Pentax K-7 vs Pentax RS1500

Lets look a bit more closely at the Pentax K-7 vs Pentax RS1500, former is a Advanced DSLR while the latter is a Small Sensor Compact and both are built by Pentax. The image resolution of the K-7 (15MP) and the RS1500 (14MP) is pretty well matched but the K-7 (APS-C) and RS1500 (1/2.3") provide different sensor size.

The K-7 was revealed 17 months prior to the RS1500 which makes them a generation away from one another. The two cameras have different body design with the Pentax K-7 being a Mid-size SLR camera and the Pentax RS1500 being a Compact camera.

Before we go right into a in depth comparison, here is a quick highlight of how the K-7 grades versus the RS1500 with regard to portability, imaging, features and an overall mark.

For those who are planning to travel with your camera often, you have to think about its weight and measurements.

Remember that, the weight of an ILC will change depending on the lens you select at the time. Below is a front view overall size comparison of the K-7 against the RS1500.

Using dimensions and weight, the portability score of the K-7 and RS1500 is 60 and 93 respectively.

Normally, it's hard to picture the difference between sensor dimensions merely by checking specifications. The image here will help give you a stronger sense of the sensor measurements in the K-7 and RS1500.

Plainly, both of the cameras provide different megapixels and different sensor dimensions. The K-7 using its bigger sensor is going to make achieving shallower depth of field easier and the Pentax K-7 will resolve greater detail because of its extra 1MP. Higher resolution will also let you crop shots more aggressively. The more aged K-7 is going to be disadvantaged in sensor technology.
