Optical Performance
G Lens Optical Construction
Two Advanced Aspherical elements minimize distortion and spherical aberrations, ensuring high-resolution rendering across the frame. Three Extra-Low Dispersion elements help suppress chromatic aberrations and color fringing for improved clarity and color accuracy.
Coating Technologies
Nano AR Coating reduces flare, reflections, and ghosting for increased contrast in strong lighting. A Fluorine-coated front element repels moisture, dust, and fingerprints and is easy to clean.
Aperture & Bokeh
The bright f/1.8 maximum aperture performs well in low-light conditions and enables shallow depth-of-field effects. A rounded 9-blade diaphragm produces smooth, natural bokeh.
Autofocus and Handling
The Dual XD Linear Motor AF system provides fast, quiet, and precise autofocus suitable for both stills and video. Manual focus control benefits from Sony’s Linear Response design, while a Focus Hold button and AF/MF switch provide tactile on-lens control.
The aperture ring can be de-clicked for smooth, silent adjustments—ideal for video shooters. Despite being an ultra-wide design, the lens accepts standard 67mm front filters, making creative control simple and versatile.
Compact, Portable Design
Weighing only 373 g, this lens is an excellent choice for travel, gimbal use, and vlogging setups. Its dust- and moisture-resistant design supports reliable shooting in challenging environments, while rubberized rings enhance usability in cold conditions.
