Sigma 18-35mm F1.8 DC HSM A Nikon mount lens review: Unrivalled Standard ZoomBy Kevin Carter - Tuesday November 19 2013 Lens Review
When mounted on the 24-Mpix D7100, the Art series Sigma 18-35mm f1.8 DC HSM A is the best performing zoom in our database. With a DxOMark score of 28 points it leads by quite a margin, not only is it well corrected but also the high-speed design permits increased illumination of the APS-C sensor and is an important influence on image quality. However, in terms of peak sharpness it rivals lenses such as the firm’s DX format 50-150mm f2.8 EX DC APO HSM model and the Tamron SP 70-200mm f2.8 Di VC USD.
When benchmarked against current standard zooms, the high-speed Sigma stands out even against the firm’s respected 17-50mm f2.8 EX DC OS HSM model and other premium-quality zooms such as the $1329 AF-S DX Nikkor 17-55mm f2.8G IF-ED and newer full-frame AF-S Nikkor 16-35mm f4G ED VR.
