Pentax K-01 vs Sony A7S

Let's look more closely at the Pentax K-01 and Sony A7S, one being a Entry-Level Mirrorless and the other is a Pro Mirrorless by manufacturers Pentax and Sony. There exists a big gap between the sensor resolutions of the K-01 (16MP) and A7S (12MP) and the K-01 (APS-C) and A7S (Full frame) offer different sensor size.

The K-01 was launched 22 months prior to the A7S making them a generation apart from one another. Both of these cameras feature the same body design (SLR-style mirrorless).

Before delving into a thorough comparison, here is a short synopsis of how the K-01 scores vs the A7S in relation to portability, imaging, features and an overall grade.

This is a sample of the gallery pics for Pentax K-01 and Sony Alpha A7S. The complete galleries are provided at Pentax K-01 Gallery and Sony A7S Gallery.

When you are looking to lug around your camera, you're going to have to think about its weight and measurements. The Pentax K-01 comes with exterior measurements of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") accompanied by a weight of 561 grams (1.24 lbs) while the Sony A7S has proportions of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") accompanied by a weight of 489 grams (1.08 lbs).

Take into account, the weight of an Interchangeable Lens Camera will differ depending on the lens you use during that time. The following is a front view dimension comparison of the K-01 vs the A7S.

Quite often, it is very difficult to picture the contrast between sensor measurements simply by going over a spec sheet. The photograph here may offer you a greater sense of the sensor measurements in the K-01 and A7S.

As you can see, both the cameras feature different resolutions and different sensor measurements. The K-01 featuring a tinier sensor is going to make getting bokeh trickier and the Pentax K-01 will deliver greater detail utilizing its extra 4MP. Greater resolution will let you crop photos way more aggressively. The older K-01 is going to be behind with regard to sensor tech.
