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.
