With the new 70-200mm F2.8 DG DN OS Sports, Sigma is now also offering its standard telephoto zoom for mirrorless mounts. At the start, these are specifically Sony E-mount as well as for all cameras of the L-mount alliance, i.e. Leica, Panasonic, Blackmagic, Sigma, DJI (and Astrodesign).
The most important new functions of the 70-200mm F2.8 DG DN OS Sports include the new HLA autofocus motors (High-Response Linear Actuator), which were previously only used on the 60-600mm F4.5-6.3 DG DN OS Sports, as well as the optical image stabilizer equipped with the new OS2 algorithm, which, according to Sigma, compensates for up to 7.5 f-stops at 70mm.
The optical design consists of 20 elements in 15 groups. The dimensions are 90.6 mm x 205.0 mm for L-mount and 90.6 mm x 207.0 mm for Sony E-mount.
Interesting for filmmakers: As the new Sigma 70-200mm F2.8 DG DN OS Sports has both internal focusing and an internal zoom, the overall length always remains the same. So if you are traveling with gimbals, you can count on a relatively constant weight distribution over the entire focal length. Sigma also points out that the constant zoom length should also provide better protection against dust and splash water than comparable lenses, whose barrel retracts and extends when the focal length changes (but is also somewhat larger during transportation). Another interesting feature for filmmakers: the mechanical aperture ring can be deactivated at the touch of a button.
The weight of the new Sigma 70-200mm F2.8 DG DN OS Sports is 1,335 g (1,345 g for L-mount). According to Sigma, three materials were used in the construction: magnesium, carbon fiber-reinforced plastic and TRC (thermo-stable composite). The aperture consists of 11 blades and, according to Sigma, should ensure a particularly pleasant bokeh. A 77mm version is used as the filter thread.
The new Sigma Zoom also features a whole range of additional switch-based functions. These include custom mode, AF/MF, focus compensation, stabilization modes including on/off and three AE-L buttons, which can be freely assigned by the user.
