the only class that should be acknowledged is that of price. all cameras, mirrorless, slt, slr, dslr, P&S, or disposable all take pictures. you have to pay money for them. if what you get isnt worth the money you have to spend, you wont buy it. each camera does it in a slightly different manner, but in the end, you get a photo after clicking a button.

the a77's "class" is $1350 atm. there are 7 apsc cameras that rank above it for IQ, and all of them cost less, some, much less. so sony makes its flagship camera with an IQ that is according the DXO, the 3rd best in its lineup, yet people on here are linking lame reviews toting the a77 as the best apsc today lol. thats funny.

Your huge mistake is thinking that DxO numbers directly relate to IQ.. They don't even factor in resolution, and are very much swayed by heavy NR as just one example.

So just sticking to DR for a moment, and reading DPReview assessment of this for the A77 again, since you seem to not have read it last time..

At default settings, the A77 gives around 1.3EV more highlight range than the Pentax K-5, and around 0.7EV more than the Canon EOS 7D. The A77's dynamic range is very close to the Nikon D7000, although the highlight 'roll-off' is much smoother - the D7000's steeper curve represents a tendency for highlights to clip to white rather suddenly.

The performance gaps indicated here are essentially closed when the dynamic range expansion modes in the A77's various competitors are activated. With HTP turned on in the Canon EOS 7D, and Highlight DR activated in the K-5, the curves overlay almost exactly with the A77. The D7000's Active D-Lighting (ADL) mode is adaptive in the sense that its intensity varies scene-by-scene, so don't read too much into the results that you can see here. The important thing to notice is that with ADL turned on, highlight brightness is significantly retarded, which gives you a better chance of retaining detail in bright scene elements.

This tells me that whilst DxO might give a theoretical indication, clearly it isn't telling me the whole (or perhaps 'real' picture).. Or are DPReview lying when they say

if you subscribe to the "good enough" photog group, hey good for you. the a77 will make you very happy

Since no camera has it all, then I'm afraid that this applies to every camera.. unless you are stupid enough to limit everything down to DxO Numbers.. (Especially when they have to put a warning next to certain cameras)..
