The long-rumored Sigma 70-200mm f/2.8 DG DN Sports lens is expected to be announced in the next few weeks - most likely in early October. The date floating online is October 6th, but this is highly unlikely since in the past only Leica and the Chinese brands made any major announcements on a Friday. The lens will be available for Sony E and Leica L mounts. Sigma currently only has a 70-200mm f/2.8 lens for DSLR cameras.
