Is anyone using SLR Lenses with non SLR, C-mount, cameras? I just got a Nikon F mount to C mount adapter and am using a Nikkor 28mm lens with my Imaging Source HD Camera. My goal is to improve the accuracy lost to lens distortion and the face that most Industrial camera lenses have an MTF that drops off pretty quickly once you get away from the center of the image. Even used SLR lenses are expensive (though not nearly as expensive as a hi resolution industrial lens) so I was hoping someone here might have some experience that you might relay. Any thoughts?
