Sony SEL 20-70mm f/4.0 G Sony FE mount

The new SEL2070G full-frame lens from Sony:
A new ultra-wide-angle standard zoom lens from the Premium G series with a constant F4 aperture offers optimized image quality and excellent operability specifically for full-frame photos and videos.

The advanced optical design incorporates four ED (Extra Low Dispersion, one of which is aspherical), two AA (Advanced Aspherical) elements and one normal aspherical element to ensure outstanding resolution.

For particularly soft background blur (bokeh), the 9-blade circular aperture is used.

Two complex XD (Extreme Dynamic) linear motors enable faster and more accurate focusing when shooting video and stills.

Sony's SEL2070 G Lens is especially optimized for video.
It offers smooth, fast and accurate autofocus performance even when shooting video, and boasts minimized focus breathing as well as focus shift and axis shift when zooming.

UNBELIEVABLY SHARP:
Four ED (Extra Low Dispersion, one of which is aspherical), two AA (Advanced Aspherical) elements, and one normal aspherical element ensure outstanding resolution all the way to the edge of the frame, and beautiful bokeh makes this outstanding full-frame lens ideal for content creation, photo and video shooting.

WONDERFULLY SOFT BACKGROUND:
Thanks to a 9-blade circular aperture, this 20-70mm G Lens from Sony creates beautiful bokeh effects with background blur at a constant F4 aperture.

FASTER AND MORE ACCURATE AUTOFOCUS:
Two complex XD (Extreme Dynamic) linear motors enable faster and more accurate focusing when shooting video and stills. You'll never miss a shot with this ultra-wide-angle lens including standard zoom.

BRIGHTNESS REGARDLESS OF WEATHER:
A constant maximum F4 aperture throughout the zoom range ensures consistent brightness even as the focal length changes. The front element of this Sony G Lens features a fluorine coating that repels water, oil and other contaminants. This makes it easy to wipe away dust and fingerprints.

PROFESSIONAL ERGONOMICS:
A dust- and water-resistant design and versatile controls make this Sony G Lens the ideal companion for even the most demanding situations - indoor and outdoor. Plus, this ultra-wide-angle standard zoom lens is compatible with Focus Breathing Compensation.

FUTURE-ORGANIZED:
Sony lenses also let you make the most of the features of your next Sony camera.

Compact, lightweight standard zoom extremely wide from 20mm to 70mm:
With a ^unique2, extremely wide zoom range of 20mm to 70mm for telephoto, this versatile lens is a great choice for a wide range of movie and continuous shooting. The ultra-wide 20mm zoom range maintains wide angle of view when shooting movies with 16:9 or 2.35:1 aspect ratios that reduce the angle of view.

Standard Sony zoom lens redefined: ultra-wide 20mm to 70mm
These versatile, high-performance E-mount lenses offer a zoom range of ultra-wide 20mm to 70mm in a compact, lightweight model carefully engineered for uncompromising image quality, AF performance and movie usability.

Outstanding Image Quality with G Lens from Sony
With two AA (Advanced Aspherical) elements, one aspherical element, three ED (Extra-low Dispersion) glass elements, and one ED aspherical element, these state-of-the-art Lenses simultaneously correct chromatic and spherical aberration for extreme optical performance to the image limits of ultra-wide 20mm to 70mm.

Unparalleled AF performance for stills and video
Two powerful XD (Extreme Dynamic) linear motors bring fast, quiet, stepless autofocus. Improved thrust efficiency1 delivers up to 60% faster ^AF2 and tracking performance has been ^doubled in places2, tracking is reliable and precise. Motion images are reliably tracked at up to 30 ^fps3 during continuous shooting, and movies are smoothly recorded at high frame rates.

Refined Video Shooting
Advanced lens technology reduces breath compensation and axis shifts during zooming, reducing distracting frame changes. XD linear motors and the newly developed aperture unit dramatically reduce noise and vibration during movie recording. Breathing Compensation in compatible α series housings5 is also supported.

High user-friendliness and reliability everywhere
The Lens is dust- and moisture-resistant with a flour-coated, contaminant-repellent front element. All controls, such as customizable focus hold buttons and independent rings for focus, zoom and iris, provide smooth, versatile control in stills and movies. A focus mode switch simplifies switching between autofocus and manual focus.

Excellent Close-up
AA (Advanced Aspherical) elements provide a minimum focus distance of 0.3 meters (wide) to 0.25 meters (telephoto) for AF, and 0.25 meters throughout the zoom range for manual zoom. A maximum magnification of 0.39x ensures detailed close-ups. Close focus lets you walk around small subjects to find the ideal angle.

Constant Maximum F4 Aperture
The maximum constant aperture of F4 provides great flexibility in aperture selection at any focal length. The selected aperture remains constant throughout the zoom range. Extreme ISO settings at telephoto are unnecessary, and high shutter speeds can be used as needed for the desired effect.

Unparalleled AF performance for stills and video
Dual XD (Extreme Dynamic) linear motors provide fast, smooth, and jerk-free focus with up to 60% faster AF3 and up to ^twice3 as good tracking ^performance3 for reliable, accurate tracking. Motion images are reliably tracked at up to 30 ^fps4 during continuous shooting, and movies are smoothly captured at high frame rates.

Compact, Lightweight, Mobile Design
This compact, lightweight Lens combines state-of-the-art optical design with high-thrust XD (Extreme Dynamic) linear motor technology. Built into a compact body, it delivers first-class image quality in all situations at focal lengths from extreme wide to short telephoto. A great choice for shooting with little equipment.

Active Mode6 supports extremely wide images
Active Mode6 image stabilization in the α series cameras works great at the extremely wide end of the zoom range (20mm), providing excellent image stabilization while maintaining a wide angle of view. This is especially important when shooting smooth, stable handheld shots while walking.

Aperture ring with on/off click switch
An independentaperture ring provides direct, intuitive aperture control. The on/off click switch can be turned off when smooth, stepless operation is needed.

Dust and splash resistant ^design7
Dust and splash resistant ^design7 provides the reliability needed in challenging outdoor conditions.

Fluorine coating on front element
The front lens element features a fluorine coating that protects against fingerprints, dust, water, oil, and other contaminants, while making it easy to wipe off if dirt does stick to the surface.

Focus hold button and focus adjustment switch
Customizable focus hold buttons provide easy access and control in two locations. Other functions can be assigned to the focus hold button via menu settings to meet the challenges of all shooting situations. A focus adjustment switch lets you spontaneously switch between autofocus and manual focus to quickly adapt to changing shooting situations.
