SEL FE 20-70mm
f/4.0 G E-Mount Lens

Standard zoom redefined: ultra-wide 20mm to 70mm

Extend the range of the standard zoom lens to 20mm for wide field of view required to include yourself, your friends and the background with G series resolution and naturally rendered bokeh.  Fast, precise, silent autofocus together and advanced optics provide peak performance for stills and video.

Key Features:

  • Unprecedented 20 – 70mm full-frame standard zoom with 20mm ultra-wide field of view
  • Outstanding G Lens image quality with corner-to corner high resolution at all focal lengths
  • Optical design includes 2 advanced aspherical and 3 Extra-low Dispersion elements
  • Two XD (Extreme Dynamic) linear motors results in fast, precise and quiet AF
  • 9-blade circular aperture for naturally rendered bokeh
  • Refined movie imagery with minimized focus breathing and focus/axial shift while zooming
  • Advanced operability and balance for prolonged professional use

Ultra-wide 20 mm to mid-tele 70 mm zoom range, for a wide range of movie and still subjects.

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.    

Outstanding G Lens image quality with corner-to corner high resolution at all focal lengths

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.    

Peak AF performance with two XD Linear Motors for precise, fast, quiet focus drive

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 tracking2. Moving subjects are reliably tracked when shooting continuous stills at up to 30 fps3, or up to 4K 120p with alpha compatible cameras.    

Refined movie imagery with minimized focus breathing and focus/axial shift while zooming

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.    

Compact, lightweight design for superb image quality and versatility in any situation

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.    

Excellent close-up performance of 9.8” (25cm) throughout the zoom range (manual focus)

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.

Constant F4 maximum aperture throughout zoom range for greater flexibility

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.    

Circular aperture with 9-blade iris for naturally rendered bokeh

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 supports ultra-wide images

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.    

Dedicated aperture ring, click/de-click and iris lock switches

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    

Customizable focus hold buttons

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.

ED glass elements correct spherical and chromatic aberrations

Three ED (Extra-low Dispersion) glass elements plus one ED aspherical glass element significantly reduce chromatic aberration for sharp reproduction without color bleeding. 

Natural, linear manual focus response

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.    

Instant auto/manual focus selection

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.    

Fluorine front element coating

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.     

Dust and moisture resistant design for reliability in challenging conditions

An updated dust and moisture resistant design 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.    

Front 72mm threaded for screw-on filters

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.    

Petal-shaped, bayonet mount lens hood

Petal shaped, bayonet mount lens hood ALC-SH174 is supplied, and also available separately as an optional accessory.
