Sigma Goes Wide and Long With Its T1.3 Aizu Large-Format Lens Series
Sigma has introduced three new lenses for its Aizu large-format cinema lens series, bringing the line to 11 lenses total with 21mm, 100mm, and 125mm options. Let’s look at these new additions.
Sigma Aizu Lenses
Sigma is going wide and long with its popular Aizu large-format series of cinema prime lenses, adding three new options. All three new lenses continue the legacy of the previous eight options and still feature an ultrafast T1.3 aperture, a 46.3mm image circle, and the same quality.
Top options for those shooting on ARRI PL and Sony E mounts, these new lenses should expand the range for diverse projects and be great options for high-end DPs looking for lenses for their cinematic projects.
Let’s check out the new options.
New Sigma Aizu Lenses
So, when Sigma first introduced the Aizu Prime line last summer, it turned some heads as the world’s first cinema lens line to feature T1.3 across all focal lengths. That promise has been kept as these new lenses, a 21mm, a 100mm, and a 125mm, keep the tradition going while also offering an ultrafast T1.3 aperture.
These three lenses join the current lineup, which already includes eight lenses at 25, 27, 32, 35, 40, 50, 65, and 75mm focal lengths. And while the 21mm is nice to see, and what we’ll explore for specs below, it’s really the telephoto side that’s getting most of the expansion, and is arguably most impressive with keeping the same T1.3 aperture going.
Overall, these lenses are proving to be a popular pick for filmmakers and DPs working with full-frame and Super 35 sensors, as well as for large-format cameras—which are having a bit of a moment right now.
