Compact Mid-Telephoto Portrait Prime

Perfect for portraiture, the Sigma 90mm f/2.8 DG Contemporary Lens is an especially compact mid-telephoto prime offering a selective field of view and modest maximum aperture that's an ideal combination for headshots, group shots, close-up shots, and compressed landscapes while remaining nimble enough for everyday shooting.

The 90mm focal length is a classic narrow field of view that flatters portrait subjects and the f/2.8 maximum aperture is bright enough for depth of field control and working in available lighting without adding unwanted weight and size to the lens design. Alternatively, the compact 90mm is also a beneficial lens for landscape shooters looking to make more condensed and focused compositions and highlight specific subjects from a distance.
