another test setup for the canon 40D tests the ISO vs Noise here:

the results and methodology of the tests are different, but it provides another interesting angle by which to validate this myth

Here's another pretty cool set of pieces that might help in using DSLR's...it REALLY inspired me!

I agree completely. This test is very weak, to say the least. Of course faster shutter speeds will give less motion blur, either from the camera or the subject. That's all in here, IMO.

Thanks for your comment Chuck and I may revisit this one if we get enough comments like yours. While in a perfect lab environment the results may prove to be different but in real-world tests where you have things like wind, motion, breathing, etc to deal with, shooting at a low ISO means a slower shutter speed and thus more bluring.

Busted? Hardly. I have to say that this is a perfectly inadequate test by someone who seems not to understand what they are doing from a technical perspective.

First, critically examine the text of the article. These test shots are made hand held and at relatively large magnification. The ISO 100 shot is at 1/250 second which is well within the range for problems from camera motion, especially for a small sensor camera at close-up range. Second, carefully observe the position of the leaf in the ISO 800 shot compared to the other three shots. The leaf in the ISO 800 shot has
been pushed up and to the right by an invisible force... called the wind. So we have the camera in motion and the subject waving in the wind and we're supposed to judge sharpness.

In fact, although noisier, the sharpest photo is actually the ISO 1600
shot. Pay attention not to the leaf but to the bottom of the pot and what looks like a clump of peat moss. At ISO 1600 the 1/4000 sec shutter speed has finally stopped all motion. In fact, I'm not
completely convinced that we're not also seeing some changes in depth of field, possibly from changes in aperture. The ISO 1600 shot at 1/4000 sec should have been taken at 1/3200 sec if the light had not changed. Why was it taken at 1/4000? What aperture was used and why?

Perhaps what the tester says is true. I don't know. But you sure can't make any judgments from this test.

Thanks man. I was not aware of this. Wonder if this is true for Nikon as well.

Thanks for sharing your blog with me. I got it in my RSS reader.

Great article simple and very informative. I'm doing a weeks worth of articles on my blog TheyShootin.com. Because for beginners
myself included understanding ISO is a major step to taking better pictures.
Thanks Much.
