This lens was designed for the latest generation of larger format image sensors. It delivers top image quality for your most demanding projects.
This lens has an image circle of 23 mm. We recommend using it with cameras having a 1 or 4/3 size sensor. It features 160 lp/mm resolution at center and 80 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 a compact metal housing that moves the spherical elements independently, virtually eliminating optical aberrations across all working distances. The focus and aperture adjustments lock-down with thumb-screws to resist equipment vibration.
