Jay Coleman,

                                  >>It handles beautifully with the R8<<

That's what I was most curious about; I must get my hands on one ASAP :~)!

The other variable I'm trying to understand is it's ( 80 f1.4 ) performance at
f2 relative to the 90 f2 "cron".  Per the BAS charts, sharpness for the 90 f2 (
at f2 ) is slightly down ( contrast is great ) ; however, sharpness & contrast
for the 80 f1.4 ( at f2 ) are not computed. It's hard to extrapolate it's f2
performance as the curves are only given for f1.4, f4, & f8! 

Surely, there's a LugNut out there who knows the answer :~)!
