28 – 76mm zoom T2.6 PL
The mid-range heart of the Optimo Lightweight trio.
The 28-76mm covers the focal lengths where most cinematographers live (wide enough for medium shots, long enough for close-ups) at a constant T2.6 in a 1.92kg package. Like its siblings, optical performance rivals dedicated primes: exceptional contrast, beautiful bokeh, resolution that holds on 6K and 8K sensors. Same 186mm barrel and weight as the 15-40, shared centre of gravity across the range: swap lenses on a Steadicam rig in seconds without rebalancing.

Talking points
The Steadicam operator’s desert-island zoom: covers 28-76mm at prime-matching T2.6
Identical weight (1.92kg) and dimensions to the 15-40: true drop-in lens swaps on rigs
Compatible with Optimo 1.4× and 2× extenders for extended reach when needed

Heritage
Origin
The 28-76mm followed the 15-40mm into the Optimo Lightweight line in 2007, and many consider it the lens that defined the modern compact cinema zoom category. Alongside the 15-40mm and 45-120mm, it forms a matched trio where every lens shares the same centre of gravity and 114mm front diameter, an Angénieux innovation that changed how Steadicam operators work. The three-zoom set covers 15–120mm at T2.6–T2.8 in under 6kg total. Temperature compensated, compatible with Optimo extenders, and available in PL, Panavision, and EF mounts.
