Comments about Pentax C70316 1/3" 3-8mm CS Mount Manual Iris Lens:
It was an inexpensive lens probably made for a standard NTSC output camera. I am using as a spare lens only for a HD-SDI camera. I would not use it everyday on a HD cam because it is too soft of a lens.

Best bang for the buck! Superb lens and nicely made. Image quality is very good with my Imaging Source DFK21AU camera.
