Boasting maneuverability, this lens is equipped with a hyper-sonic motor for fast, quiet AF performance and intuitive manual focus control at all times. A focus limiter switch also helps increase focus speed and accuracy, and there's also a customizable AFL button and dedicated focus mode switch. In addition, the lens features a rounded nine-blade diaphragm for smooth bokeh quality and the lens housing is also waterproof to accommodate working conditions under adverse conditions.
Part of the Art line of the Global Vision series from Sigma, this lens is designed to achieve truly remarkable optical performance and is ideally suited for creative and artistic applications.
The short telephoto lens is designed for full frame Sony E-mount mirrorless cameras, but can also be used with APS-C models where it provides a focal length equivalent to 157.5mm.
A special Low Dispersion (SLD) element dramatically reduces chromatic aberration and color fringing for enhanced color clarity and accuracy.
A Super Multi-Layer coating has been applied to the lens elements to minimize lens flare and ghosting and help produce images rich in contrast and neutral colors, even in backlighting.
True macro design offers a full-size maximum magnification of 1: 1 with a minimum focus distance of 29.5cm, to suit working with close-up subjects.
The integrated HSM (Hyper Sonic Motor) achieves fast and quiet autofocus performance, which is further complemented by an AF algorithm optimized to produce smoother focusing performance. The HSM also allows manual control of the focus at any time by simply turning the focus ring at any time.
Focus Limit Switch can be used to limit the focus range in three areas for faster and more responsive performance
The manual aperture ring can be decoupled for smooth and quiet aperture switching for the benefit of video applications. In addition, a dedicated aperture ring lock switch can also be used to prevent accidental shift of the aperture setting.
The built-in Auto Focus Lock (AFL) button to which additional functions can be assigned expands the range of operations available on the lens.
The rounded nine-blade diaphragm contributes to a smooth and pleasant bokeh quality.
Weather resistant construction with a brass bayonet that provides improved mounting precision and rigidity.
