DXO Mark

[Graham_of_Rainham]

Has anyone used or is anyone taking any notice of the DxO Mark test scores.

What I found interesting is the way the scores have stayed fairly flat wrt time, such that cameras made in 02 had a score of 62.5 and they now have a score of 62.9

The other interesting thing is that to get a camera with those scores in 2002 cost 2700 and in 08 cost 1300

Once you look at the cost per score point things quite interesting
It could be viewed as a Value for Money factor which may well become a deciding factor for many in the future

Not sure I follow?

That's because you lead the way

I should have perhaps said cameras with comparible scores.

This quoted from their site

http://www.dxomark.com/index.php/eng/DxOMark-Sensor/DxOMark-metrics

"DxOMark Sensor is an objective scale designed to simplify comparison of digital camera RAW-sensor performance in typical, real-life photographic scenarios.

To build this scale, we have identified a set of representative scenarios and determined their associated image quality metrics. The final DxOMark Sensor scale values are computed from these metric values."

I just happened to find their way of applying a "Score" interesting and the comparison chart provided the info on which I made my comments and hence posed the question.

I also was looking through DIWA Labs site, which again i found to be interesting.

I guess being an engineer, I like "techy" stuff

Well, scores have tended to be in the same ball park over time, but actually we see that the flagship model quality filters down to the entry-level. Look at the Canon EOS-1Ds (Mark 1) in 2002 and compare with the Canon EOS-20D in 2005; they have the same score but the latter camera is a fraction of the cost and has a much smaller sensor area.

DxO has designed the scoring system to be infinitely scalable, so while there are cameras now in the mid-80s, we will have cameras exceeding 100 eventually.
