    Please convince me that my thinking is flawed:

    1) I started shooting with the EF-S 18-55mm wide open and was
    disappointed with the lack of sharpness. So...

    2) I purchased an EF 17-40mm F/4L and shot with *that* one wide open
    and was not satisfied with the shallow depth of field. So...

    3) I stopped down the 17-40mm to f/11 and got nice pictures. But...

    4) I also get nice pictures with the 18-55mm at f/11.

    5) I am brooding that I wasted $800 on the better lens.

    The 17-40 is a much better lens, but can the sensor in the 300D actually
    resolve enough detail to take advantage of it? Based on what I've seen, no.
    Still, it's a nice lens, and not a waste of money, not by a long shot.
    Higher resolutions will come along, and you'll still have that nice lens.

  3. A) Shoot with both and compare at f/5.6, not f/11.

    B) The 17-40 focuses faster and offers full-time manual focusing.

    C) Compare flare and contrast.

    D) The 17-40 can be used on all other Canon EOS film and digital bodies

    How do you like them when they are stopped down only a little bit, e.g.
    f/5.6 or so?

    In message <alssb.170$>,
    Only the "L" telephoto primes have the kind of resolution that goes much
    beyond what the 6.3mp Canon DSLRs can record.

    These cameras attenuate the sharpest details, as a necessity, to cut off
    frequencies that would record as garbage. You can bring back the
    details by using a very strong unsharp mask of 0.3 to 0.7 pixels.
