So I've decided to go with nikon and I think that I prefer the D70s body over the D50. Now things are about to get costly. what 2 lenses should I get with the D70. I have no idea what too look for as I've never purchased lenses before. and if that gets too costly what two lenses should I buy if I end up getting the D50. I'll be trying for artistic photos such as some that I will post below. Thanks!
