Key Features
Wide ratio (6.1x) power zoom lens
This advanced powered zoom lens has been designed for optimum performance in prostandard Super 35mm / APS-C moviemaking applications. Starting at 18mm wide-angle and
extending through an impressive 6.1x zoom range, it oers a constant F4 maximum aperture all
the way. Controls and layout have also been optimized for moviemaking.
High-quality G-Lens™ optical design - ideal for 4K moviemaking
High-quality G Lens optical performance delivers image quality that will satisfy the most
demanding professional requirements. Six aspherical elements and three ED glass elements in an
18-element 15-group design eectively suppress spherical and chromatic aberration throughout
the zoom range, from the image center to periphery, achieving high resolution that is ideal for
4K production. This lens is not only an excellent choice for movies, but oers outstanding image
quality for still photography as well, with stunning resolution throughout every APS-C format
image.
Smooth Motion Optics
SMO (Smooth Motion Optics) design and construction minimizes unwanted focus and image
shis while focusing or zooming for stable, high-level 4K movie production while ensuring smooth,
quiet operation. Unwanted image shis that can have a signicant impact on movie quality.
Focus “breathing” or shis in angle of view during focusing are minimized by an internal focus
mechanism. Small focus shis that can occur while zooming are eliminated by precise focus
tracking adjustment and axial image shis while zooming are minimized by a constant-length
design.
Constant F4 max aperture and 7-blade circular iris
Constant F4 max aperture maintains exposure and depth of eld regardless of the focal range
you chose to zoom to. When changing your aperture to defocus the background, the areas
outside of the focal plane appear blurred. This ‘bokeh’ eect of the blurred background can be
enhanced with circular aperture blades used in this lens. Conventional aperture blades have at
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 wideopen setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained
as a result
Servo / manual mechanical zoom w/ switchable zoom ring direction
High-level zoom functions include responsive manual zoom in addition to servo zoom for precise
and exible control in any situation. A mechanical drive system for manual zoom operation
ensures direct, responsive control with no lag. The desired angle of view can be easily and
accurately reached without overshoot or undershoot. When servo zoom is required it can be
quickly activated by a switch. The direction of the zoom ring can also be switched to match
individual user preferences. Slow zoom is also supported, up to three times slower than the FE PZ
28-135mm F4 G OSS.
Independent Zoom, Focus and Iris rings for superior control
Independent focus, zoom and iris (aperture) rings oer superior direct operability and reliability
for professional visual production. The focus ring slides to switch between auto and manual focus
(AF/MF), so the switchover can be made with no break or change in shooting posture. It also
includes a distance scale to aid manual focus and a 0.8mm pitch focus gear, built right onto
the focus ring, which provides direct compatibility with standard focusing accessories. Servo /
manual mechanical zoom with switchable zoom ring direction oer precise control over a wide
range of shooting conditions. The iris ring can be switched between clickable aperture stops for
still image or o for smooth and silent iris control for video.
Inner focus and zoom
Internal focus and zooming means the overall length of the lens remains constant. This makes it
easy to use matte boxes and other lens accessories, and also minimizes center of gravity shi so
that the lens remains ideally balanced for stable shooting. The lter thread at the front of the lens
does not rotate, which is convenient if you’re using a polarizing lter.
Dust and moisture resistant design for maximum
The dust and moisture resistance design makes this lens appropriate for heavy-duty outdoor use,
especially when combined with a camera that employs weather resistant measures such as the
Sony’s a7 series of cameras1. Design and manufacture are carried out to rigorous standards,
ensuring the highest possible performance and reliability for movie production.

Super Sonic wave motor drive for zoom with internal zoom structure
This power zoom lens oer enhanced control and expressive potential for moviemaking, with
smooth, consistent zooming that is dicult to achieve manually. Details like smooth acceleration
and deceleration are important too, and of course tracking is excellent throughout. The SSM
(Super Sonic wave Motor) drive is ideal for moviemaking as it achieves quiet zoom and extrasmooth iris control.
Silent Iris and linear AF drive system for quiet operation
Noise while adjusting iris or focus can be an unwanted distraction on your movie soundtrack.
Sony's advanced iris control and linear AF motor drive system achieve quiet focusing that is also
extremely responsive. Part of the reason that focus control is so quiet is that original Sony linear
motors are contactless, with no gears or mechanical coupling to generate noise
Optical SteadyShot™ image stabilization for video and stills
Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens
is precisely shied to counteract any image blur that might occur. The use of precision, quiet
linear motors and technology inherited from high-end Sony professional camcorders results in
exceptionally quiet, eective image stabilization that contributes to high-quality movies as well as
stills.
ED glass / Super ED glass
As focal lengths get longer, lenses built with conventional optical glass have diculties with
chromatic aberration, and as a result images suer from lower contrast, lower color quality, and
lower resolution. ED (Extra-low Dispersion) glass dramatically reduces chromatic aberration at
telephoto ranges, and provides superior contrast across the entire image, even at large aperture
settings. Super ED glass provides enhanced compensation for chromatic aberration.
Aspherical lens elements
Aspherical lens design dramatically reduces spherical aberration while also reducing lens size
and weight. Spherical aberration is a slight misalignment of the light rays projected on the image
plane. This is caused by dierences in refraction at dierent points on conventional spherical
lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical”
elements near the diaphragm restore alignment of light rays at the image plane, maintaining
high sharpness and contrast even at maximum aperture and can also be used at other points in
the optical path to reduce distortion. Well-designed aspherical elements can reduce the total
number of elements required in the lens, thus reducing overall size and weight
