Sigma 17-70mm f/2.8-4 DC Macro OS HSM C (Nikon) review: update to popular standard zoom lensBy Kevin Carter - Friday June 21 2013 Lens Review
Designed solely for APS-C format DSLRs the $499 17-70mm f/2.8-4 DC Macro OS HSM C (27-112mm equivalent) is the first of Sigma’s Contemporary C-series zooms and the update to the popular 17-70mm f/2.8-4 DC Macro HSM. Read on to see how this Nikon mount version performed in our labs.
With a classy looking outer finish, new optical construction of 16-elements in 14 groups including image stabilization and an ultrasonic type motor, and a $100 premium the Sigma 17-70mm f/2.8-4 DC Macro OS HSM C replaces the previous $399 17-70mm f/2.8-4 DC Macro HSM model. This review is based on the Nikon mount version, the evaluation of the Canon fit model can be found here.
