A new wide angle
We're told that Sigma almost has a 24mm f/1.4 DG HSM Art lens ready. An announcement could come this year or early next year. The build quality and performance will rival that of the Sigma 35mm f/1.4 DG HSM we're told. The lens will be a little more expensive, but Sigma hopes to keep it under $1000 USD.
We were also told that Sigma is planning something “big” for Photokina 2014 a year from now. It was hinted that it could be new super telephoto lenses.
