In the grand exhibition of Photokina 2012, Sigma introduces innovative lens lineup. User can configure Sigma lens through special docking and software. Users can fine tune autofocus and change other parameters. It is very helpful to solve Sigma lens front-back focusing.
Sigma also introduces a new concept in categorizing the lens. Sigma divides new lenses into three categories to make it easier for prospective buyers to get the lens they need. Here there are:
- Contemporary: Practical, all around, compact and lightweight lenses : Sigma 17-70mm f/2.8-4 DC Macro OS.
- Art: Lenses for artist in you. Most of these lenses are fix lenses with large aperture : Sigma 35mm f/1.4. Macro lens, tilt-shift, fish eye, will belong in this category.
- Sports: super long telephoto lens, ideal for sports and wildlife photos. Example: Sigma 120-300mm f/2.8 OS HSM
In addition to introducing the above three categories, Sigma also promises a higher quality control.
