Upgrading my faithful 450d - lens or body?
At the moment I am shooting with my 450d with a 28-135mm and a 75-300mm (which I'm not hugely impressed with at all).
I shoot a lot of sports/surf photography and am looking at the 100-400mm L lens or something similar from Sigma - I want the longer focal length for capturing the surf further out and I cover some sailing events from the shore also.
I'm looking at upgrading my body to the 7D with the improved FPS or the 5D Mark II with the FF sensor which will be great in low light.
What should I do!? Glass is expensive but bodies are updated so fast! I think I may have a case of 'new body envy'...
Advice would be appreciated.
