More from Sigma in 2013
We're told Sigma will announce a 135mm f/1.8 DG OS Art lens sometime in 2013. There could be up to 3 more Art lenses announced this year. We've previously heard they would be releasing a 24mm f/1.4 DG Art sometime in 2013.
There has been no mention of an f/2 or faster zoom for full frame cameras.
An update to the 50mm f/1.4 could also be on the horizon.
