Features
Uncompromising G Master design
In order to take full advantage of the potential of high-resolution sensors, G Master is designed from the
outset for high contrast at the highest possible spatial frequency, thereby achieving outstanding corner-
to-corner optical resolution and clarity at all zoom and focus settings. It is not easy to achieve spatial
frequency of 50 line pairs per millimeter at a lens's widest aperture, but that is Sony's baseline for G
Master design, combining smooth bokeh and high resolution for outstanding reproduction of the most
detailed subjects and scenes, with superior contrast throughout every frame. G Master realizes the rare
combination of high resolving power and beautifully rendered background defocus.
Previously unattainable surface precision
Two XA (extreme aspherical) elements with extremely high surface precision (better that 0.01-micron)
are included and work with three aspherical elements to minimize aberrations that commonly plague
wide-angle zooms, effectively controlling distortion, field curvature and astigmatism. The extremely
precise XA elements reduce aberration and deliver ultimate corner-to-corner resolution throughout the
entire zoom and aperture range.
Constant F2.8 max aperture
Constant F2.8 max aperture maintains exposure and depth of field regardless of the focal range to which
you zoom. When changing your aperture to defocus the background, the areas out of the focal plane
FE 16-35mm F2.8 GM Wide-angle Zoom Lens
SEL1635GM
Explore the world in creative new ways with exceptional G Master
performance in a 16-35mm F2.8 wide-angle zoom. This lens delivers
consistently superb resolution from corner-to-corner, no matter what zoom
setting or focus distance at which you shoot. It produces stunning background
bokeh that can add depth and artistic impact to your images when required. A
compact, lightweight design makes the FE 16-35mm F2.8 GM a great choice for
active shooting.
appear blurred. This ‘bokeh’ effect of the blurred background is enhanced with circular aperture blades
used in this lens.
11-blade circular aperture contributes to gorgeous bokeh
When changing your aperture to defocus the background, light sources appear blurred. This ‘bokeh’ effect
of the blurred background is enhanced with the 11-blade circular aperture used in this lens. Conventional
aperture blades have flat sides creating unappealing, polygonal-shaped defocused points of light. α lenses
overcome this problem through a 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.
Two Direct Drive Supersonic Wave Motor (DDSSM)
High-resolution cameras demand absolute focus precision. A floating mechanism driven by two DDSSM
(Direct Drive Super Sonic Wave Motor) actuators maintains outstanding resolution from infinity to close
focus for both stills and movies. DDSSM has the capability to position the large, heavy optical assemblies
required by large-aperture lenses with pinpoint precision, offering accurate, fast and quiet autofocus.
Manual focus response is natural and intuitive with the DDSSM system.
Nano AR Coating
Sony’s original Nano AR Coating technology minimizes flare and ghosting by suppressing internal
reflections and maintaining clarity, even in difficult outdoor lighting conditions, 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, 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.
Dust and moisture resistant1 for robust reliability
Sony’s standard lens sealing is augmented by a lens mount seal that maximizes resistance to dust and
moisture for reliable operation in challenging environmental conditions1. Additional details, like
rubberized rings that are easy to operate in low temperatures, a customizable focus hold button and a
hood lock button, all add up to professional control and convenience.
ED glass minimizes chromatic aberration
Two ED (Extra-low Dispersion) 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 minimal fringing or unnatural coloration.
Instant auto/manual focus selection
Instantly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes
operation faster and easier as you let the camera and lens focus for you, or decide to take control and
manually focus on the precise point you chose.
Focus hold button
The focus hold button not only performs its primary function to lock focus when recomposing, but can be
customized to a number of other functions depending on your needs. In addition to Focus Hold, custom
functions include: Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.
Internal Focus maintains lens dimensions
Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does
not change while focusing. This is especially useful when using the lens for video with a matte box. In
addition, the filter thread at the front of the lens does not rotate, which is convenient if you’re using a
polarizing filter.
Fluorine front-element coating
The front lens element features a fluorine coating that helps to prevent dirt and fingerprints from
sticking, and makes it easier to wipe dirt and fingerprints away if they become attached to the lens
surface. This is a lens that can be used with confidence in a variety of challenging outdoor conditions.
