Sigma Contemporary 50mm f/2 DG 50mm
A compact 363g weather-sealed all-metal build pairs an f/2 aperture with three aspherical elements and one SLD glass element to suppress aberrations. Tactile knurled manual focus and aperture rings, plus a stepping motor for quiet autofocus, echo Sigma’s cinema lens construction in a portable design. This lens suits street and portrait photographers needing a durable, lightweight 50mm prime for L-mount.
