To make an 8 by 10 print, I too have to live without cropping, I can't imagine what size a sensor a digicam would need to be able to forego the need for full-frame composition!
That's my problem with buying a digi SLR. I have looked at the D30, Morfe. What is that? 5 Mega-doobries? Still not as good as my Hasselblad C500 ... must get that fixed!
