Sigma 24mm f/1.4 DG HSM specification: Fast f/1.4 aperture and Sigma HSM autofocus motor
Sigma has a good track record for delivering first-class wide-angle lenses with its APS-C format 10-20mm f/3.5 or full frame 35mm f/1.4 DG HSM both securing a great reputation among enthusiasts and professional photographers alike. It comes as no surprise then that Sigma has announced a new wide-angle in its latest Art, or A, range of optics, this time with a wide f/1.4 maximum aperture for creating artistic bokeh and blur effects.
The DG abbreviation in the title indicates that the new 24mm is designed for full-frame DSLRs such as the Canon 5DS or Nikon D800E, but the lens will still work on APS-C sensors, where it offers an equivalent 36mm or 38.5mm focal length (depending on your camera manufacturer). The lens also features a Sigma HSM motor for super-fast autofocus, and the optional $60 Sigma USB dock makes it possible to plug your new glass into a computer to update the firmware, or to fine-tuning settings such as focus point and full-time manual focus.
With an optical arrangement of 15 elements in 11 groups, the new Sigma 24mm f/1.4 DG HSM incorporates FLD and SLD elements to reduce chromatic aberration, along with lens coatings to reduce flare and ghosting and to deliver high-contrast images. Given the outstanding performance of its 35mm f/1.4 Art sibling, we look forward to putting the new Sigma 24mm f/1.4 Art through its paces as soon as we can.
Sigma 24mm f/1.4 Art will become available next month for the street price of $849.
