Quite often, it can be tough to visualise the gap in sensor measurements just by seeing specifications. The visual underneath may give you a greater sense of the sensor sizing in the A7 and a1.

Plainly, the two cameras provide the same sensor dimensions but not the same megapixels. You should expect to see the Sony a1 to produce extra detail as a result of its extra 26 Megapixels. Greater resolution can also make it easier to crop photos more aggressively. The older A7 will be behind in sensor innovation.
