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.
