Sony® Carl Zeiss® Planar T* 50mm F1.4 ZA SSM
Legendary Carl Zeiss® optics
A great camera starts with a great lens and Sony has collaborated with Carl Zeiss to create a series
of high-quality interchangeable lenses for digital SLT and NEX cameras. Precision lenses by Carl Zeiss
are prized by serious photographers and lm-makers around the world and the company’s precision
optical instruments have helped document some of the most iconic moments in human history and
ensure for the best in image quality.
A new optical design for top-end image quality
The luxurious new optical design features 8 elements in 5 groups, with two aspherical elements for
ultimate performance despite being a standard 50mm lens. The design is extremely eective at
correcting various aberrations and realizes at reproduction characteristics (minimal eld curvature)
betting the renowned "Planar" name. Moreover, the combination of a rear-focus system and
aspheric surfaces achieves high contrast from innity to close distances for clear, sharp images even
when the aperture is wide open.
Circular Aperture
With its 9-blade circular aperture, a design said to produce the most beautiful bokeh, this lens realizes
beautiful defocusing unique to Sony and meets the stringent demands of advanced-class users who
are serious about photographic expression.
SteadyShot INSIDE™ image stabilization
The SteadyShot INSIDE™ image stabilization system built into Sony A-mount cameras provides
image stabilization without aecting image quality, an advantage that supports the high depiction
performance of top-class lenses.
Quiet and smooth AF operation thanks to SSM
Autofocusing is smooth and quiet, courtesy of a Super Sonic wave Motor (SSM). Excellent focusing
performance is complemented by features including a focus hold button, a focus ring that doesn’t
rotate during AF operation, a DMF (Direct Manual Focus) function, and a rear-focus system that
maintains the same lens body length during autofocusing.
Dust and drip resistant design
The lens oers dust and drip resistance that meet the standards of mid-range models like the α99 and
α77. The main drive unit is sealed with rubber packing, etc., to realize ample dust and drip resistance
as a system when mounted on a camera to withstand tough usage in harsh environments.
High-grade metal body
The high-grade lens body is constructed of aluminum that oers both high rigidity and an attractive
nish that contributes to pride of ownership.
Carl Zeiss® Planar Lens
The Carl Zeiss® Planar lens rst became synonymous with high-performance lenses by realizing a
large aperture, at reproduction characteristics, and the successful removal of astigmatism. Once
the T* coating was introduced to dramatically reduce internal reection from its progressive double
Gauss design (with front-back symmetry), Planar became one of the most renowned lenses in the
Carl Zeiss lineup, which is synonymous with high-performance standard lenses.
Carl Zeiss® T* Coating
Coated optics were pioneered by Carl Zeiss® -- and this superb lens features T* (T-Star) coating that
virtually eliminates the lens are, internal reection and light scattering that can otherwise occur at
glass-to-air surfaces.
Superior Large-Aperture Performance
Like other large-aperture Carl Zeiss® lens designs, this f1.4 lens is simply magnicent in its ability to
capture brilliant high-resolution images in low-light conditions requiring fully open aperture.
SSM (Super Sonic wave Motor)
Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at
low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to
reshape itself quickly when voltage is applied.
Glass-Molded Aspherical Lens Elements
These precision lens elements correct distortion for sharper, more visually accurate images.
ED (Extra-low Dispersion) Glass
Because light of dierent wavelength (or color) bends at dierent angles when it passes through a
lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss® lenses to eliminate chromatic aberration by
correcting certain wavelengths of light for sharp, clear images with well-dened colors.
