Pentax KP vs Pentax RS1500

Its time to take a deeper look at the Pentax KP versus Pentax RS1500, one being a Advanced DSLR and the other is a Small Sensor Compact and both are sold by Pentax. There is a crucial difference between the image resolutions of the KP (24MP) and RS1500 (14MP) and the KP (APS-C) and RS1500 (1/2.3") enjoy totally different sensor sizing.

The KP was released 5 years later than the RS1500 and that is quite a serious gap as far as tech is concerned. Both of the cameras come with different body type with the Pentax KP being a Mid-size SLR camera and the Pentax RS1500 being a Compact camera.

Before delving in to a detailed comparison, below is a short summary of how the KP matches up vs the RS1500 with regard to portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Pentax KP and Pentax Optio RS1500. The complete galleries are provided at Pentax KP Gallery and Pentax RS1500 Gallery.

If you are going to lug around your camera often, you need to take into account its weight and dimensions.

Do not forget, the weight of an Interchangeable Lens Camera will change based on the lens you select at the time. Underneath is the front view overall size comparison of the KP against the RS1500.

Taking into account size and weight, the portability grade of the KP and RS1500 is 61 and 93 respectively.

Oftentimes, it is very difficult to envision the gap between sensor measurements just by looking at a spec sheet. The graphic below may give you a better sense of the sensor sizing in the KP and RS1500.

As you can see, both of the cameras posses different megapixel count and different sensor measurements. The KP due to its larger sensor will make achieving shallower DOF less difficult and the Pentax KP will resolve greater detail as a result of its extra 10 Megapixels. Greater resolution will make it easier to crop images somewhat more aggressively. The more modern KP will have an advantage in sensor technology.
