Need help deciding whether to buy a new camera body or a good lens??

[Daniel Browning]

will the 70-200 also help me get better pictures when i shoot at high ISO setting such as ISO 800??

No. The only exception is if you compare a 200mm shot vs. a 70mm shot that was cropped to match 200mm. That is the only time it will look better.


If you want better pictures at ISO 800, you need a faster lens (which means thinner depth of field and more difficult to focus) or a camera with improved technology. The Canon 7D is a big improvement.


I suggest you consider the 7D and the 85mm f/1.8. That combination will do just as good as the 5D2 and 70-200 f/2.8, and far better than the XTi.
