromatic aberration; Near-silent AF-S focus with full-time manual override
Slightly soft at large apertures; Somewhat susceptible to flare; Longitudinal (bokeh) chromatic aberration; most visible at large apertures; Vignetting at large apertures on full frame (essentially disappears by F2.8; Slower autofocus than the screw-drive AF-Nikkor 50mm F1.4D
