A fast, standard zoom favored for
its versatility, the Sony FE 24-70mm f/2.8 GM is a wide-angle
to short telephoto lens designed for E-mount mirrorless cameras. Featuring a
constant f/2.8 maximum aperture, this lens maintains consistent performance
throughout the zoom range and benefits working in low-light conditions and with
selective focus techniques. Complementing the apt light-gathering capabilities
is an equally impressive optical design, which incorporates three aspherical
elements and two extra-low dispersion elements. One of the aspherical elements
features an XA (extreme aspherical) designation, ensuring its refined surface
precision and notable ability to minimize spherical aberrations throughout the
zoom range. Additionally, a Nano AR Coating has been applied to individual
elements to significantly minimize lens flare and ghosting for increased
contrast and color neutrality. Pairing a sophisticated optical design and
versatile speed, this standard zoom is well-suited for use in a wide array of
environments and lighting conditions.
Beyond the attributes of the lens system itself, this
24-70mm is also characterized by a Direct Drive SSM (Super Sonic wave Motor)
system that provides fast, quiet AF performance as well as responsive manual
focus handling. The lens is also dust- and moisture-sealed, to permit working
in inclement weather conditions, and nuanced details, such as a focus hold
button and rubberized control dials, further the intuitiveness in handling.
As part of Sony's esteemed G Master
series, this lens is designed to achieve notably high resolution and sharpness
through the correction of a wide variety of spherical and chromatic
aberrations. Additionally, these lenses feature robust and intuitive-to-handle
physical designs to benefit both photography and cine applications.
Covering wide-angle to
portrait-length perspectives, this standard 24-70mm zoom is designed for
full-frame E-mount mirrorless cameras and is also compatible with APS-C models,
where it will provide a 36-105mm equivalent focal length range.
Constant f/2.8 maximum aperture
maintains consistent performance from wide-angle to telephoto focal length
positions and also contributes to greater selective focus control.
Of the three aspherical elements
incorporated in the lens design, one is an XA element with superior surface
precision to effectively reduce astigmatism, field curvature, coma, and other
monochromatic aberrations from imagery.
One extra-low dispersion element
and one Super ED element are featured in the lens design and help to control
chromatic aberrations and reduce color fringing for increased clarity and color
fidelity.
A Nano AR Coating has been applied
to reduce surface reflections, flare, and ghosting for increased contrast and
color rendering in strong lighting conditions.
A Direct Drive Super Sonic wave AF
motor and internal focus mechanism provide quick, quiet, and precise autofocus
performance and also contribute to more natural, intuitive manual focus
control.
A focus hold button and AF/MF
switch are present on the lens barrel for intuitive tactile control and rapid
access to select settings.
A dust- and moisture-sealed design
better permits working in inclement conditions and rubberized control rings
benefit handling in colder temperatures.
Rounded nine-blade diaphragm
contributes to a pleasing bokeh quality when employing selective focus
techniques.
