Mark -- The Sigma 24-60mm f/2.8 and the D700 is a great combination. And what I particularly like is that the Sigma lens is a true wide angle when shooting at 24mm with the D700. My other cameras are a D70 & a D80, which means 28mm was actually 42mm. In my work I take a lot of group shots, so it's great to now have more reach on the wide end with the Sigma. I don't generally gush, but the D700 is just a dream come true.
