Using dimensions and weight, the portability grade of the K-01 and A7 III is 76 and 63 respectively.

More often than not, it can be tough to envision the gap in sensor sizes just by looking through technical specs. The picture below might give you a better sense of the sensor measurements in the K-01 and A7 III.

As you have seen, both of the cameras enjoy different megapixels and different sensor sizes. The K-01 using its smaller sensor will make shooting shallower DOF more difficult and the Sony A7 III will provide you with greater detail having an extra 8 Megapixels. Greater resolution can also enable you to crop images far more aggressively. The more aged K-01 will be disadvantaged when it comes to sensor innovation.
