Which camera has lowest noise at high speed?

Archived from groups: rec.photo.digital (More info?)

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.

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

Hubble?

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
noise<g>.

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.

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.

??? I found Moire in a shot I took with the 10-22. There isn't much more to
say...

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.
