Additional information:

The Sigma AF 28-70 mm f/ 2.8 EX Aspherical DF  is an all-purpose zoom lens  for 35 mm SLR cameras of popular autofocus systems.

It is the world's smallest lens with such characteristics.

The DF(Dual Focus) system ensures the focusing ring immobility during autofocus operations.

The use of a multiturn spiral in the focusing mechanism eliminates the front lens rotation of the Sigma AF 28-70 mm f/ 2.8 EX Aspherical DF, which makes it cap and filter friendly. A petal hood is included with the lens.
