Choosing the lens first, then only selecting the body.

If you're talking about portraits(and not shooting directly at the sun like switchfx said) wouldn't a polarizer or a neutral density filter generally fix this problem anyway?

no, the issue is becuase the light source is too bright for the CCD and you get blooming.

Stopping it down with a filter wouldn't help with needing the very fast shutter speeds or with the blooming? I'm not sure I understand...
