No, no personal direct comparisons, just from experience, information on the
lists, and, most importantly, Gary Reese's lens tests which I will quote
here, without permission. Not the progression from D Grade, to C Grade to B
Grade at f/1.4 through the three formulations.
In real life, though, the differences are much more subtle. All are fine
lenses.

Tom, why the best ?
This is an old matter.
Do you have a test side by side of the lenses 1.4 MC >1000xxx vs 1.4MC
<1000xxx on a normal landscape, street scene, etc ?
