Sigma 18-50mm f/2.8 DC DN Contemporary Lens (Canon RF)

The Sigma 18-50mm f/2.8 DC DN Contemporary is an APS-C standard zoom lens built natively for Canon’s RF-S mount mirrorless system and part of Sigma’s Contemporary series. Covering a focal range equivalent to approximately 29-80mm in full-frame terms with a constant f/2.8 maximum aperture throughout, it addresses a practical everyday shooting range from moderate wide-angle through short telephoto suited to travel, portrait, street, and general-purpose photography. The constant f/2.8 aperture provides consistent light gathering and depth of field characteristics across the entire zoom range, and a stepping motor autofocus system delivers quiet and smooth focusing performance suitable for both stills and video use. The compact and lightweight native mirrorless design takes advantage of the shorter flange distance to achieve a notably smaller form factor than comparable DSLR-era f/2.8 standard zooms.
