Product Description
Sirui Swift 20mm F2.4 is the ultra-wide lens of SIRUI's new Swift series, a light and compact full-frame autofocus lens made for everyday carry. Its 20mm view fits landscapes, street photos, interiors and vlogs, and it weighs only about 207 g on Sony E mount.
Ultra-wide view for daily shooting
The 20mm focal length gives a wide view for landscapes, street scenes, group shots and walk-and-talk vlogs, while the small size keeps it easy to carry all day.
Close focus at 0.2m
You can focus as close as 0.2m, so you can get near the main subject, keep the background in frame and show fine detail.
Quick and smooth STM autofocus
An STM motor gives fast and quiet autofocus that helps keep moving subjects sharp, with a switch to change between AF and MF.
Made for video
SIRUI designed the lens for low distortion, natural colour and minimal focus breathing, so the look stays consistent when focus changes in vlogs, short films and time-lapses.
Hands-on controls
A clicked aperture ring gives precise, tactile aperture steps, and the FN button can be assigned to a camera function.
