Panasonic S1 vs Pentax K-70

On this page, we are evaluating the Panasonic S1 vs Pentax K-70, one being a Pro Mirrorless and the other is a Entry-Level DSLR by competitors Panasonic and Pentax. The resolution of the S1 (24MP) and the K-70 (24MP) is fairly well matched but the S1 (Full frame) and K-70 (APS-C) boast totally different sensor measurements.

The S1 was launched 2 years later than the K-70 and that is quite a serious gap as far as technology is concerned. The two cameras have different body design with the Panasonic S1 being a SLR-style mirrorless camera and the Pentax K-70 being a Compact SLR camera.

Before getting straight to a detailed comparison, here is a concise summation of how the S1 grades vs the K-70 when it comes to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Panasonic Lumix DC-S1 and Pentax K-70. The complete galleries are viewable at Panasonic S1 Gallery and Pentax K-70 Gallery.

For anyone who is aiming to lug around your camera, you will need to factor in its weight and proportions.

Don't forget, the weight of an Interchangeable Lens Camera will vary dependant on the lens you have attached at that moment. Here is a front view measurement comparison of the S1 versus the K-70.

Typically, it can be difficult to visualise the gap between sensor measurements purely by checking a spec sheet. The photograph here should give you a far better sense of the sensor sizes in the S1 and K-70.

As you can see, the 2 cameras provide the same megapixels but not the same sensor measurements. The S1 offers the larger sensor which should make getting shallow DOF less difficult. The more modern S1 is going to have an edge in sensor innovation.
