Sony Sony Fe-Mount>FE 20-70mm f/4 G Lens

Compact, Lightweight Standard Zoom Covers Ultra-Wide 20mm to 70mm

The Sony FE 20-70mm f/4 G Lens redefines the standard zoom category with a focal length range that extends from ultra-wide 20mm to 70mm in a remarkably compact, lightweight full-frame lens. Maximum aperture is a constant F4.

With an unprecedented ultra-wide 20mm to short-telephoto 70mm zoom range, this versatile lens is an excellent choice for a wide variety of movie and still subjects, from expansive landscapes to intimate portraits. The ultra-wide 20mm end of the zoom range makes it possible to maintain a wide angle of view even when shooting movies with a 16:9 or 2.35:1 aspect ratio that would normally reduce view angle.

F4 Maximum Aperture Throughout the Zoom Range.

A constant F4 maximum aperture provides extra versatility for choosing an aperture that best suits the user’s intent at any focal length from 20mm to 70mm. 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.

Compact, Lightweight Design for Maximum Mobility

The Sony FE 20-70mm f/4 G Lens offers an extended 20mm through 70mm standard zoom range with outstanding optical performance in a remarkably compact, lightweight lens thanks to Sony’s latest lens design and XD (extreme dynamic) Linear Motor technology.

Combined with a compact mirrorless body this lens can deliver superb image quality in just about any situation, at focal lengths from ultra-wide to short-telephoto. It is an excellent choice for shooting with a minimum amount of gear, or in cases where a number of prime lenses might normally be required.

Outstanding Image Quality Consistent with the G Lens Logo

The Sony FE 20-70mm f/4 G Lens delivers stunning image quality and gorgeous bokeh that are fully in keeping with the G Lens logo. The latest lens design technology makes inimitable G Lens image quality available in a surprisingly compact, lightweight lens. With two AA (advanced aspherical) elements, one aspherical element, three ED (Extra-low Dispersion) glass elements, and one ED aspherical element, this lens’s state-of-the-art optical design simultaneously corrects chromatic and spherical aberration for extremely high optical performance right out to the image edges, from the ultra-wide 20mm end of the zoom range to 70 mm. Optimised coatings add high flare and ghost resistance to this superior optical design, for extraordinary contrast and clarity.

Beautiful 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.

Excellent Close-up Performance

Excellent close-up performance at all focal lengths is achieved thanks to an innovative optical design that incorporates Sony’s high-precision AA (advanced aspherical) elements. Minimum focusing distance is 0.3 metres at the wide end and 0.25 metres at the telephoto end of the zoom range when using AF, and 0.25 throughout the zoom range when focusing manually. Maximum magnification is 0.39x for dynamic, detailed close-ups. A short minimum focusing distance makes it easy to manoeuvre around subjects such as small flowers to find the ideal angle.

Maximises Camera AF Performance for Stills and Movies

The lens’s focus group is driven by two of Sony’s latest XD (extreme dynamic) Linear Motors, providing high thrust for fast, quiet, low-vibration focus drive. Thrust efficiency has been significantly improved over previous models , resulting in approximately a 60% increase in AF speed . And because tracking performance has been improved by about 2 times compared to the previous model , moving subjects are tracked with consistent reliability and precision. Reliable tracking is achieved when shooting continuous stills of fast-moving subjects at up to 30 frames per second with the α1 body, and subjects can be smoothly recorded when shooting movies at a high frame rate.

Movie Performance Designed for Refined 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 carefully designed for quiet operation when shooting movies, with advanced XD linear motors and a newly developed aperture unit that dramatically reduces noise and vibration.

Active Mode Image Stabilisation Support for Ultra-Wide Images and Movies

α series camera Active Mode image stabilisation is highly effective at the ultra-wide 20 mm end of the Sony FE 20-70mm f/4 G Lens zoom range, providing excellent image stabilisation performance while maintaining a wide angle of view. This can be particularly useful for shooting smooth, stable handheld footage while walking.

Smooth, Quiet, High-Performance AF for Movies

Focus is especially critical when shooting high-resolution 4K or 8K movies. The Sony FE 20-70mm f/4 G Lens (SEL2070G) works with α series camera bodies to easily acquire accurate focus and smoothly track fast-moving subjects thanks to two high-thrust XD Linear Motors and a high-level control system in a compact, lightweight lens. The ability to leave focusing to the camera when shooting solo can be a huge advantage.

Linear Response MF Support

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.

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.

Comprehensive Control in a Compact Lens.

Independent focus, zoom, and aperture rings feature optimised diameter, width, and positioning for full control when shooting stills as well as maximum versatility when recording movies. The adjacent zoom and aperture rings are stepped for error-free tactile control while watching the monitor.

Customizable Focus Hold Button

Customizable focus hold buttons are provided in two locations for easy access and convenient control. Other functions can be assigned to the focus hold button from the body menus to match shooting needs.

Focus Switch for Instant AF/MF Switching

A focus mode switch on the side of the lens makes it possible to switch between autofocus and manual focus on the fly, to quickly adapt to changing shooting conditions.

Comprehensive Control in a Compact Lens

An Iris Lock switch provides the following settings:

Lock ON:

The aperture ring is either fixed at the “A” position to prevent unwanted changes while shooting, or it can be manually set between F4 and F22.

Lock OFF:

The aperture ring can be seamlessly moved between “A” and F4.

Threaded for screw-on filters The SEL2070G accepts standard 72mm screw-on filters for expanded creative freedom. Thanks to its internal focus system the filter ring does not rotate while focusing, facilitating the use of circular polarising filters for landscape photography or variable ND filters for movies.

Reliable in Any Environment

A dust and moisture resistant design provides extra reliability for outdoor use in challenging conditions. 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.
