The Sony FE 50mm f/1.8 Lens offers 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.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 ? series camera body that features in-body image stabilization, even greater low-light 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.Refined optical performance - The lens has an innovative optical design to achieve clear, high-quality images by effectively minimizing distortion and chromatic aberration. A double-gauss configuration effectively suppresses field 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.
