Nikon NIKKOR Z 40mm f/2

  • Camera compatibility: Compatible with FX and DX format Nikon Z series mirrorless (on DX-format cameras, the lens has a field of view of 60mm).
  • Fast & quiet Autofocus: AF System greatly suppresses focus breathing to prevent angle-of-view shifts during recording: also allows for smooth iris adjustments with the click-less control ring to create a natural shift in brightness..
  • Custom control ring: Customize the way you shoot. Use it for precise manual focusing or to adjust aperature, ISO, or exposure compensation..
  • Beautiful background blur: The shallow depth of field of f/2 is enhandced by the lens’ 9 rounded blade diaphragm, creating a natural bokeh effect..
