It’s been the source of much speculation over the past few months, but now it’s official. Sigma has announced the new 70-200mm f/2.8 DG DN OS Sports lens (buy here). Designed for mirrorless cameras, it’s available for Sony E and Leica L mounts.
The new lens offers up to 7.5 stops of image stabilisation and rugged construction. It has fast AF motors and an inner zoom mechanism that doesn’t affect lens length.
