Kestrel 35
A 35 mm f/1.4 manual-focus lens.
Full frame · Sony E and Nikon Z
Eleven blades, rounded.
Curved blade edges keep the opening close to a circle as you stop down, so out-of-focus highlights stay round for longer.
270° of focus throw.
0.3 m to infinity is spread over three-quarters of a turn, which gives fine control when you focus by hand. The distance scale is engraved in metres.
Eight elements in six groups.
Two aspherical surfaces and one extra-low-dispersion element correct the spherical aberration and colour fringing a fast 35 mm is prone to.

The lens reports aperture and focus distance to the camera, so both are recorded in EXIF and in-body stabilisation sets itself for 35 mm. Shown: the E-mount version.

Watch the lights.
Out-of-focus highlights take the shape of the opening: near-circles wide open, with the blade edges showing as you stop down. Point lights in focus grow rays, and an odd number of blades gives twice as many, so eleven blades draw twenty-two.
