Sigma 14mm f/2.8 EX D HSM Lens for Nikon F

The Sigma 14mm f/2.8 EX D HSM is a full-frame ultra-wide prime lens built for Nikon’s F-mount SLR and DSLR system and part of Sigma’s EX series, representing Sigma’s higher tier of optical and mechanical standards at the time of its production. At 14mm with an f/2.8 maximum aperture, it delivers an expansive ultra-wide field of view well suited to landscape, architecture, interior, astrophotography, and creative wide-angle work where maximum scene coverage is desired. The D designation indicates distance information transmission to compatible Nikon bodies for more accurate metering and flash exposure calculations, and the HSM ultrasonic motor delivers fast, quiet, and responsive autofocus performance without requiring a body-side focus motor. The EX series construction reflects Sigma’s emphasis on build quality and optical performance at this tier of their lineup.
