Pentax K20D vs Pentax RS1500

Here, we will be comparing the Pentax K20D versus Pentax RS1500, former being a Advanced DSLR while the latter is a Small Sensor Compact and both are produced by Pentax. The resolution of the K20D (15MP) and the RS1500 (14MP) is pretty similar but the K20D (APS-C) and RS1500 (1/2.3") posses totally different sensor measurements.

In many cases, it's tough to envision the contrast between sensor measurements simply by going over specifications. The graphic underneath will provide you a clearer sense of the sensor measurements in the K20D and RS1500.

To sum up, the two cameras come with different resolutions and different sensor measurements. The K20D with its bigger sensor will make shooting bokeh easier and the Pentax K20D will deliver greater detail because of its extra 1MP. Higher resolution can also let you crop shots a good deal more aggressively. The older K20D is going to be disadvantaged when it comes to sensor tech.
