Epson R-D1x vs YI M1 Overview
In this write-up, we are looking at the Epson R-D1x and YI M1, former being a Advanced Mirrorless while the other is a Entry-Level Mirrorless by companies Epson and YI. There exists a sizable gap between the sensor resolutions of the R-D1x (6MP) and M1 (20MP) and the R-D1x (APS-C) and M1 (Four Thirds) enjoy different sensor measurements.

The R-D1x was revealed 8 years before the M1 and that is quite a significant difference as far as technology is concerned. Each of the cameras offer the identical body type (Rangefinder-style mirrorless).
Before going through a more detailed comparison, below is a short introduction of how the R-D1x matches up versus the M1 in regards to portability, imaging, features and an overall grade.

Epson R-D1x vs YI M1 Sensor Comparison
Normally, it's tough to imagine the gap between sensor measurements just by looking at a spec sheet. The photograph underneath may offer you a clearer sense of the sensor sizes in the R-D1x and M1.
Clearly, both the cameras offer different megapixel count and different sensor measurements. The R-D1x having a larger sensor is going to make achieving shallow DOF easier and the YI M1 will resolve greater detail because of its extra 14 Megapixels. Greater resolution can also make it easier to crop images a little more aggressively. The older R-D1x is going to be disadvantaged with regard to sensor innovation.
