Sony FE 50mm F1.8 Full-frame Prime E-Mount Lens + 64GB Ultimate Kit

Large F1.8 maximum aperture enables beautiful defocusing effects 7-blade circular aperture creates beautiful defocused bokeh Compact, lightweight design ideal for full-frame E-mount cameras Aspherical element controls spherical aberration and coma Double-gauss configuration suppresses field curvature & distortion Metal mount adds solid durability as well as a sophisticated feel Fast DC motor focus actuator system drives all lens groups 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 a 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.
