Balancing the optics is a refined exterior design, which features a physical aperture ring, which can be de-clicked or locked, along with a dedicated focus mode switch and AFL button for intuitive and tactile control. For autofocus, a stepping motor is used that maintains a lightweight and compact design while promoting fast and near-silent focusing performance for both stills and video applications. Additionally, the lens features an 11-blade rounded diaphragm for smooth bokeh
quality and the lens housing is also weather-sealed to suit working in inclement conditions.
- As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
- Portrait-length lens is designed for full-frame L-mount mirrorless cameras but can also be used with APS-C models where it provides a 127.5mm equivalent focal length.
- Bright f/1.4 maximum aperture is particularly well-suited for working in available light conditions and provides extensive control over depth of field for isolating subject matter with selective focus.
- Five Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and colour fringing for improved clarity and colour accuracy.
- One aspherical element and four high refractive index glass elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
- A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and colour-neutral imagery, even in backlit conditions.
- Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.
- Manual aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications. Additionally, a dedicated aperture ring lock switch can also be employed to prevent accidental shifting of the aperture setting.
- Built-in Autofocus-Lock (AFL) button which can be assigned additional functions widens the range of operations available on the lens.
- Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
- Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
- This lens is compatible with the optional Sigma UD-11 USB Dock for fine-tuning different lens characteristics and updating its firmware.
