Product Description
Compact, lightweight standard zoom covers ultra-wide 20 mm to 70 mm
Redefines the standard zoom lens category with a focal length range that extends
from ultra-wide 20 mm to 70 mm in a remarkably compact, lightweight full-frame
lens with constant F4 maximum aperture.
From ultra-wide 20 mm to 70 mm
With an unprecedented 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 0.98 feet (wide) to 0.82 feet (telephoto) when using AF, and 0.82 feet
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.
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.
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 speed and up to two times2 better performance
while tracking for reliable, precise tracking. Moving subjects are reliably
tracked when shooting continuous stills at up to 30fps, and high-frame-rate
movie capture is smooth.
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 α
series bodies is also supported.
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.
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.
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 design
A dust- and moisture-resistant design 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.
