Pentax K-1 vs Pentax RS1500

Let's take a deeper look at the Pentax K-1 and Pentax RS1500, former being a Advanced DSLR while the other is a Small Sensor Compact and both are sold by Pentax. There exists a substantial gap among the resolutions of the K-1 (36MP) and RS1500 (14MP) and the K-1 (Full frame) and RS1500 (1/2.3") provide different sensor measurements.

The K-1 was unveiled 4 years later than the RS1500 and that is a fairly big difference as far as camera technology is concerned. Both of these cameras have different body design with the Pentax K-1 being a Mid-size SLR camera and the Pentax RS1500 being a Compact camera.

Before diving straight to a in depth comparison, here is a quick summation of how the K-1 grades versus the RS1500 when it comes to portability, imaging, features and an overall grade.

In case you're going to lug around your camera frequently, you will want to think about its weight and proportions. The Pentax K-1 comes with external dimensions of 137mm x 110mm x 86mm (5.4" x 4.3" x 3.4") having a weight of 1010 grams (2.23 lbs) whilst the Pentax RS1500 has measurements of 114mm x 58mm x 28mm (4.5" x 2.3" x 1.1") accompanied by a weight of 157 grams (0.35 lbs).

Remember that, the weight of an ILC will vary based on the lens you are working with at the time. Underneath is a front view measurement comparison of the K-1 vs the RS1500.

Taking into account dimensions and weight, the portability score of the K-1 and RS1500 is 55 and 93 respectively.

Sometimes, it can be tough to imagine the contrast in sensor measurements purely by going through specs. The visual here may provide you a more clear sense of the sensor dimensions in the K-1 and RS1500.

All in all, both cameras have different megapixel count and different sensor measurements. The K-1 using its larger sensor is going to make achieving shallow depth of field easier and the Pentax K-1 will show more detail having an extra 22MP. Greater resolution will enable you to crop pics a bit more aggressively. The more modern K-1 provides an edge with regard to sensor technology.
