AF-S NIKKOR 50mm f/1.4G

  • AF-S NIKKOR 50mm f/1.4G

Key Features

  • AF-S 50mm lens — a fast, single-focal-length lens with normal picture angle (when attached to a DX-format SLR, the picture angle is equivalent to a focal length of 75mm in FX/35mm format)
  • Large maximum aperture of f/1.4
  • Well-balanced design realizes both high MTF performance and natural-looking picture blur
  • Newly developed optical system effectively corrects sagittal coma flare and coma aberration
  • Silent Wave Motor (SWM) ensures smooth, quiet AF operation
  • Two focus modes are available — M/A (manual-priority autofocus) and M (manual focus)
  • Focus ring does not rotate in AF operation
  • Natural blur effects thanks to nine-blade rounded diaphragm
  • Although all lens groups shift during focusing, the lens barrel length does not change
