We first had the chance to see the Sigma AF CINE LINE 28–105mm T3 prototype at IBC 2025, and the launch date has now been set for April 16th, 2026. This full-frame cinema zoom covers a very practical focal range in a single lens and combines cine mechanics with a zoom design more familiar from still photography. This positions the lens as a good option for productions working across a wide focal range without frequent lens changes.

We first covered the lens when Sigma officially announced the development of the 28–105mm T3, and later saw the prototype alongside the company’s autofocus cine zoom concept, which combines traditional cine operation with autofocus. Since then, the lens has been one of the more anticipated additions to the AF CINE LINE, mainly because it brings this focal range into a cinema lens design.

Why the 28–105mm range is interesting

A 28–105mm range covers a large part of everyday shooting. It moves from a moderately wide field of view into a short telephoto, which makes it useful for interviews, documentary work, corporate projects, and smaller narrative productions. In many of these situations, reducing lens changes matters more than using the fastest possible aperture. A zoom that spans this range makes it easier for crews to move quickly while keeping a consistent look, especially when working with limited time or smaller teams.

Within Sigma’s cine lineup, this places the lens between traditional prime sets and larger cine zooms, offering a more compact alternative for many productions.
