Dave over at Imaging-Resource has completed the mammoth task of reviewing Nikon's D1. Here's a comment he made "One thing that we did that was a little unusual was to run resolution tests on a fairly wide variety of different lenses. Turns out the D1 really shines with good glass, really shows up the limitations of the cheap stuff. (Don't know that I'll ever look at my Tamron 28-300 mm "vacation lens" the same again. OTOH, I'm now more impressed than ever with the sharpness of my Micro Nikkor 105 f/2.8.) A note for the future for all of us: Lens choice really does make a significant difference in resolution on the pro digicams. "
