Which camera has lowest noise at high speed?

    I am looking for a good camera to take indoor portrait photos of my toddler.
    I don't like to use flash because the result is more boring than natural light.
    Tripod will not help because of subject movement.

    I believe this means I need a camera that has least noise at very high speeds.
    I want to use a large-aperture (say 1.8) lens, so that means I'll need an SLR.
    Canon rebel and Nikon d70 both support ISO 1600 - which has lower noise? Are
    there other cameras to consider (at no more than $1500)?

    Also, I notice that some higher priced cameras from these companies have lower
    ISOs. (For example Nikon D2X.) That doesn't seem to make sense.

  2. Here you can see a noise comparison between the two:

    Personally I am somewhat sceptic to the method used, but ...

    Other cameras to consider in the price range
    Pentax *istDS
    Olympus E300

    Canon 20D, of course. Low noise at high ISO is one of it's great s

  4. Like asking which commercial jet has the quietest engines, this is a
    needless question- they are both very noisy at ISO1600, and any such margins
    between them are narrow. Allegedly the 20D has best-controlled noise.

  6. Have you tried bounced flash?

  7. Hmm. Depends what you mean by "very". If you turn off sharpening and expose
    correctly, both cameras will produce 8x10 prints that are soft but quite
    clean. If you object to the softness, a slight hit of NeatImage and
    sharpening in Photoshop with the threshold bumped a bit will improve the
    prints. In either case, you get better prints than you'd get with ISO 800
    (and probably even ISO 400) films in 35mm. Also, the noise levels at ISO
    1600 in both cameras are lower than the current P&S cameras at ISO 400. So
    from those comparisons, I'd say that the D70 and 20D have phenomenally low
    Between the lower noise (see the graphs at the bottom of the page)


    And the extra pixels, the 20D should produce noticeably better 8x10s from
    ISO 1600 images.

    The 20D will outdo the rebel and 10D even more with subject areas that
    are very sharp, taken with a sharp lens. This is because the 20D has a
    weaker anti-aliasing filter, which increases the potential
    pixel-to-pixel contrast, and hence the signal-to-noise ratio at high
    frequencies in sharply focused areas of fine detail.

    This should apply to the D70 as well, since it has an even weaker AA

  9. Yes.

    But the Drebel's AA filter is already weak enough to allow the 10-22 to
    produce Moire :-(

    I do not think a weak AA filter is a feature.

    More details?

    I thought the drebel and the 10D had the same AA filter.
    JPS, Jan 12, 2005
  11. ??? I found Moire in a shot I took with the 10-22. There isn't much more to

    The good news is that it's pretty rare (only once). But the 300D's not my
    main camera, so I haven't really stressed it.
    That's my understanding, too.
