Okay, so far so good... I have tried to print the photos that had the most chromatic aberrations; the FA100/2.8 macro at f/2.8 and the Sigma APO 70-200/2.8 at 70mm and f/2.8.
The good news is that from the "suburb houses" shots, nobody would be able to see any aberrations in an A4, unless they were told what to look for and look closely. However, the aberrations in the first test shot I did with a FA100/2.8 macro (http://home.online.no/~jooksne/istd_aberr.htm) clearly shows up on an A4 print. To me, the ultimate test is to have a slide burned on film from the file and see it blown up on the wall. That's how I'm used to evaluate my shots, and feel most comfortable with.
