We had already mentioned 
here the upcoming Sigma 70-200mm F2.8 DG DN OS Sports. However, at the start of Sigma's teaser campaign the technical information was still rather sparse. Now, in best teaser style, Sigma has added (a little) more:
The Sigma 70-200mm F2.8 DG DN OS Sports has 15 groups of 20 optical elements (6 FLD, 2 SLD, 3 Aspherical Elements) and comes with a filter thread that accepts 77mm screw filters.
The available mounts (Sony E- and L-mount) had been known before - Sigma now gives the weight as 1,345g (L-mount) and 1,335g (E-mount).
Also new are the dimensions of 90.6 mm × 207.0 mm for the Sony version and 90.6 mm × 205.0 mm for the Sigma, Panasonic, Leica, Blackmagic and DJI versions.
Still missing are MTF charts and, of course, prices, which we will pass on as soon as they are available.
