        Comments about Pentax C30405KP 2/3" C Mount 4.8mm f/1.8 Manual Iris Lens:

        This lens doesn't focus properly when attached to the camera. We tried two of the same lens on two cameras from different manufacturers, both C-mount. The lens had to be unscrewed approximately 1/4 turn to be in focus, which leaves them unstable. Pentax had no explanation for this problem. Oddly, the same series of lens, at narrower angles (8mm and 12 mm) had no such problem.
