    24mm · f/1.8

    Overview

    The Sigma 24mm F1.8 EX DG Aspherical Macro offers sharp center performance wide open, with notable corner softness on full-frame that improves when stopped down. On APS-C, corner sharpness is good from f/2.5. Build quality is solid with a nice heft, though the front barrel may wobble and lacks weather-sealing. Autofocus is slow and can hunt in low light. Chromatic aberration is present but manageable. Its unique combination of wide angle, fast aperture, and 1:2.7 macro capability suits photographers wanting creative close-ups and low-light versatility.
