Pentax K-7 vs Sony RX10

Here, we will be reviewing the Pentax K-7 and Sony RX10, one is a Advanced DSLR and the latter is a Large Sensor Superzoom by rivals Pentax and Sony. There exists a crucial gap between the image resolutions of the K-7 (15MP) and RX10 (20MP) and the K-7 (APS-C) and RX10 (1") provide different sensor dimensions.

The K-7 was brought out 5 years earlier than the RX10 which is quite a serious gap as far as technology is concerned. Both the cameras feature different body design with the Pentax K-7 being a Mid-size SLR camera and the Sony RX10 being a SLR-like (bridge) camera.

Before we go into a comprehensive comparison, here is a short overview of how the K-7 scores against the RX10 for portability, imaging, features and an overall score.

Sometimes, it is very hard to picture the contrast between sensor sizes only by looking at a spec sheet. The pic underneath will help provide you a clearer sense of the sensor sizes in the K-7 and RX10.

Clearly, both the cameras come with different megapixel count and different sensor sizes. The K-7 featuring a bigger sensor is going to make shooting shallow depth of field easier and the Sony RX10 will give you more detail having its extra 5MP. Higher resolution will allow you to crop photographs a good deal more aggressively. The more aged K-7 is going to be behind when it comes to sensor innovation.
