Pentax K-01 vs Pentax K-3 II

On this page, we will be comparing the Pentax K-01 versus Pentax K-3 II, former being a Entry-Level Mirrorless while the latter is a Advanced DSLR and both are built by Pentax. There exists a considerable gap between the sensor resolutions of the K-01 (16MP) and K-3 II (24MP) but both cameras have the same sensor sizing (APS-C).

Photography Glossary

The K-01 was brought out 3 years prior to the K-3 II and that is quite a large difference as far as technology is concerned. Both of these cameras have different body design with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax K-3 II being a Mid-size SLR camera.

Before getting straight to a in depth comparison, here is a concise highlight of how the K-01 matches up versus the K-3 II with regards to portability, imaging, features and an overall rating.

The following is a preview of the gallery photos for Pentax K-01 & Pentax K-3 II. The entire galleries are provided at Pentax K-01 Gallery & Pentax K-3 II Gallery.

If you are planning to carry your camera frequently, you're going to have to factor its weight and volume.

Bear in mind, the weight of an ILC will vary dependant on the lens you are using at that time. Here is a front view dimensions comparison of the K-01 versus the K-3 II.

Factoring in dimensions and weight, the portability grade of the K-01 and K-3 II is 76 and 59 respectively.

Quite often, it is hard to visualise the difference between sensor sizing just by reading a spec sheet. The visual below will help provide you a clearer sense of the sensor sizing in the K-01 and K-3 II.

Clearly, the 2 cameras have the same sensor dimensions albeit not the same MP. You can count on the Pentax K-3 II to offer more detail having its extra 8MP. Higher resolution will also help you crop shots a bit more aggressively. The older K-01 is going to be disadvantaged in sensor tech.
