    50–150mm · f/2.8

    Overview

    The Sigma 50-150mm F2.8 EX DC APO OS HSM offers a versatile focal range with f/2.8 aperture and image stabilization, but reviews are mixed. Optical performance is praised by some as sharp even wide open with excellent bokeh, while others report severe front-focus issues making it unusable until f/5.6–f/11. Build is solid but heavy, and AF can be spotty. It suits APS-C shooters wanting a stabilized fast zoom, but sample variation is a major concern.
