Pentax K-3 vs Pentax I-10

Its time to examine more closely at the Pentax K-3 versus Pentax I-10, former is a Advanced DSLR while the other is a Small Sensor Compact and they are both designed by Pentax. There is a noticeable difference between the image resolutions of the K-3 (24MP) and I-10 (12MP) and the K-3 (APS-C) and I-10 (1/2.3") possess different sensor size.

Oftentimes, its difficult to visualize the contrast between sensor sizes only by checking a spec sheet. The picture here may give you a much better sense of the sensor dimensions in the K-3 and I-10.

Clearly, the 2 cameras have got different resolutions and different sensor sizes. The K-3 using its larger sensor is going to make achieving shallower depth of field easier and the Pentax K-3 will give extra detail using its extra 12MP. Greater resolution will let you crop photos much more aggressively. The more recent K-3 should have an edge when it comes to sensor tech.
