Sony SEL50F18F Specifications
SEL50F18F
Full-frame E-mount Fast Prime Lens
This 50mm Full-frame E-mount Fast Prime Lens oers a
focal length that is perfect for portraiture and a range of
other subjects. A bright F1.8 maximum aperture, 7-blade
circular aperture and aspherical element deliver
impressive image quality with beautifully defocussed
background bokeh, all in a surprisingly compact and
lightweight package
Key Features
Smooth defocusing
The F1.8 maximum aperture opens up a world of beautiful prime-lens bokeh. The large F1.8
maximum aperture is also an advantage when shooting night scenes or in dimly lit interiors. When
used with an α series camera body that features in-body image stabilization, even greater lowlight capability enables handheld capture of clear images in dark scenes without having to use
excessively high ISO sensitivity.
7-blade circular aperture
The 7-blade circular aperture maximizes the beauty of large-aperture prime-lens, contributing to
impressive images in which the subject stands out against a smoothly defocused background
bokeh.
Rened optical performance
The lens has an innovative optical design to achieve clear, high-quality images by eectively
minimizing distortion and chromatic aberration. A double-gauss conguration eectively
suppresses eld curvature and distortion, while a precisely placed aspherical element controls
spherical aberration and coma for excellent optical characteristics right out to the image
periphery. An aspherical element in a new optical design controls all types of aberration
(spherical, coma, distortion), rendering the subject with superior sharpness.
Solid Durability
Designed for reliability in a wide range of environments, the metal mount adds a sophisticated
feel as well as solid durability.
Fast, agile focusing
Fast and accurate autofocus is achieved with a newly developed DC motor focus actuator
system which drives all lens groups for optimum focus precision and speed as well as quiet
operation.
