Photo Forum / Digital Photography / DSLR Cameras / July 2006Two cameras, two magazines, two opposed opinions
Magazine 1: "The D200 has less noise at high ISOs than the 30D." Magazine 2: "The 30D has less noise at high ISOs than the D200." I've seen identical scenes shot with both cameras. The D200 definitely has more (and different and IMO, worse noise) than the 30D at 1600 ISO. So how can magazines come to such opposing opinions? It's not like there is much variation from one camera to the next from the same line. > Magazine 1: "The D200 has less noise at high ISOs than the 30D." > Magazine 2: "The 30D has less noise at high ISOs than the D200."

Go into a camera shop with you CF and takes shots with both of similar subjects at ISO 1600. Take them home and examine closely. In other words, don't take someone else's word for it! =========================================================================== Chris Shocking isn't it? Everything you read may not be true! Unless it comes from the White House . . . A few tins of paint will fix that.  SignatureJoan http://www.flickr.com/photos/joan-in-manly : Shocking isn't it?

That's fine for a story where opinion can make up the bulk, but camera noise is testable and the tests if done correctly don't lie or deviate. > > Shocking isn't it?

Two different people with different opinions? What is the world coming to? >> Magazine 1: "The D200 has less noise at high ISOs than the 30D." >> Magazine 2: "The 30D has less noise at high ISOs than the D200." > > Shocking.

So, when someone's saying that 2+5 equals 5, and someone else is saying that it's 4, do you see it as just two different people with different opinions? > >> Magazine 1: "The D200 has less noise at high ISOs than the 30D." > >> Magazine 2: "The 30D has less noise at high ISOs than the D200."

If it was that simple, the answer would be obvious: they are both wrong. Actually, in this case, that is probably exactly the case. Noise comparisons are difficult. It is easy to make a noisy picture with any camera and then claim that it is noisier than some other model. Some cameras do more in-camera processing (even on supposedly RAW files) than other cameras, too, so a direct comparison is impossible. It is a trade-off. Generally, the more noise reduction you do on a picture, the less detail it will have, whether that noise reduction is done in the camera or in editing. The D200 and the 30D both have several user adjustments for noise reduction, but they both also do some noise processing even with all these adjustments turned off. So no, there is no objective measurement that tells you that one camera is noisier than another. |
