Wow!  I'm very impressed.  I've tried a Nikon 300 ED F/2.8 and never got close to
that performance.  A few additional questions:

1) How did you focus it?

2) Did you have any additional filtering in line (UV or Sky)?

3) What body did it mate to (Nikon or Cannon)?

4) How much?

This might be an ideal lens for use with an ABG CCD like the ST-2000.  I wonder
if RoboFocus could be adapted to drive it.
