Sony Imaging Solutions is pleased to announce FE 20-70mm F4 G (SEL2070G) lens. An industry first, SEL2070G redefines the standard zoom lens by extending to an ultra-wide 20mm field of view while maintaining its range to 70mm mid-telephoto. Even with this unprecedented range of focal length, SEL2070G is remarkably compact and lightweight – ideal for a wide range of still and movie applications.
With an unprecedented1 ultra-wide 20 mm to mid-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 field of view.
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.
Two XD (extreme dynamic) Linear Motors achieve fast, quiet, smooth focus drive with up to 60% higher AF speed and up to two times better performance while tracking for reliable, precise tracking. Moving subjects are reliably tracked when shooting continuous stills at up to 30 fps3, or up to 4K 120p with alpha compatible cameras.
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 α series cameras4 is also supported.
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 camera, it can deliver superb image quality in any situation at focal lengths from ultra-wide to short telephoto. A great choice for shooting with a highly mobile and lightweight setup.
AA (advanced aspherical) elements help to achieve a minimum focus distance of 11.8” (30 cm - wide) to 9.8” (25 cm - telephoto) when using AF, and 9.8” (25 cm) 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 ideal angle.
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.
The deep, soft bokeh available with full-frame image sensors is further enhanced by a 9-blade circular aperture and optimally tuned spherical aberration. All of this supports the creation of impressive, memorable imagery.
Active Mode image stabilization in α 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.
An aperture ring provides direct, rapid control. The aperture ring click stops can be turned ON to provide tactile feedback when shooting stills, or OFF for smooth, silent control when shooting movies. There is also an iris lock switch that prevents the aperture ring from being accidentally moved between the [A] and F4 ~ F22 settings
Two customizable focus hold buttons are provided for easy access and control at most any orientation. Several alternative functions can be assigned from the camera’s menu.
Three ED (Extra-low Dispersion) glass elements plus one ED aspherical glass element significantly reduce chromatic aberration for sharp reproduction without color bleeding.
Linear Response MF ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise enough for rack focus effects when shooting movies. This feature also works effectively with the AF Assist function in cameras such as the α7 IV and FX6, giving creators enhanced artistic control.
Instantly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you or decide to take control and manually focus on the precise point you choose.
The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface.
An updated dust and moisture resistant design6 provides extra reliability for outdoor use in challenging conditions. Silicon seals around buttons and switches and a rubber gasket around the lens mount greatly reduce the likelihood of dust and moisture incursion.
The SEL2070G accepts standard 72 mm screw-on filters for expanded creative freedom – even with its ultra-wide capability. Thanks to its internal focus system the filter ring does not rotate while focusing, facilitating the use of circular polarizing filters for landscape photography or variable ND filters for movies.
