  • The NIKKOR Z 20mm f/1.8 S is an S-Line lens that can capture high-resolution images stably across the entire frame even at the maximum aperture, regardless of shooting distances.
  • Users can enjoy dynamic photo expression in high resolution with an ultrawide-angle 20 mm lens that provides a wider field of view than the human eyes.
  • By effectively compensating sagittal coma flare from the maximum aperture, small light sources such as stars in astrophotography can be beautifully reproduced even at the periphery.
  • Thanks to a bright f/1.8 maximum aperture, a higher shutter speed and lower ISO sensitivity can be selected, enabling users to emphasize the subject utilizing a shallow depth of field.
  • Via the adoption of a multi-focusing system, superb imaging performance is delivered across the entire shooting range including close distances by effectively reducing aberrations.
  • Nano Crystal Coat effectively reduces ghost and flare caused by incident light, resulting in clear images even when a light source is located within the frame.
  • Easy-to-operate control ring to which various functions such as focus (M/A), aperture or exposure compensation can be assigned facilitates comfortable still and movie shooting.
  • Genuine movie recording performance has been achieved by intensive consideration even of details such as minimized operational sound, stable aperture control and effective focus-breathing compensation.
  • Electromagnetic diaphragm mechanism provides accurate, stable aperture control even during continuous shooting.
  • Lens body was designed while carefully considering dust- and drip-resistant performance for enhanced reliability.
