I got my D90 about this time last year as an upgrade from a D40. Over the past couple of years I have amassed four lenses. The Nikon 50mm f1.4 afs sigma 10-20 f3.5, sigma 18-200 3.5 and the nikon 18-55 3.5. I will be starting a degree course in photography later this year but still have one last college project before I go. I mostly shoot night landscapes. I will be travelling to the West Coast of America in March to shoot my final project and want it to surpass everything I have done before. I was considering a D700 as it's just about affordable. I have been reading reviews etc but want some real opinions on the camera from you guys here. How is it's ISO? what's the max you can shoot at before it becomes too noisy? Which of my lenses will work with it? Just the 50? How good will it be for night landscapes and long exposures?? Battery life similar to d90?? etc. Any opinions are greatly appreciated. P.S. if I get the D700 should I try and get the 24-70 2.4????
