The Sony FE 20-70mm f/4 G OSS Lens is a wide-to-telephoto zoom lens that provides an ultra-wide angle of view for full-frame E-mount mirrorless cameras. The constant f/4 maximum aperture makes this lens useful in low light and provides shallow depth of field control. This lens features a fast internal focusing system, along with a rounded 9-blade diaphragm for smooth defocusing effects.
The optical design incorporates three ED (Extra-low Dispersion) elements, one ED aspherical element, and one standard aspherical element to minimize chromatic aberrations and distortion throughout the zoom range. Two AA elements are also featured to reduce astigmatism, curvature of field, and sagittal coma flare as well as to suppress flare and ghosting for greater contrast when working in strong lighting conditions. Fluorine Coating has also been applied to each lens surface to repels water, dust, fingerprints, and other contaminants.
The internal focusing system utilizes an inner focusing mechanism driven by a linear motor to focus quickly and quietly, while maintaining consistent focus position during manual focus adjustments. Two XD (extreme dynamic) linear motors are also used for precise control of the aperture, which allows for more accurate exposure control.
Product Features in Detail
From ultra-wide 20 mm to 70 mm
With an unprecedented2 ultra-wide 20 mm to short-telephoto 70 mm zoom range, this versatile lens is an excellent choice for a wide range of movie and still subjects. The ultra-wide 20 mm end of the zoom range maintains a wide angle of view when shooting movies with a 16:9 or 2.35:1 aspect ratio that reduces view angle.
Outstanding G Lens image quality
With two AA (advanced aspherical) elements, one aspherical element, three ED (Extra-low Dispersion) glass elements, and one ED aspherical element, this state-of-the-art lens design corrects both chromatic and spherical aberration for high optical performance right out to the image edges, from ultra-wide 20 mm to 70 mm.
Excellent close-up performance
AA (advanced aspherical) elements help to achieve a minimum focus distance of 0.3 meters (wide) to 0.25 meters (telephoto) when using AF, and 0.25 throughout the zoom range when focusing manually. Maximum magnification is 0.39x for detailed close-ups. Close focus makes it easy to maneuver around small subjects to find the idea angle.
Constant F4 maximum aperture
A constant F4 maximum aperture offers greater flexibility in choosing apertures at any focal length. The selected aperture remains constant throughout the zoom range. There is no need to use extreme ISO settings at the telephoto end of the range, and high shutter speeds can be used as needed to achieve the desired effect.
Peak AF performance for stills and movies
Two XD (extreme dynamic) Linear Motors achieve fast, quiet, smooth focus drive with up to 60% higher AF speed3 and up to two times3 better performance while tracking3 for reliable, precise tracking. Moving subjects are reliably tracked when shooting continuous stills at up to 30fps4, and high-frame-rate movie capture is smooth.
Compact, lightweight, mobile design
This compact, lightweight lens combines state-of-the-art optical design with Sony's high-thrust XD (extreme dynamic) Linear Motor technology. Used with a compact mirrorless body, it can deliver superb image quality in any situation at focal lengths from ultra-wide to short telephoto. A great choice for shooting with minimum gear.
Refined movie imagery
Advanced technology reduces focus breathing as well as focus and axial shift when zooming so that distracting image shifts are minimized. XD Linear Motors and a newly developed aperture unit dramatically reduce noise and vibration when shooting movies. The breathing compensation function provided in compatible a series bodies5 is also supported.
Aperture ring with click ON/OFF switch
An independent aperture ring offers direct, intuitive aperture control. A click ON/OFF switch allows the aperture click stops to be turned off when smooth, seamless operation is required.
Active Mode6 supports ultra-wide images
Active Mode6 image stabilization in a series cameras works effectively at the ultra-wide 20 mm end of the zoom range, providing excellent image stabilization performance while maintaining a wide angle of view. This can be particularly useful for shooting smooth, stable handheld footage while walking.
Focus hold buttons and focus mode switch
Customizable focus hold buttons are provided in two locations for easy access and control. Other functions can be assigned to the focus hold button from the body menus to match shooting needs. A focus mode switch makes it possible to switch between autofocus and manual focus on the fly, to quickly adapt to changing shooting conditions.
Dust and moisture resistant design7
A dust and moisture resistant design7 provides extra reliability for outdoor use in challenging conditions.
Fluorine front element coating
The front lens element features a fluorine coating that repels fingerprints, dust, water, oil, and other contaminants, while making it easier to wipe off any contaminants that do become attached to the lens surface.
