Sigma Contemporary 20mm f/2 DG 20mm
Weighing just 370g with a weather-sealed all-metal build, this 20mm f/2 prime delivers ultra-wide composition and fast aperture in a compact L-mount package. The STM autofocus enables smooth video pulls, while three aspherical and two ED elements minimize distortion and aberrations across the frame. Best for travel and landscape photographers who need a lightweight, durable wide-angle lens with decent low-light capability for handheld shooting.
