Or, if you want to deflate some of the arguments, just do a side by side...it does make one feel a little silly.
I mean, this is what we are arguing about, right? The magnification in their test does vary a smidge because of different lenses used and crop, but really, this could be down to how the individual manufacturers firmware deals with the signal almost as much as the sensor. I think Pentax techs do a better job than the maker (sony) and would be really keen to see what they will do with a FF, but in reality, it is an incrimental increase...
AND... after knowing all that... I still want one! Ahahahahahahahahahahahahah! Hey, I can't help myself. That last 5% of anything is the hardest to get. Ask a drag racer who will pay untold $thousands to get an extra 25HP out of an engine, or a runner who will train insanely hard to shave off a couple hundreths of a second. We want what we want. People are funny that way.
