Low Light Lenses by Kowa

These ultra-fast lenses are intended for applications with very low illuminance. The extremely large apertures of F/0.85 and F/0.8 allow for imaging with higher image illuminance and reduced shot noise under complicated conditions such as inspection or observation at low illuminance. The electronically adjustable aperture facilitates adjustment under changing environmental conditions.
