Sigma Releases All the FullFrame Lenses Weve Been Waiting For mm f mm f mm OS and Fstoppers

“Today is the day that Sigma fills out its Art-series lens lineup to offer what could easily be considered everything you’d really need since its most recent release of the 85mm f/1.4 Art. Four new full-frame lenses cover the gamut from an ultra-wide, ultra-fast 14mm f/1.8 Art, a similarly fast 135mm f/1.8 Art portrait lens, to the wedding photographer’s favorite 24-70mm f/2.8 Art and sports shooter’s 100-400mm f/5-6.3 Contemporary “compact” super-zoom. If you’ve been waiting for that next Sigma lens, odds are it’s one of these.
The 14mm f/1.8 DG HSM Art features the “largest glass mold (80mm) in the industry,” contributing to less flare, ghosting, and distortion. Edge-to-edge sharpness and great chromatic aberration control is also promised, which gives hope to astrophotographers that have been waiting quite some time for a high-end, fast, ultra-wide lens such as this.
Sigma’s 135mm f/1.8 DG HSM Art features a new focus motor that promises increased torque and overall performance with the addition of a focus limiter to optimize the experience in various situations.
The 24-70mm f/2.8 DG HSM OS Art is built with a metal barrel for durability and composite internal materials for less variation in thermal expansion and contraction. The lens’ design also incorporates a new optical stabilization (OS) system as well as a thicker center glass design that Sigma says helps provide amazing bokeh.
Finally, the dust- and splash-proof Sigma 100-400mm f/5-6.3 DG HSM OS Contemporary features a push/pull zoom function in addition to a standard twist-zoom design. A macro feature offers up to a 1:3.8 reproduction ratio. (UPDATE: the standard twist-zoom function is the main method of zoom, but for those in a hurry for a quick adjustment, a push/pull mechanism is also incorporated).”
