heres a repost of the data on a 6Mp FF sensor vs a 6MP APS sensor vs. lens resolution.
----------------------------------------- lens % more TOTAL RESOLUTION lp/mm of FF Sensor vs. APS Sensor 200 4.877246795 190 5.413011111 180 6.034483302 170 6.76054889 160 7.61545148 150 8.630661446 140 9.847515377 130 11.32098694 120 13.12512934 110 15.36099027 100 18.16814884 90 21.74139353 80 26.35410579 70 32.38840375 60 40.36516268 50 50.94376158 40 64.79643351 30 82.12404598 20 101.4719616 10 118.1540215 ----------------------------------------- As you can see, once the lens resolution gets below say 140 lpmm, there is at least a 10% improvement in going FF and that increases dramatically as the lens resolution goes down. And dont forget even perfect lenses cannot acheive the highest numbers on the chart when stopped down for greater DOF for diffraction reasons. It seems to me that unless you are using the finest lenses at the ideal aperture, you are going to get signifigant resolution improvement by going FF vs. APS for a 6Mp sensor. Couple that with better noise characteristics of a FF and the ability of your wide lenses to remain wide, I dont really see any advantage of APS other than cost and/or maybe smaller size of the camera and lenses (if you bought special APS lenses instead of 35mm lenses).
