In a recent post I went on the offensive, criticizing Nikon for their overweight bodies and lenses. And yet, I own a Nikon. And I’m not ready to jump ship just yet. Why? As Nikon is currently promoting its newest DSLR offerings, the D3100 and the D7000, I’m drooling for an upgrade to my old D80. But, realistically, why would I pay the price premium to continue investing in the Nikon system? Why not Canon, Sony or Pentax? As we now know, it’s not for saving weight.
