I was looking forward to Michael Reichmann's test of the Sony Alpha, as I presumed that I could base my decision to buy or not on his impressions.
My take is that Michael has found that there are significant improvements over the Alpha 900 in the noise related department, like high ISO noise and in probability DR. Michael is also right that DxO will in due turn publish the corresponding lab data.
My understanding is that the EVF is the same as on the Alpha 77 SLT. I have very mixed feelings about that EVF, I both love it and hate it.
It can be used i two modes. One mode is showing image effects, like it lightens up and darkens with exposure. In many cases it is a good thing, but in many cases it makes things worse. I really would like a real switch to flip between the two modes.
On the A77 at least Sony adds insult to injury in that that they live view histogram only shows exposure based data in the viewfinder is in image effects mode. Perhaps the Alpha 99 fixed it? I guess I need to play with the camera to find out.
Can histogram be shown simultaneously with electronic level? Not on the A77, have they fixed that on the Alpha 99?
In my view, electronic viewfinders are the future, but they need to improve.
So, am I going to buy the Alpha 900? Well, maybe. At this time I may feel that it would have been smarter to ditch Sony and go for the excellent Nikon D800 (with or without the E), unfortunately I didn't do that. What I'm lacking mostly on the Alpha 900 is live view, my Alpha 77 offers that.
In my view, Michaels review was a good and honest one.
