    28mm · f/1.8

    Overview

    The Sigma 28mm F1.8 EX DG Aspherical Macro offers excellent center sharpness from f/2.8 and gorgeous bokeh, but suffers from soft corners on full frame and weak performance wide open. Build quality is solid with a smooth focusing ring that doubles as an AF/MF switch, though the lens is heavy (16.9 oz) and autofocus can be noisy and unreliable. It suits users wanting a fast wide-angle prime for APS-C cameras or macro-capable close-ups, but alternatives like the Sigma 30mm f/1.4 may be better optically.
