Product Description
SEL70200GM 70-200mm F2.8 fixed zoom G Master lens
An incomparable constant aperture F2.8 70-200 mm telephoto zoom with
extraordinary G Master resolution that offers unsurpassed rendering and bokeh,
blazing AF, and extraordinary image stabilization performance
Extraordinary detail and bokeh in one lens
G Master design combines extraordinary sharpness and smooth Bokeh in one
lens. It is not easy to achieve spatial frequency of 50 lines pairs per
millimeter at a lens's widest aperture and produce smooth beautiful bokeh at the
same time, but that is Sony's baseline for G Master design. Unprecedented
resolution and other demanding design parameters yield outstanding reproduction
of the most detailed subjects and scenes with superior contrast throughout every
frame. G Master resolution is simply the highest in its class.
11-blade circular aperture for luscious bokeh
When changing your aperture to defocus the background, the light sources
appear blurred. This bokeh effect of the blurred background can be enhanced
with circular aperture blades used in this lens. Conventional aperture blades
have flat sides creating unappealing, polygonal shaped defocussed points of
light. α lenses overcome this problem through a unique design that keeps the
aperture almost perfectly circular from its wide-open setting to when it is
closed by 2 stops. Smoother, more natural defocusing can be obtained as a
result.
Class-leading close-up performance
Class-leading close-up performance with a minimum focusing distance of 37.8
and 0.25x maximum magnification is ideal for portraits, telephoto macro, and
more. Contributing refinements include ED glass elements and a floating focus
mechanism to control aberration that can be problematic in close-up
applications.
Dust and moisture resistant for robust reliability
Sonys standard lens sealing is augmented by a lens mount seal that
maximizes resistance to dust and moisture for reliable operation in challenging
environmental conditions. Additional details like rubberized rings that are easy
to operate in low temperatures, a zoom lock that prevents unwanted lens
extension during transport, and a hood lock button, all add up to professional
control and convenience.
No Breathing
When making movies youre frequently focusing while shooting, either with
autofocus or manual focus. A lens that has not been designed with movies in mind
might exhibit breathing, or variations in the angle of view while focusing
which can be a jarring distraction. The SEL70200GM features an optical design
and control technology inherited from Sonys professional camcorders that ensure
minimal focus breathing.
Fast AF optimized for stills and video
Two heavy focus groups are rapidly and precisely positioned by separate
actuators: a powerful ring SSM (Super Sonic wave Motor) actuator for the front
group, and a double linear motor actuator for the rear group. Improved
positioning precision works with real-time feedback from multiple position
sensors to allow the bodys AF system to operate at full capacity.
Parfocal design ideal for video
Zooming is a fundamental moviemaking technique that is used for both
practical framing changes as well as creative effect. Parfocal means the
SEL70200GM holds focus on a subject even when zooming in or out.
High performance Optical SteadyShot Image stabilization
High-performance image stabilization is built right into the lens for sharp,
blur-free images with a wide range of subjects. The heavy stabilization lens is
driven by a linear motor for fast, precise stabilization. 5-axis image
stabilization becomes available when used with α series bodies that feature
built-in image stabilization. To provide the greatest possible benefit from the
built-in image stabilization system in the widest range of shooting situations,
the features switchable MODE 2 stabilization allows image stabilization to be
used with panned shots for greater clarity and impact.
Constant lens length during focusing and zooming
With the new design of the SEL70200GM, the overall length of the lens does
not change and the lens is able to achieve shorter minimum focusing distance.
The filter thread at the front of the lens does not rotate, which is convenient
if youre using a polarizing filter
ED and Super ED glass reduces flare and ghosting
ED (Extra-low Dispersion) and Super ED glass elements take axial chromatic
aberration and chromatic aberration due to differences in magnification out of
the picture, maximizing resolution and bokeh while leaving precisely rendered
edges with no fringing or unnatural coloration.
Outstanding clarity and contrast
Sonys original Nano AR Coating technology minimizes flare and ghosting, for
dynamic range that achieves lifelike detail and gradation with advanced camera
sensors. This precisely defined regular nano-structure allows accurate light
transmission, contributing to high-quality images, even more so than with lenses
that use coatings with an irregular nano-structure. The reflection suppression
characteristic of the Nano AR Coating is superior to conventional
anti-reflective coatings, providing a notable improvement in clarity, contrast,
and overall image quality.
