Sigma 300mm f/2.8 EX DG OS HSM lens leaks at Photokina presentation

Janne Heimonen spotted something interesting in a recent Sigma presentation at Photokina by their CEO Kazuto Yamaki: a listing for a Sigma 300mm f2.8 EX DG OS HSM lens. Sigma currently has only a 300mm f/2.8 EX APO DG HSM lens in their lineup ($3,399). Here is the meaning of Sigma's lens abbreviations:

  • EX - superior build and optical quality
  • DG - for digital SLR cameras
  • OS - Optical Stabilizer
  • APO - Apochromatic
  • HSM - Hyper Sonic Motor
