Sony SEL85F14GM Specifications
SEL85F14GM
Full-frame G Master telephoto prime lens
Portrait performance reaches a new pinnacle with
astonishing resolution plus bokeh of unmatched beauty.
This 85mm F1.4 portrait lens renders infocus areas with
unequalled resolution while the background dissolves
into the smoothest, lushest bokeh imaginable. All of
this is by design, supported by manufacturing and
testing technology that only Sony can provide, for new
dimensions of photographic and cinematographic
expression.
Key Features
Designed to achieve 50 line pairs/mm resolving power
It is not easy to achieve spatial frequency of 50 lines pairs per millimeter at a lens's widest
aperture, 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.
Previously unattainable surface precision
Built with three aspherical elements including a newly developed and essential ingredient for
astonishing resolution - is a new XA (extreme aspherical) lens element with better that 0.01-micron
surface precision. The extremely precise XA element reduces aberration and delivers the ultimate
resolution throughout the entire zoom range and aperture range, as well as from corner to corner
of all image les.
Constant F1.4 max aperture maintains exposure and depth of eld
Constant F1.4 max aperture maintains exposure and depth of eld regardless of the focal range
you choose to zoom to. When changing your aperture to defocus the background, the areas
out of the focal plane appear blurred. This ‘bokeh’ eect of the blurred background can be
enhanced with circular aperture blades used in this lens.
11-blade circular aperture contributes to gorgeous bokeh
Complementing the performance of the XA element are the rst 11-blade circular aperture ever
implemented in an α lens, and exacting spherical aberration adjustment for each individual lens.
The result is enchantingly so-edged bokeh that is a hallmark of the Sony G Master series.
When changing your aperture to defocus the background, the light sources 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 wide-open setting to when it is closed by 2
stops. Smoother, more natural defocusing can be obtained as a result.
SSM (Super Sonic Wave Motor) for fast, quiet and precise focusing
Focus precision is vital when working with high-resolution images and a narrow depth of eld.
A ring SSM (Super Sonic wave Motor) yields the power and precision necessary to accurately
and swily position one of the heaviest focusing groups in any interchangeable lens for
mirrorless cameras, and a new multi-sensor system plus high-speed data processing provides the
instantaneous feedback required for awless autofocus precision.
Nano AR Coating
Sony’s original Nano AR Coating technology minimizes are and ghosting, for dynamic range
that achieves lifelike detail and gradation with advanced camera sensors. This precisely dened
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 reection
suppression characteristic of the Nano AR Coating is superior to conventional anti-reective
coatings, providing a notable improvement in clarity, contrast, and overall image quality.
Dust and moisture resistant 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 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.
ED and Super ED glass reduces are and ghosting
ED (Extra-low Dispersion) and Super ED glass elements take axial chromatic aberration and
chromatic aberration due to dierences in magnication out of the picture, maximizing resolution
and bokeh while leaving precisely rendered edges with no fringing or unnatural coloration.
Advanced simulation techniques control bokeh right from design
The G Master series elevates resolution to unprecedented heights thanks to new technology
specically developed to accommodate the more exacting tolerances required in the face of
continually evolving camera body performance. Sony has applied the most advanced optical
technology available in innovative lens elements, optical path design, simulation, testing, and
calibration, achieving image detail and sharpness that reveal the essence of every scene and
subject.
Instant auto/manual focus selection
Instantly and quickly switch between auto and manual focus via an AM/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
Once you’ve adjusted focus to where you want it, pressing this button on the lens barrel will
keep the lens locked to that focusing distance. The preview function can also be assigned to this
button through the camera’s custom settings.
