Sony SEL FE 20-70mm f4 G Lens
Compact, lightweight standard zoom covers ultra-wide 20 mm to 70 mm
Redefines the standard zoom category with a focal length range that extends from ultra-wide 20 mm to 70 mm in a remarkably compact, lightweight full-frame lens with maximum aperture constant at F4.
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 efficiency results in up to a 60% increase in AF speed, and tracking performance has been improved by as much as two times so tracking is reliable and precise. Moving subjects are reliably tracked when shooting continuous stills at up to 30 fps, 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 minimised. This lens has also been designed for quiet operation when shooting movies, with XD Linear Motors and a newly developed aperture unit that dramatically reduces noise and vibration. The breathing compensation function provided in compatible α series bodies4 is also supported.
