Sony Full-Frame E-Mount 28-135mm Power Zoom Lens - SELP28135G

Product Details
Sony Full-Frame E-Mount Power Zoom Lens - SELP28135G
Dare to be different with this Sony 28-135mm f/4 power zoom E-mount lens. It's the perfect video lens thanks to its powered zoom, which ensures you can focus in on your subjects quickly and efficiently with constant motion. This works with the ultra-quiet focusing and zooming motor that ensures you maintain absolute sharpness without hearing any grinding on the audio soundtrack. This Sony powered zoom lens also has manual focusing and zooming options for easy control of the starting point when filming wildlife, sports or weddings. A constant f/4 aperture keeps lighting consistent throughout the shot, even when used with a Sony Handycam or a Super 35 format camcorder.
When you want to use this telephoto zoom lens for stills, it performed just as effectively. Sony SteadyShot optical stabilization keeps your photos looking crisp and sharp even when the light levels fall, and a circular aperture ensures bokeh looks creamy when shooting fully open. Dust and moisture resistance from this Sony 28-135mm f/4 power zoom E-mount lens ensure photos look good without moisture or dust creating blurs, smudges or dust bunnies.
Features
Precision G-series optical design for HD and 4K moviemaking
The SELP28135G is a powered zoom lens that has been created to satisfy professional
optical and operational requirements for both high-quality still and movie
imagery, including 4K, when matched with a full-frame format camera such as
the a7S or a Super 35 format camcorder such as the PXW-FS7
No “Breathing”
When making movies you’re 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 SELP28135G features
an optical design and control technology inherited from Sony’s professional
camcorders that ensure no breathing
No focus shifting or axial displacement while zooming
Zooming is a fundamental moviemaking technique that is used for both practical
framing changes as well as creative effect. “Smooth” is the key
requirement for video. Any tracking irregularities such as jitter or axial
image shifts are unacceptable. The SELP28135G delivers exceptionally smooth
tracking throughout the zoom range at any speed and eliminates any axial image
shifting. Zooming is quiet as well as responsive thanks to advanced mechanical
actuator design
Independent Zoom, Focus and Iris rings for superior control
Independent control rings for zoom, focus, and iris (aperture) are provided
for the first time in an a lens. The focus mode can be switched from auto
to manual simply by sliding the focus ring forward so control is maintained
at all times. Zoom speed can be precisely controlled over a wide range, with
zoom rotation direction reversal capability. All three control rings have
been engineered to provide ideal torque for comfortable, responsive operation.
Even the pitch of the scalloping on the rings has been painstakingly designed
for comfortable, slip-free control
Constant F4 Circular Aperture
Constant F4 max aperture maintains exposure and depth of field regardless
of the focal range you chose to zoom to. When changing your aperture to defocus
the background, the areas out of the focal plane 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. a 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
Super Sonic wave motor drive for zoom with internal zoom structure
This power zoom lens offer enhanced control and expressive potential for moviemaking,
with smooth, consistent zooming that is difficult to achieve manually. Details
like smooth acceleration and deceleration are important too, and of course
tracking is excellent throughout. The SELP28135G features the world’s
first SSM (Super Sonic wave Motor) drive in a lens designed for moviemaking
to achieve quiet zoom and extra-smooth iris control
Quiet Iris and auto focus
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
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 cameras
Lens-based Optical SteadyShot® image stabilization
Gyro sensors built into the lens detect even the slightest movement, and the
stabilization lens is precisely shifted 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,
effective image stabilization that contributes to high-quality movies as well
as stills
Internal focusing
The middle AF group of the optical system is smaller, lighter, and easier
to move rapidly to achieve focus,. So 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 you’re using a polarizing filter
Nano AR Coating
Effectively suppress reflections that can cause flare and ghosting with Sony’s
original Nano AR Coating technology. This precisely defined regular nano-structure
allows accurate light transmission, contributing to high-quality images, even
more so than lenses with coatings that use 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
ED (Extra-low Dispersion) glass / Super ED glass
As focal lengths get longer, lenses built with conventional optical glass
have difficulties with chromatic aberration, and as a result images suffer
from lower contrast, lower color quality, and lower resolution. ED 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 differences
in refraction at different 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
