Sony FE 70-200mm f/2.8 GM OSS II Lens
Sony 70-200mm f/2.8 GM OSS II Overview
Building on the success of its predecessor, the FE 70-200mm f/2.8 GM OSS II Lens from Sony is an evolved and improved telephoto zoom lens for professionals. It is lighter than its predecessor but boasts performance improvements in every area of operation. This addition to the G Master series delivers increase sharpness with a minimum of aberrations with an optical design that includes an XA element, an aspherical element, two extra-low dispersion aspherical elements, two extra-low dispersion elements, and two Super ED elements. This optical design aslo features Sony's latest generation Nano AR II Coating that reduces reflections, flare, and ghosting for improved contrast and color.
Four XL Linear motors make autofocus fast, precise,
and highly responsive for stationary subjects and for tracking, with two motors
driving each of the internal focusing groups. The floating focus design divides
the elements into two independently controlled groups for increased
responsiveness, for both still and video applications, with speeds up to four
times faster than its previous version design. The FE 70-200mm f/2.8 GM OSS II
lens is the first large-aperture tele-zoom lens with four linear AF actuators,
which work to reduce focus breathing and focus shift while zooming. Direct
manual focus is available full-time, and linear response manual focus function
changes the manual focus response based on the focus ring rotations speed.
For durability and working in harsh environments, the
lens is dust and moisture resistant, and the front element features a fluorine
coating to resist water and oil. The lens features a removable rotating tripod
collar and a lens hood that provides access to rotate a separately available
accessory polarizing filter.
As part of Sony's flagship 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.
A popular 70-200mm telephoto zoom range designed for
full-frame E-mount mirrorless cameras, this lens is also compatible with APS-C
format cameras where it renders a 105-300mm equivalent focal length range.
The constant f/2.8 maximum aperture offers consistent
performance throughout the zoom range and lends greater control over focus
position for shallow depth of field techniques.
Two extra-low dispersion elements and two Super ED
elements reduce chromatic aberrations and color fringing for increased clarity
and color fidelity. Each optical surface has a Nano AR Coating II applied to
reduce surface reflections, flare, and ghosting for increased contrast and
color rendering in strong lighting conditions.
Four XD (extreme dynamic) Linear Motors ensure fast,
precise, and accurate autofocus in both stills and video, with increased speed
and improved tracking over the previous model, and reduced focus breathing,
zoom shifting, and axis shifting for refined cine shooting.
Optical Steady Shot image stabilization helps to
minimize the appearance of camera shake for sharper imagery when shooting
handheld with slower shutter speeds. This stabilization system can also be
combined with select camera's sensor-shift type image stabilization for more
effective control of camera blur. An OSS mode switch lets you choose Mode 1 for
general image stabilization that is suited to most types of shooting, a Mode 2
setting that is designed for panning movements, and Mode 3 for emphasizing framing
stability when shooting moving subjects.
The lens barrel is equipped with three programmable
focus control buttons and a focus range limiter switch to permit fast,
intuitive operation of the lens while shooting.
The front lens element features a fluorine coating to
protect against smudges and dust from adhering to the glass surface. Dust- and
moisture-sealed design better permits working in harsh environments.
A removable, rotating tripod mount permits quick
switching from horizontal to vertical shooting orientations.
Included lens hood features a flocked interior for
reduce glare and an opening that allows convenient operation of separately
purchased circular polarizing or other rotating filters.
Compatible with Sony's optional 1.4x and 2x
teleconverters, this lens can be easily transformed into a 98-280mm or
140-400mm optic, respectively.
