AUTOFOCUS COMES TO SIGMA CINE ZOOM LINE
They are based on the 28-45mm f/1.8 DG DN Art and 28-105mm f/2.8 DG DN Art optics, which we have tested to deliver crisp resolution, soft bokeh and strong flare control across all focal lengths and focus distances. The new lenses are made at Sigma’s Aizu factory in Japan using cutting-edge manufacturing processes. The lenses offer limited focus rotation, clickless aperture rings and 0.8M pitch gears for full compatibility with follow focus rigs and pro cine set-ups. A key innovation is Sigma’s High-response Linear Actuator, enabling fast, near-silent AF with strong subject tracking – ideal for gimbal, handheld or documentary work. Pricing for the new prime and zoom lenses is yet to be announced. sigmauk.com
As pro filmmakers embrace AF but still crave the control of manual cine glass, Sigma has revealed two new cinema lenses that blur the boundaries between stills and movies. The brand is developing two new full-frame cinema zoom lenses – the 28-45mm T2 FF and the 28–105mm T3 FF – as part of its all-new AF Cine Line. These form the company’s first AF-enabled lens series designed specifically for cinema. Sony and Nikon already have similar lenses, but these are servo zooms with slower maximum apertures. Launching in November, the lenses will be available in L-Mount and E-mount versions. Sigma admits that, unlike the Aizu primes, these are modelled after Art lens optical performance with professional cinema mechanics and advanced AF technology.
“All lenses cover a 46.3mm image circle, making them fully compatible with full-frame and large format systems such as Arri Alexa LF and Vista Vision”
