I am going to be purchasing a new camera here pretty soon. I currently have a Sony a200. I really like the Sony DSLRs, but I have started to like Nikons quite a bit recently. Here's my choices. I am either going to buy a new Sony a700, or a Nikon D90. I currently have 3 lenses for my Sony a200, and spare batteries. I could sell all of this stuff if I switched to Nikon. Or I could use it if I get a Sony a700. From what I have read, both are good cameras. My main consideration with Nikon is the popularity of them, which means a better choice of lenses and accessories. If you own either a Sony a700, or Nikon D90, how do you like them?
