Pentax K-01 vs Pentax S1

Here, we will be analyzing the Pentax K-01 versus Pentax S1, former is a Entry-Level Mirrorless while the latter is a Small Sensor Compact and both of them are built by Pentax. The image resolution of the K-01 (16MP) and the S1 (14MP) is relatively comparable but the K-01 (APS-C) and S1 (1/2.3") provide different sensor measurements.

The K-01 was introduced 16 months after the S1 which makes them a generation away from each other. The two cameras feature different body design with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax S1 being a Compact camera.

Before going straight to a comprehensive comparison, here is a quick introduction of how the K-01 scores against the S1 with regard to portability, imaging, features and an overall score.

The following is a preview of the gallery photos for Pentax K-01 & Pentax Optio S1. The whole galleries are available at Pentax K-01 Gallery & Pentax S1 Gallery.

If you are planning to carry around your camera regularly, you should take into account its weight and volume. The Pentax K-01 features physical dimensions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") along with a weight of 561 grams (1.24 lbs) and the Pentax S1 has sizing of 114mm x 58mm x 28mm (4.5" x 2.3" x 1.1") and a weight of 157 grams (0.35 lbs).

Do not forget, the weight of an ILC will vary based on the lens you are utilising at that moment. Following is a front view dimensions comparison of the K-01 and the S1.

Taking into consideration size and weight, the portability score of the K-01 and S1 is 76 and 93 respectively.

Generally, its difficult to visualize the gap in sensor sizes purely by checking out specs. The image here should give you a stronger sense of the sensor dimensions in the K-01 and S1.

All in all, both of those cameras come with different resolutions and different sensor sizes. The K-01 with its bigger sensor is going to make getting shallower DOF easier and the Pentax K-01 will produce more detail using its extra 2MP. Higher resolution can also allow you to crop photographs a good deal more aggressively. The fresher K-01 provides an edge in sensor tech.
