The Sony SLTs never had the same image quality and high ISO performance compared the the Pentax K5, Kr, Kx. (mainly based on ImagingResource)
They have always looked less detailed (either due to heavier NR or light loss via the SLT or whatever, I don't know)
At a cursory glance, the A77 photos seem to be just larger (24mp) than the A55, with no real improvement to noise of detail retention.
If we can 'extrapolate' the performance between A55 and K5, then the new Pentax K? will be better than the A77 in rather similar ways like the former two.
That only means a larger MP version of performance than the K5 had...... not too big a deal....
In a way I am evilly glad that the A77 isn't showing any real improvement to the K5 and by extrapolation the new K?.
It just means that I don't need to spend money getting the new K?
Unless of course, the new camera will have much better AF, etc to entice me.
The A77 shots on ImagingResource do look suspicious though.
The ISO50 shot does not even seem to be focused on the targeting board.
How come even for the ISO50, 3200 shots, the text on the back of the book the lady is holding is not even clearly visible? (seems like focus was elsewhere of DOF was not the same as the K5 test)
