“And L lenses are still great. Use them now (with knowledge), and enjoy your investment in the future when you will have a camera with much better AF.”

This is why three L lenses (180 f3.5 macro, 70-200 f2.8IS and 300 f2.8 IS) would not focus accurately with two different D10s, but are spot on with my D1s?

Why would Canon release a camera (D10) with these gross errors?
