More info

  *   Virtually zero focus shift from 450nm to 2,000nm wavelength range.

  *   Utilizes Kowa’s ultra-wideband multi-coatings to increase transmission.

  *   High resolution of 12 megapixels and 3.1μm resolving power 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.
