de­liv­ers an eye-pop­ping view­ing angle

You could be for­given for think­ing that this is a DX­for­mat lens, con­sid­er­ing its min­i­mum fo­cal length. In fact, it’s an FX lens that de­liv­ers an as­ton­ish­ing max­i­mum view­ing angle of 122 de­grees, leav­ing the Nikon 14-24mm and Tam­ron 15-30mm in its wake. The built-in lens hood pre­cludes the use of screw-in fil­ters, but at least the two-part hood en­ables the use of 82mm fil­ters at the long end of the zoom range.

Top-qual­ity glass in­cludes four FLD (Flu­o­rite-grade Low Dis­per­sion) el­e­ments, one SLD (Spe­cial Low Dis­per­sion) and four as­pher­i­cal el­e­ments. Build qual­ity also feels im­pres­sive.


The ring-type ul­tra­sonic aut­o­fo­cus sys­tem is fast and quiet, while sharp­ness and con­trast are very nearly as im­pres­sive as from the Nikon 14-24mm lens. The Sigma does ex­tremely well to main­tain edge sharp­ness, con­sid­er­ing its in­cred­i­bly wide view­ing angle. To get the same view­ing an­gles on your DX cam­era, the Sigma 8-16mm is es­sen­tially the same lens in APS-C for­mat.
