    Exactly. Now you know (one reason) why the birdwatchers and voyers think
    digital is wonderful. (The other being the better image quality at higher
    ISOs.)

    And why a lot of people won't be upgrading to the 3D, even if it uses the
    same sensor the 1Ds does. The anti-digital types who think the 10D is going
    to be obsolete soon are quite wrong<g>.

    Thanks for the clarification. I have 7 Nikkor AF lenses that I have been using
    with my F-4. . These lenses are pre D. Will I have any problems using these
    lenses with the D-100? I have seen several threads on this subject that seem
    more in conflict than agreement.

    Yes, but the DOF doesn't change at all with the 1.5x factor. It is more
    accurate to think of it as a crop of a 35mm frame, stated as a angle of
    view. You can't go wrong from that way of looking at it. People would
    be less confused, I think, if the common parlance were "angle of view"
    instead of "mm-equivalent".

    DOF in a 45mm lens is the same in the 5x tele zoom of a Sony F707,
    normal view in 35mm, and wide-angle in medium format. They're just
    different crops based on the size of the medium. Even if you speak in
    terms of "35mm-equivalence", never forget the absolute lens.
