In May 2016 Sigma patented the 70-200mm f/2.8 DG OS HSM Sports lens, and this lens is now close to being completed – Sigma will announce their Sigma 70-200mm f/2.8 DG OS HSM Sports lens sometime in Q3/Q4 of 2017.
2017 is definitely a busy year for Sigma. At CP+ 2017 Sigma announced four new lenses: Sigma 14mm f/1.8 DG HSM Art, Sigma 135mm f/1.8 DG HSM Art, Sigma 24-70mm f/2.8 DG OS HSM Art and Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary lenses. And the cinema versions of the new Sigma 14mm f/1.8 & 135mm f/1.8 Art lenses will be unveiled later this year.
The detailed specs and price of the Sigma 70-200mm f/2.8 DG OS HSM Sports lens are still unknown. Shipping will not start until the latest four new lenses are shipping in good quantity.
In addition, Sigma will announce a new macro lens and a “400mm f/5.6 DG OS or similar” lens in 2017. That’s a crazy year for Sigma!
