Super Telephoto ART Calibre Lenses
We’re told Sigma is working on new 300 & 400 f/2.8 OS lenses as well as new 500 & 600 f/4 OS lenses. The lenses would incorporate Sigma’s new philosophy on quality, but at a much lesser price than the Canon or Nikon counterpart.
We could see an announcement on multiple large lenses sometime in 2014.
