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
