Two years ago I was a Nikon Fanatic. Now I find myself shooting an Olympus camera, equipped with lenses made by Olympus, Panasonic, Sigma, and Rokinon. I'm about to head North for Xmas with an ultra-light 5 lens kit that's every bit as capable as a kit of my beloved Nikkors. Going Native Nikon began introducing DX lenses in 2003, and we believed it would result in much smaller, more affordable lenses. It didn't happen, but u4/3 has delivered on that promise.
