If dxomark is correct, the sigma 18-35 is the highest resolving zoom period and yeah its probably out-resolving the k-3, at least in the center. It is true that you want the sensor to out-resolve the lens in an ideal situation. Consider that with a bayer pattern you are losing resolution due to the CFA anyways. All those issues associated with bayer (moire,etc) go away as the density increases. Photosites are like buckets though. The smaller they are, the less rain they collect. DR is hurt and so is sensitivity. I think sensor technology has some ways to go on sensitivity, so I'm pretty sure they can keep making the photosites smaller as they remove more of the crap that is sitting on top of them without too much detrimental effect. Look at what the A7S is capable of with a 12mp sensor produced with modern sensor technology compared to say a D700. The current sony exmor sensors are not using the full area of the photosite that is possible for instance. Sony has a new BSI sensor for camera phones that pretty much utilizes the full photosite. It will be interesting to see when that scales up to much larger chips. The future is bright indeed.
