This is the first ‘Sports’ lens to be released for mirrorless cameras and is targeted at sports and wildlife photographers. Its optical design (shown below) contains 25 elements in 15 groups  and includes four ‘FLD’ (fluorine-like low dispersion) and two ‘SLD’ (special low dispersion) elements plus a Super Multi-Layer coating to suppress ghosting and flare.

Focusing is driven by a stepping motor and the lens boasts internal stabilisation that claims up to four stops of shake reduction. A nine-bladed iris diaphragm closes to produce a circular aperture for attractive bokeh. The minimum aperture ranges from f/22 to f/29, while the minimum focus is from 58 to 280 cm, producing a maximum magnification ratio of 1:2.9 at 180mm. The lens is threaded to accept 95 mm diameter filters. It is 263.6 mm long with a diameter of 109.4 mm and weighs 2.1 kilograms.

The US MSRP is $1499 listed at on Sigma America’s website. It has yet to be listed on Sigma’s Australian website, although the DSLR version, which was released in 2014, is listed at AU$2699 (but is currently shown as out of stock).
