Autofocus breaks into the cine world
silent focusing, so is ideal for capturing action, working on gimbals or following unpredictable subjects when shooting documentary work. The mechanical build reflects cinema standards, with industry-standard 0.8M pitch gears, a clickless aperture ring and a limited-rotation focus ring. The lens maintains a constant T2 aperture across the zoom range and features an 11-blade diaphragm for smooth out-of-focus rendering. Weighing just 1.2kg/2.76lb, it has a front diameter of 95mm. sigmauk.com
The 28-45mm T2 FF is the first lens in Sigma’s brand-new AF Cine Line which brings autofocus to professional cinema optics. Available in L-Mount and E-mount, the lens represents a major milestone and adapts the optical design of the Sigma 28- 45mm f/1.8 DG DN Art stills lens into a cine housing, yet retains AF, changing from AF to manual focus via a switch on the barrel. This £2599/$3399 Sigma lens combines pro-grade mechanical construction with autofocus using Sigma’s High-response Linear Actuator (HLA). This proprietary system delivers fast, precise and near-
Sigma’s new 20-200mm f/3.5-6.3 DG Contemporary lens is the world’s first 10x zoom lens to start at an ultra- wide 20mm for full-frame mirrorless cameras. Available in E-mount and L-Mount for £799/$999, it has a maximum magnification ratio of 1:2 between 28mm, and 85mm even brings half-macro shooting into play. The lens weighs 550g/1.2lb and measures 115.5mm/4.5in in length, making it a highly portable option. Practical touches include a zoom lock switch to prevent lens creep, a dust- and splash- resistant structure, as well as oil- and water-repellent coatings. Sigma’s engineers have also worked to minimise flare and ghosting, especially in strong backlight. THE 10X ZOOM BREAKTHROUGH
SIGMA PUSHES BOUNDARIES WITH FAST PRIMES
coatings. A magnesium-alloy Arca-Swiss tripod collar provides stability. Alongside it comes the £1299/$1549 35mm f/1.2 DG II Art, succeeding the 2019 lens that was the world’s first 35mm mirrorless prime with such a fast aperture. Launched for E-and L-Mount, the new version has sharper optics, faster AF and a much lighter build. Sigma has cut it by around 30% in weight and 20% in length. A new floating focus system enables the smaller design, while focus breathing is also minimised. The lens uses a mix of aluminium-magnesium alloy and TSC composite. Controls include a lockable and de-clickable aperture ring, assignable AFL button and focus mode switch.
The acclaimed Sigma Art line expands once more with the
lens. Advanced aspherical lenses, a 13-blade rounded diaphragm and thorough correction of chromatic aberration give smooth bokeh from centre to edge. Sigma has fitted it with a dual HLA AF system, guaranteeing the thrust required for large-aperture also includes two assignable AFL buttons, an aperture ring with lock and click options and weather-resistant sealing with oil- and water-repellent telephotos and precise, rapid AF performance.

groundbreaking 135mm f/1.4 DG and 35mm f/1.2 DG DN primes. The tele lens costs £1649/$1899 and is the world’s first autofocus 135mm lens with a maximum aperture of
f/1.4. Available in E- and L-Mount, the 1430g/3.15lb lens is built to give a look even better than its famed 105mm f/1.4 ‘Bokeh Master’, while rivalling the creamy blur of its 200mm f/2 Sports
