Key Features

  • Full-frame E-mount mirrorless cameras have a standard zoom
  • When using an APS-C camera, the comparable focal length is 42-105mm
  • A constant maximum aperture of f/2.8 is used. Use of low light and control of depth of field
  • Chromatic aberrations and colour fringing are reduced by two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) components
  • Spherical aberrations and distortion are controlled by three aspherical elements
  • Both Super Multi-Layer and NanoPorous coatings reduce lens flare and ghosting, resulting in images that are rich in contrast and colour neutral

  • The minimum focus distance for a 70mm lens is 15 millimetres", magnification 1:4.6
  • The nine-blade diaphragm is rounded for a nice bokeh effect
