Doesn't seem to be more than a nickel's worth of difference in these examples*. I believe that the noise reducing algorithms in the cameras are responsible for the slight differences seen. Although newer sensor production technologies provide lower thermally generated noise than prior generations of sensors, post processing of the image in camera plays an important role in the reduction of noise and the sharpness of the image. The general zeitgeist concerning pixel size and density seems to be somewhat refuted by the results obtained with the Canon 20D! Begs the question: is aggressive noise reduction destroying image details? Kirbic alluded to loss of fine detail and I think he is right. Post processing is yielding an image that appears sharp but is still missing very fine detail. Another factor that affects detail in the image is the anti-aliasing (AA) filter placed between the lens and the sensor. Our digital cameras are pretty darned good, but there is always room for improvement!
*Except for the Olympus E300

Aha, thanks for the link. I know Miljenko from the DPReview forums. He is a very reasonable person, and I trust his ability to conduct a test properly. However, as I already said, there are no surprises in the results.
It's interesting that the reviewer himself, having conducted the review, chose to buy a Nikon camera over Canon. Just another evidence to the point that noise performance is not everything.
Here's a relvant quote: Canon cameras are well known for superior high ISO noise performance. Anyone trying to prove the opposite either is a liar or performs an uncontrolled testing. Even this test contains a questionable D200 pic that is suspected to have worse noise level than shown. However, noise performance is not everything. I have chosen few other Nikon virtues over the Canon's low noise although lower noise would made me much happier. |
Miljenko didn't do the tests, he did some editing (adjust WB) and compiled them from Digitalcamera.impress.co.jp. He has a disclaimer at

The noise vs loss of detail is shown at //www.dpreview.com/reviews/canoneos5d/page21.asp and here //www.dpreview.com/reviews/nikond200/page21.asp

Thanks for another clarification. I didn't think of going one level up when reading the page. |
