Any camera will perform well enough in ideal conditions. Its how well it handles outside those conditions that matter.
Any camera will degrade in performance when pushed outside its limits. The key here is how far is that limit.
Each and every person will have a different level expectation from the final output.
The meter Auto in this case is a means to the end and varies camera to camera... exposure is the only goal which can be duplicated in any mode. Again nothin being proven except the quality and accuacy of that particular meter.
The parameters are not specified nor being quantively measured. We are just left looking at websized examples of photos that are not even identical.
Conrad, the exercise is full of variables and holes that you are not addressing and the conclusion or point being made is essentially pointless. In my lifetime, I have shot al sorts of equipment. I have produced quality pictures with each and every unit. I have also produced crap from each and every unit. Ranging from a low end PS, high end PS, small sensor micro 43, crop high end DSLR, full frame DSLR, to a high end full frame digital Rangefinders. In the professional field there are photogs that are highly equipped and lesser equipped all earning a living according to the constraints of their profession and business expense.
I have no doubt that most photogs would experience the same exact thing and come to the same conclusion.. Cameras are simply enablers. Nothing more.
And before you clump me in with the other camp of opinions from which you disagreed, you should do a search and understand that I have argued the position that even a low end Point and Shoot has its place in the market.. posted quite a few pics from them and also translated into how I approach someone shopping for a camera.
