EE, what camera are you using? What quality setting? Are your lenses able to shoot in low light? i.e. f/2.8 or lower etc? Also, just a tip, shoot in the RAW, when you go to crop your shot it won't lose pixels as it would in JPEG.
My camera gear is as follows:
Nikon D700
Nikkor 70-200mm f/2.8
Nikkor 24-70mm f/2.8
Nikkor 17-35mm f/2.8 (Wide Angle)
Nikkor 50mm f/1.4
SB900 Flash
I still need a few things, but gear wise I'm pretty set. I'll try to remember to post my pics when I get home.
