Pentax K-01 vs Pentax S1

On this page, we are contrasting the Pentax K-01 vs Pentax S1, one is a Entry-Level Mirrorless and the other is a Small Sensor Compact and both are designed by Pentax. The image resolution of the K-01 (16MP) and the S1 (14MP) is very similar but the K-01 (APS-C) and S1 (1/2.3") offer different sensor measurements.

Photographer fined '$200,000' for failing to deliver photos

The K-01 was released 16 months after the S1 making them a generation away from one another. Both cameras have different body design with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax S1 being a Compact camera.

Before delving right into a more detailed comparison, here is a short synopsis of how the K-01 grades against the S1 for portability, imaging, features and an overall mark.

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.
