[QUOTE="J-see, post: 418081, member: 31330"] There's a difference between the resolution of your shot and the pixels of a sensor. The more "sensor" pixels a cam has, the larger the resolution of the shot will be since the sensor pixels define that. But more does not necessarily translate into better quality or more detail. Roughly the smaller the pixels of a sensor, the better it is for detail but a lot of factors define if or if not you can grab those details. On the other hand, the larger the sensor pixels, the more accurate the signal it captures but on its own that also means little. Theoretically if you'd use two lenses on the same cam and would shoot the exact same shot, the better lens would result in a larger file size since it should be able to grab more data and thus has to write down more values in the RAW but in practice this is trivial. The better the lens, the better the image quality and the DXO scores are about the perceived quality. But if my D750 + lens scores 19 and the D810 + same lens 23, it does not imply the shot of the D810 will be much better since it's 19/24 vs 23/36. [/QUOTE]
