i would always shoot in fx,if i need a 'tighter' view, i would use a long lens...or crop later in LR or CS3.
shooting at 5mp, if i need to crop in tighter, i may not have the resolution to play with.that's my experience.
btw,
how come your pics not sharp?
what lens you using?
and my name is spelt as Jeanie, not genie.
Oops sorry Jeanie,
Btw i'm using a slow lense, Nikkor 70-210 f/4-5.6 during the shoot. Haven't invest in a 70-200 VR yet
