Are you comparing an in part subjective overall camera rating from one site to an in part subjective weighing of measured results from RAW data from another site?
DPR score on many factors which are neglected by dxomark. It is perfectly unsurprising therefore when the final results are somewhat different.
No, I actually don't think the news that the A55 topped out the dxomark score for aps-c (for now, the A580 should surpass it soon) is boring at all. That's why I started a thread about it. If I'm still starting threads about it in 2 years time you can justifiably call me boring
No, I'm comparing the real-world DPR review of the 550D to the real-world DPR review of the new A55. In which the older 550D comes out ahead - which pretty much renders the DXO results useless in the real world.
There is a subtle but important difference between the methodologies used by DPR and DXO. DXO attempt to be strictly quantitative and objective. DPR are neither. Their final score is subjective and time/segment dependent. The assessment of the final suitability of a camera for a specific user cannot be simply made by looking at the final score from DPR, becuase if you use the camera for e.g. sports or portraiture the performance will be widely different. DXO does not have this characteristic. It may be flawed, but it's flawed systematically for all the cameras it tests. It should not be the basis for a decision on a camera purchase in isolation, but then, neither should the final score from dpr. You need to define what you will do with the camera, and how you will handle the work flow, then assess each camera based on these needs.No, I'm comparing the real-world DPR review of the 550D to the real-world DPR review of the new A55.

I'm pretty sure that the 550D (129x98x75), which is a very similar size to the A55 (124x92x85), is sold to many, many adults, so your poor 12 year old daughter must have freakishly large hands.
Both of which are a subjective weighing of factors of what the reviewer thought was important. That doesn't render any other comparison useless by any means, unless you and the reviewer are the same person or share the absolute same subjective standards.
See above.
- which pretty much renders the DXO results useless in the real world.
For many people the higher scientific DXO results have little to nothing to do with the real-word results when the Sony algorythm is unable to convert that data as effectively as Canon with it's lower DXO mark.
Not sure what you're referring to, but maybe the Jpeg engine, which is another subjective factor.
what are you talking about exactly? Less effective in what way? have you used either camera?
Less effective in beating the 550D (as a whole package including jpeg engine). Here we have a thread raving about the highest DXO mark for an APS-C camera yet dpreview ranked the new A55 lower than older 550D.
A hair less according to 2 subjective ratings from 3 different reviewers of one website compared.
Jim,
LOL, suddenly you believe in dxomark data... interesting
