The Kowa LM12JC5M2 lens delivers great image quality for demanding projects.
We recommend this lens for cameras having pixels of about 4 microns or larger. Or any time you need better resolution or improved contrast. It delivers 160 lp/mm resolution at center and 125 lp/mm in the corners. Kowa’s wide-band multi-coating reduces glare and refraction. Expect high performance even with the iris fully open.
This lens has an image circle of 11 mm. Pair it with cameras having a 11 mm (2/3 format) sensor or smaller.
This lens's compact metal housing moves the aspherical elements independently, virtually eliminating optical aberrations across all working distances. The focus and aperture adjustments lock-down with thumb-screws to resist equipment vibration.
