Congratulations to SIRUI; its SIRUI Vision Prime 1 T1.4 Full Frame Cine Lens Series is Videomaker’s pick for the Best Lens Series at NAB 2025.
Designed for mirrorless camera users, the lens features a 46 mm image circle intended for full-frame sensors, including open gate formats. Let’s take a closer look at Videomaker’s NAB 2025 Best Lens Series.
Full-frame coverage and aperture
One key element of this lens is its T1.4 aperture. According to SIRUI, the design includes an 18-blade aperture, which can help create a circular bokeh effect. For those looking to shoot in low light or achieve shallow depth of field, the wide aperture may be useful.
The lens also has a minimum focus distance of 16.9 inches.
Optical construction
The Vision Prime 1 lens is built with aspherical glass elements and high-refractive index materials. These features are said to reduce chromatic aberration and distortion, which can be important for video work, especially in high-resolution settings.
Also, SIRUI’s multi-layer nano coating is designed to limit flares and ghosting. The company reports that focus breathing is controlled, which could help maintain consistent framing during rack focus.
Focus throw and gear positioning
Filmmakers might appreciate the 270° focus throw, as it can offer more precise control when pulling focus. Both the aperture and focus rings are stepless, which may allow smooth transitions without sudden changes in exposure.
Additionally, SIRUI has made an effort to keep gear positions uniform across its Vision Prime 1 series. This approach might let users swap lenses without adjusting follow focus or other accessories.
Mount options and build
SIRUI’s latest lens ships with a Sony E-mount but includes adapters for Canon RF, Nikon Z and Leica L. The aluminum alloy body weighs around 1.3 pounds. It features a 67 mm front filter thread and has markings in both imperial and metric units.
Pricing and availability
The SIRUI Vision Prime 1 T1.4 Full Frame Cine Lens Series is out now for $649 for each lens, or $1,899 for the full set.
