Hi guys,
I have a D40 with 18-200mmVR and 50mm f1.8 and thinking of upgrading to D90. I thought of upgrading when I took pictures in a concert with the 50mm f1.8. Manual focus is really tough when the subject is moving and I wish the ISO performance of my D40 could be better. I didn't use an external flash as I prefer natural lighting. Has anyone got an idea if the D90 is significantly better than the D40?
