I think this is the wrong site for that information! bdery is right about the microlenses, any CMOS sensor with decent sensitivity has them, including the K-5 and K-3. Along with smaller microsites (light sensitive regions of metal oxide - the MO in CMOS) the new sensor in the K-3 doesn't have an optical anti-aliasing filter like the K-5 does. Using the camera's built-in shake reduction and/or software instead of glass to eliminate moire patterns should result in a better image, but any improvement will be minor compared to improvements from the increased pixel density. in the end, human visual resolution is much lower than that of the sensor, but our perception of colour, dynamic range and depth is so superior, that we need software (computer and human) to transform the data supplied by the sensor into an image we recognize as an accurate representation of what our brains saw at that particular place and time. More data should result in better images, everything else being equal. But there are limits imposed by our eyes and brains, and the improvement gained by increasing the number of pixels is not linear. Going from 8 MP to 12 MP was more of an improvement than going from 16 MP to 24 MP.

What you are really asking is how does the K-3 compare to the most advanced full-frame DLSRs. I would think the optical differences between APS-C and FF cameras would outweigh the differences between the sensors themselves, because electronics can't do anything with light that doesn't come through the lens. I will say that changing the sensor form factor comes with a cost in terms of how the camera is constructed and the demands placed on the camera's image processor, but there are ways to compensate for those factors in order to produce images of similar quality. It appears that the K-3 sensor is state of the art for the APS-C form factor, for now, and any advantages of FF cameras over the K-3 are not dependent on their larger sensors. Considering that the debate over FF vs. APS-C wasn't entirely settled when the K-5 was the APS-C standard, and the K-3 is a significant improvement over the K-5, tells me that your choice should be over which form factor or which model of camera works better for your photography, not over a comparison of sensor specs.
