    Anyone know how much vignette there will be With the 1.0" Pentax 12.5mm CCTV, will it be acceptable or horrible?

    I am not familiar with that one but I tried two other 12.5s and the problem was not vignetting but infinity focus. They were too wide for my adapter and couldn't get close enough to the sensor. Some lenses can be modified, some can't. Never heard of one that works right out of the box. YMMV.
