First Looks at Sigma 30mm f/1.4 DC HSM Lens Image Quality

Standard test results (ISO 12233 resolution chart/image quality, flare, distortion, vignetting, specs & measurements) have been added to the Sigma 30mm f/1.4 DC HSM Lens review page.

The new Sigma 30mm f/1.4 DC HSM Lens, the "| A" version, is a significant upgrade from the Sigma 30mm f/1.4 EX DC HSM Lens, the "EX" version, in terms of build quality. Unfortunately, the image quality has not been so upgraded.
