Proof is harder to obtain than you think

Sony did us a favor and I found the samples I was looking for. They built a 24 MP SLT APC camera and a 16 MP SLT APC at basically the same time so we see the costs of smaller pixels IN THE SAME GENERATION of sensor.

Problem #1: The 'same generation of sensor' is an undefined term. You can't assume that these two sensors and their supporting hardware and firmware are identical in all ways other than resolution just because they appeared in cameras that were released closely in time. In reality we don't know what other important differences there might be.

Similar technology, same sensor size. MORE PIXELS CREATES MORE NOISE because the signal output of the pixels is less but there are fixed noise contributors. So more pixels in mid to lower light areas will be about noise not the shot. Images with areas of dark will show noise there.

Problem #2: Really? Always? You are using DPR comparisons to support your ideas, so try going to the DPR comparsions between the A7 and A7R to find the same proof of those assumptions. If you don't find the difference you were expecting, you can claim that they are not 'similar technology' even though they were released simultaneously in almost identical bodies... but then you are stuck in a circular argument that cannot be resolved.
