I have used quite a few lens with CCD cameras over the years. Nikkor 50mm F1.8 ( a good one), Canon FD 85mm, 135mm these were quite good. Pentax 67 55mm F4, 165mm F2.8 (the best).Nikon 180mm F2.8 ED (good) and a few others.

As Paul said most need to be stopped down and it makes you wonder how some of these lenses go being marketed as being really good and you see how poorly they perform.

Of these only the Pentax 67 105mm F2.8 (I think that is what it is) works fine at F2.8 with a Proline 16803 camera. The 55mm does all right as well but best stopped down 2 stops. Also using 2x2 binning helps a lot as well with some. It doesn't affect the resolution much anyway as they are so widefield. So the 55mm I used at F5.6 and 2x2 binning and similar aberrations as your sample image went away.

Greg.
