Olympus SH-3 vs Pentax K-S1

On this page, we will be looking at the Olympus SH-3 and Pentax K-S1, one is a Small Sensor Superzoom and the latter is a Advanced DSLR by competitors Olympus and Pentax. The sensor resolution of the SH-3 (16MP) and the K-S1 (20MP) is relatively well matched but the SH-3 (1/2.3") and K-S1 (APS-C) have totally different sensor sizing.

Normally, it is very tough to visualise the gap between sensor sizes merely by checking technical specs. The picture below might give you a greater sense of the sensor sizing in the SH-3 and K-S1.

As you can tell, both the cameras provide different resolutions and different sensor sizes. The SH-3 using its tinier sensor will make getting bokeh more challenging and the Pentax K-S1 will give you greater detail with its extra 4 Megapixels. Higher resolution will enable you to crop shots more aggressively. The newer SH-3 is going to have an advantage with regard to sensor tech.
