For a given light condition, in aperture priority, should it then not matter what the aperture is set to because the camera will set the shutter speed to compensate for different aperture settings and hence give the same exposure? In which case my test should be somewhat valid. Or am i thinking priority shooting all wrong?

Interms of exposure, yes the camera should adjust the shutter speed and ISO to compensate. The issue when comparing quality at different appartures that with less light coming through the lens on one you are either introducing more blur through a lower shutter speed or more noise through a higher ISO. Either way the final image quality will be reduced in a low light situation as there is only so much movement that stabilisation can counter.

This is why people take pay much more for faster lenses (that and the added depth of feild control).

Photography is all about light and how you control and adapt to it. a test that only lets in half the light in one scenario compared to the other is invalid if you are trying to compare quality. The only way to compare the quality of the camera (ie the actual sensor) is to have the same amount of light coming in, therefor the same aparture.

As someone else mention, if your EV comp is set to zero and you have the cameras set to multi point metering mode. Then there is a problem with your Sony camera.
