    Default D60's sensor is too small to stop down below f/11

    chim.....

    Let's compare the D60 to the D30 using this formula:

    D30's pixel height to sensor height ratio: 1440 pixels / 14.9mm = 96.6 pixels/mm

    We'll be able to use f/22 without concern for visible diffraction because the ratio is less than 100 pixels/mm.

    (If you want to see how this was derived, you'll have to work through the math in my original article - at the top of this thread.)

    D60's pixel height to sensor heigt ratio: 2048 pixels / 15.1 = 135.6 pixels/mm

    This exceeds 100. We won't be able to use f/22 without inducing visible diffraction because the ratio exceeds 100 pixels/mm.
    wonder how true is this....
