An ultra-wide prime with an emphasis on portability, the Sony E-mount 24mm f/3.5 DG DN Contemporary Lens, from Sigma, is a versatile and highly compact lens well-suited to a variety of shooting tasks. Its sleek profile makes it ideal for walkaround shooting, especially for hiking or travel landscapes, as well as street and reportage applications. Distinguishing itself from other wides, too, it features a 1:2 maximum magnification ratio and 4.25″ minimum focusing distance for working with close-up subjects. Its optical design features both aspherical and low dispersion glass elements, which suppress a variety of aberrations and distortions for well-controlled and accurate rendering. Also, a Super Multi-Layer Coating helps to reduce ghosting and flare for improved color fidelity and contrast.
In regard to focusing, this lens uses a stepping motor for quick and quiet AF performance that suits both photo and video applications. As an I Series lens, too, this lens features a manual aperture ring and all-metal barrel constriction for enhanced tactility. Additionally, there is a rounded seven-blade diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.
