Ok, this is a legitimate question. Outside of "it doesn't matter on the lens/camera as much as your ability to shoot," how can ANYBODY afford to get into photography it seems? I have a Nikon d80 and the standard 18-135mm lens, and looking at getting into Sports photography, but really, I cannot afford the glass in which it takes to get into it. (70-200 f/2.8 for 2100? Ouch, or even more, the 300 mm f/2.8? with an optional 1.4x teleconverter?) And I'm not even thinking about upgrading my current camera to a d700 or *gasp* D3. What is the best thing to do outside of destroying my credit cards and saving for 3 years when I am just trying to get into it?
