kouasupra, I have the d90 with a 18-200mm VR lens. It works for everyday stuff. For indoor lighting, I have used my friend's professional lights.
I have another question. It seem that on cloudy days, my shutter speed is greatly reduced if I shoot in sports mode. With the shutter at only 1/80, the pictures are not as sharp. And if I chose the shutter-priority or the manual mode, choosing a higher shutter speed and a higher iso, the pictures are dark. Even if I up the exposure to +4.0 to compensate for the lack of natural light, the pictures doesn't have the bright natural light I'm looking for.
