Sigma's CEO Kazuto Yamaki has spoken in depth about the development of a pair of new lenses in a Youtube interview with cinematography specialists LensVid at the IBC 2024 trade show. IBC – or International Broadcasting Convention – is an annual show held every September in Amsterdam, the Netherlands. The lenses in question are the Sigma 28-45mm T2 Cine and Sigma 28-105mm f/2.8 DG DN Art.
First up, the Sigma 28-45mm T2 Cine lens is a prototype, or 'concept' lens as Sigma prefers it, which was shown mainly to garner feedback from customers. It is based on the full-frame Sigma 28-45mm f/1.8 wide-to-standard zoom lens aimed at stills photographers, essentially shoehorning the same optics into a cine-style housing, with full autofocus but also with the oversized mechanical geared focus rings favored by videographers.
