Verdict

The Sigma AF 28mm f/1.8 EX DG leaves us with a mixed feelings. The center resolution of the lens is nothing to complain about, while the borders and corners disappoint especially at large apertures. Vignetting is quite pronounced wide open, but distortion and CAs are well under control.

The bokeh is quite nervous at large apertures, but improves considerably when stopped down a little.

The build quality is a bit of a negative surprise because of the wobbling inner lens tube.

So, it's not an attractive choice for landscape shooters, but because of its very short minimum focus distance it's an interesting lens to shoot close-ups with wide perspectives.

★★★★★ (Landscapes)
★★★★★ (Close-up fun)
Mechanical Quality:
