Designed exclusively for APS-C mirrorless cameras
The lens has been designed exclusively for APS-C mirrorless cameras, resulting in a compact, lightweight body weighing just 340g*. It also features a quiet, high-speed stepping motor that can lock onto subjects quickly and can be used with AF modes such as focus tracking and eye detection. Use the large focus ring to fine-tune focus with Dynamic Manual Focus (DMF). The lens also supports switching between non-linear and linear focusing when customised using the SIGMA USB DOCK UD-11 (sold separately / for L-Mount only). It is also compatible with AF assist functions found on compatible cameras (E-mount only).
Expands the range of APS-C format F1.4 prime lenses
With the addition of the 23mm F1.4 DC DN, the SIGMA Contemporary line now has four APS-C format F1.4 prime lenses. Together they work perfectly as a cohesive ultra-wide aperture set, collectively weighing less than 1.5kg. This means users can build a lightweight mirrorless camera system that delivers superb consistency in image quality, colour accuracy and character.
