hansolo82: Great news IF you don't use their mystical "DxOMark Score" and put that in the front page of your site (i.e. meaningless because using only one data point on the overall test, and that's for lenses AND sensors). Anyone who digs a bit deeper in their tests (and other's) will soon see that it takes more than one number to caracterize a lens (especially zoom) or a sensor. Take the canon 70-200mm f/2.8 I & II for reference.
That's why my No1 reference for lenses is now Roger Cicala's lensrental blog because : 1 - he tests as many copies as he can because he knows sample variation is important, even for a 50 000$ cinema lenses.
2 - tries to test at different focal length
3 - Gives the (average) resolution for the center and for an average over the entire coverage (although he should also gives the maximum and minimum he got in a batch)
Just unfortunate that he does really have the time to test everything he got (but at least seems to test everything that's new).
The "one number magical score" is meant for people in a hurry. For all the others DxO provides data which is detailed enough to carry out a finer analysis.

I own an A900, I would be all in the A99 for better focusing.
However I see that they have done it again, the same APS-C AF and layout used in a full frame camera, same as they did with A700-A900.
What a pity. A top-notch AF system that forces you to focus and recompose each time you do off-center composition. Not to mention the issues with moving subjects.
Oh well, I guess my turn will come with the A99 successor. It seems that Sony listens to customers as they have implemented auto-iso in M mode this time. So next time Sony, PLEASE IMPLEMENT A DEDICATED FULL-FRAME AF MODULE WITH SENSIBLE LAYOUT. Please.
