Key Features:
- Ultra-wide prime lens is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it provides a 30mm equivalent focal length.
- Bright f/1.8 maximum aperture suits working in difficult lighting conditions and helps to maintain a relatively compact form factor.
- Two AA (Advanced Aspherical) elements help to greatly reduce distortion and spherical aberrations in order to accurately render scenes with a high degree of sharpness.
- Three extra-low dispersion elements reduce colour fringing and chromatic aberrations for improved clarity and colour accuracy.
- A Nano AR Coating has been applied to minimise surface reflections, flare, and ghosting for increased contrast and colour rendering in strong lighting conditions.
- Dual XD Linear Motor system provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control. An AF/MF switch is located on the lens barrel for tactile control over this setting.
- Customisable focus hold buttons are present on the lens barrel for intuitive tactile control and rapid access to select settings.
- Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
- Dust- and moisture-sealed design better permits working in inclement conditions and rubberised control rings benefit handling in colder temperatures.
- Fluorine-coated front element resists dust, moisture, and fingerprints and is easy to clean.
- Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
