Epson R-D1 vs Sony A7c Sensor Comparison

In many cases, it is very hard to visualise the gap between sensor measurements just by reading a spec sheet. The photograph here may offer you a far better sense of the sensor sizes in the R-D1 and A7c.

Clearly, both of the cameras posses different megapixels and different sensor measurements. The R-D1 with its tinier sensor will make achieving shallower depth of field more difficult and the Sony A7c will offer greater detail with its extra 18MP. Higher resolution can also enable you to crop photographs somewhat more aggressively. The older R-D1 is going to be behind with regard to sensor technology.
