>>2609784The chart in OP's pic doesn't mention anything about aperture at all. In the middle of the zoom range, at f/5.6-f/8, the kit lens is going to resolve more than 9 megapixels.
Also, as sensor resolution increases, regardless of lens sharpness, you're going to gain more detail. While it may seem not true that simply adding more pixels will make a soft lens appear sharper, it is. Belive it or not, there is a tiny bit if detail difference in betweem those pixels that are capturing soft detail. Adding more pixels, say, four small pixels capturing what only one was before, would bring out the tiny differences that the lens is projecting into that tiny area. While it may not be a huge step up in detail, there would be -some-. It may not even be noticable, but there would still be more detail regardless.
This is proven over and over by a certain camera that was released recently. The Olympus E-M5 II. If these "lens MP scores" were to be believed, then the high res shot mode on the E-M5 II would not capture any more detail at all than the standard 16mp mode. Even when using the kit lens, this has proven to not be the case, time and time again. According to DxO scores, which the idiot in the video is most likely citing, the Olympus 45mm 1.8 can only resolve 9mp of detail, regardless of what sensor it sits in front of. This was proven terribly incorrect when the E-M5 II came out with the high res shot mode. See :

Try it out yourself, if you have two different resolution bodies that can take the same lenses.
