Often, it can be difficult to visualise the contrast between sensor sizing simply by going over a spec sheet. The visual here may give you a far better sense of the sensor measurements in the R and A7S III.

Clearly, the 2 cameras feature the identical sensor size but not the same MP. You should expect to see the Canon R to offer you extra detail as a result of its extra 18 Megapixels. Greater resolution can also let you crop pics way more aggressively. The older R is going to be disadvantaged with regard to sensor innovation.
