I am looking to buy a D70 sometime this year. I have shot my friends quite a few times and I love how it feels, shoots and its results as well. Since I have never had a DSLR I know nothing about lenses. So could someone give me the low down? What companys are good, what are bad, what mm is needed for what. I shoot a lot of action sports so I will need a lense for that. And what is a good lense for just all around photography? Where can I get the best deal on a D70 as well. Anyone want to sell me theirs for a good deal?!
