Product Features:
Standard zoom redefined: ultra-wide 20 mm to 70 mm
This versatile, high-performance E-mount lens offers a zoom range that extends from ultra-wide 20 mm to 70 mm in a compact, lightweight model that has been painstakingly designed with no compromises in image quality, AF performance, or movie operability.
Outstanding G Lens image quality
Two AA (advanced aspherical) elements and three ED (Extra-low Dispersion) glass elements simultaneously correct chromatic and spherical aberration for extremely high optical performance right out to the image edges, from ultra-wide 20 mm to 70 mm. Deep, soft bokeh is enhanced by a 9-blade circular aperture and optimally tuned spherical aberration, supporting the creation of beautiful, memorable imagery.
Peak AF performance for stills and movies
Two XD (extreme dynamic) Linear Motors provide high thrust for fast, quiet, smooth focus drive. Improved thrust efficiency1 results in up to a 60% increase in AF speed2, and tracking performance has been improved by as much as two times2 so tracking is reliable and precise. Moving subjects are reliably tracked when shooting continuous stills at up to 30 fps3, and high-frame-rate movie capture is smooth.
Refined movie imagery
Advanced technology reduces focus breathing as well as focus and axial shift when zooming so that distracting image shifts are minimized. This lens has also been designed for quiet operation when shooting movies, with XD Linear Motors and a newly developed aperture unit that dramatically reduce noise and vibration. The breathing compensation function provided in compatible α series cameras4 is also supported.
High-level operability and reliability for any environment
This lens features a dust and moisture resistant design and a fluorine-coated front element that repels contaminants. All controls, including customizable focus hold buttons and independent rings for focus, zoom, and aperture are designed for smooth, versatile control when shooting stills or movies. A focus mode switch makes it easy to switch between autofocus and manual focus on the fly.
Lens Configuration
Impeccable Sony G Lens design emphasizes a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist's vision.
MTF Chart
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
