Key Take-Aways:

The SG-image Chasing the Wind 50 T1.4 is a manual-focus full-frame cine prime with a T1.4 to T16 stepless aperture ring, 10 aperture blades, an 82 mm filter thread, a 0.5 m minimum focus distance, a 1:7.7 maximum magnification, a 44.2 degree diagonal field of view and 10 elements in 8 groups. The maker lists a metal barrel, a multi-tooth gear transmission and zero focus breathing, a weight of 830 g and a size of 91.2 mm across by 92 mm long, and sells it for $499 in the L-mount selection; its spec image lists E and L mount, and the store also sells a Z version. SG-image says all four lenses in the Chasing the Wind series share the same fast T1.4 aperture and an identical form factor, shape and weight, so lenses can be swapped on a gimbal or rig without re-balancing. As of Oct 2026 few reviews have been written, so none are linked here, and there is not enough independent coverage to say how it performs.

From SG-image:

> The "Chasing Wind Series" of cine lenses, with its 25mm, 35mm, 50mm, and 75mm focal lengths, is designed for filmmakers who need both premium optical performance and a streamlined workflow.

> All lenses in the series share the same fast T1.4 aperture, allowing for exceptional low-light performance and the ability to create beautiful, shallow depth of field with cinematic bokeh. Crucially, they are engineered with the exact same form factor, shape, and weight. This means you can swap lenses on a gimbal, or other camera rig without needing to re-balance, saving valuable time on set.

SG-image publishes one set of figures for all mounts and for all four lenses in the series for the aperture range, blade count, filter size, weight and dimensions (830 g, 91.2 x 92 mm); the focus distance, magnification, field of view and lens construction are the maker's own 50 mm column. The maker gives the field of view as 44.2 degrees; the frontmatter rounds it to 44, and the 1:7.7 magnification is entered as 0.13. The page address ends in "-copy", but its spec image is the same four-lens table, with a 50 mm column.
