Sony FE 50mm F1.8 Full-frame Prime E-Mount Lens - SEL50F18F

Large F1.8 maximum aperture enables beautiful defocusing effects7-blade circular aperture creates beautiful defocused bokehCompact, lightweight design ideal for full-frame E-mount camerasAspherical element controls spherical aberration and comaDouble-gauss configuration suppresses field curvature & distortionMetal mount adds solid durability as well as a sophisticated feelFast DC motor focus actuator system drives all lens groupsSmooth defocusingThe 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 apertureThe 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 performanceThe 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 DurabilityDesigned for reliability in a wide range of environments, the metal mount adds a sophisticated feel as well as solid durability. Fast, agile focusingFast 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.Product Specifications:Model name - SEL50F18FLens mount - Sony E-mountFormat - 35mm Full-frameCompatibility - E-mount 35mm Full FrameE-mount APS-C camerasFocal-length (mm) - 50mm35mm equivalent focal-length on APS C - 75mmLens construction (groups-elements) - 5 groups, 6 elementsAspherical Lenses - 1 asphericalAngle of view (APS-C) - 32-Degrees Angle of view (35mm) - 47-Degrees Maximum aperture (F) - f/1.8Minimum aperture (F) - f/22Number of aperture blade - 7 bladesCircular aperture - YesMinimum focus distance (m) - 0.45mMinimum focus distance (ft) - 1.48'Minimum focus distance (in.) - 17.72"Maximum magnification ratio (x) - 0.15xLens motors - DC motor focus actuatorFilter diameter (mm) - 49mmHood type - Round shape, bayonet typeDimensions dia. x length (mm) -68.6mm x 59.5mmDimensions dia. x length (in.)- 2.7" x 2.34"Weight (approx.)
