Kowa LF-Series includes 3 different models with focal length of 28mm, 35mm and 50mm. All lenses are optimized for extra high resolution and contrast from the center to the edge with very little distortion. Due to a minimum focusing distance of less than 30cm all 3 models are suitable for close-up applications. All lenses are especially designed for industrial applications with locking screws for the manual focus and iris setting.
