Epson R-D1 vs Pentax Q-S1

Let's look a little more closely at the Epson R-D1 versus Pentax Q-S1, one being a Advanced Mirrorless and the other is a Entry-Level Mirrorless by companies Epson and Pentax. There exists a significant gap between the sensor resolutions of the R-D1 (6MP) and Q-S1 (12MP) and the R-D1 (APS-C) and Q-S1 (1/1.7") posses different sensor sizing.

The R-D1 was manufactured 11 years earlier than the Q-S1 and that is quite a sizable gap as far as technology is concerned. Both of these cameras feature the same body design (Rangefinder-style mirrorless).

Before going right into a more detailed comparison, here is a simple summary of how the R-D1 scores vs the Q-S1 in regards to portability, imaging, features and an overall rating.

The following is a sample of the gallery pictures for Epson R-D1 and Pentax Q-S1. The entire galleries are provided at Epson R-D1 Gallery and Pentax Q-S1 Gallery.

In case you're intending to carry your camera regularly, you will want to take into account its weight and volume. The Epson R-D1 comes with external dimensions of 142mm x 89mm x 40mm (5.6" x 3.5" x 1.6") accompanied by a weight of 620 grams (1.37 lbs) whilst the Pentax Q-S1 has sizing of 105mm x 58mm x 34mm (4.1" x 2.3" x 1.3") along with a weight of 203 grams (0.45 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilising during that time. Below is a front view dimensions comparison of the R-D1 vs the Q-S1.

Factoring in dimensions and weight, the portability score of the R-D1 and Q-S1 is 75 and 92 respectively.

More often than not, its difficult to picture the difference between sensor sizing merely by looking at a spec sheet. The photograph below may provide you a much better sense of the sensor dimensions in the R-D1 and Q-S1.

Clearly, the 2 cameras feature different resolutions and different sensor sizing. The R-D1 featuring a larger sensor is going to make getting bokeh easier and the Pentax Q-S1 will give you more detail due to its extra 6MP. Greater resolution will let you crop images way more aggressively. The older R-D1 is going to be disadvantaged with regard to sensor tech.
