Sigma has added a compact gem of a lens to its Contemporary series, which is known for versatile, lightweight lenses, the kind that serve well on vacation or in general day-to-day photography. With the new 18-50mm f/2.8 DC DN lens, Sigma’s first APS-C size mirrorless zoom lens available for Sony E-mount and Leica L-mount APS-C cameras, Sigma has outdone itself, offering an extremely small lens with a 27-75mm equivalent focal length range and an f/2.8 constant maximum aperture.
Normally, an f/2.8 lens with these focal lengths would be much bigger and, having had the chance to use this lens with my Sony a6500 mirrorless camera, it is hard to underestimate the pleasure and the advantages of having such “workhorse specs” (27-75mm f/2.8) in a barrel that weighs just 10.2 oz (290 grams) and is only 2.9" (7.5cm) long at the wide-angle setting. It is an ideal match for APS-C size cameras, very easy to control and to adjust zoom with one hand, which is helpful for smooth videography.
