More info

  • Virtually zero focus shift from 450nm to 2,000nm wavelength range.
  • Utilizes Kowa’s ultra-wideband multi-coatings to increase transmission.
  • A maximum of 12 megapixel and 3.1μm performance can be found at select wavelength ranges.
  • Special extra low dispersion (XD) glass significantly reduces chromatic aberration, otherwise known as color fringing.
  • Relatively low distortion.
  • Includes Kowa’s signature floating mechanism design that eliminates optical aberrations from close distance to infinity.
  • Suitable with sensors such as Sony’s IMX990, IMX991, and more.
  • Thumb screws can firmly lock the focus and iris settings into place.
  • Made in Japan.
