Secondly, cameras should be compared with the very same lens strapped in front of them and if possible, with the same setting too. And that's how I know for sure that my NEX + FA43 give so much better results then my K-5 + FA43. Same lens, same sensor, different camera body. The latter should be the explanation for the difference in results.
I just see a lot of people here in these threads that have invested lots in K-mount lenses, and can't or won't make the switch to a platform with full frame, be it Canon, Nikon, Sony or (in the near future)
Fuji. That's proprietary for you. A much bigger ball and chain then proprietary batteries or cables.
I take it you don't know much about cars. Yes, that is exactly what I'm saying, and you're giving me the reason with yet another example. A Lotus Elise has a Toyota engine, say, a Camry. Is it the same car? Will it give you the same performance? Absolutely not, not in a million years. Take Ford's Duratec engine, used in the Mazda CX-9, Mazda 6, Ford F-150 and Ford Mustang [to name a few]. Same car? No. Same performance? No. Same use and target market? Nu-uh.
So yes, the same Sony sensor can be used in a Sony, a Nikon and a Pentax camera, and will most definitely be a better choice one or another. How? Could be user's preference, or the intended use for a certain type of camera.
Now, what you're saying is totally illogical because if you use the same sensor and same lens,
then the RAW image will forcefully be the same. The JPEG on the other hand, would not, and the performance would not either -by performance I mean shutter lag, buffer size, burst rate, and the layout that allows the photographer to be more versatile and/or faster with the settings to get a shot, such as buttons, weather sealing, whatever the camera offers other than the sensor.
And regarding lenses, well, that's how it is with cameras, always has. But manufacturers use standards to give the user the freedom of choice. Sony never does that, be it with the Memory Sticks, the UMD discs, the chargers, the hot-shoes.. just google Sony's reputation in proprietary stuff and you'll see I'm not making this up.
