Pentax K-01 vs Sigma fp L

In this article, we are looking at the Pentax K-01 and Sigma fp L, one is a Entry-Level Mirrorless and the other is a Advanced Mirrorless by manufacturers Pentax and Sigma. There exists a big gap among the sensor resolutions of the K-01 (16MP) and fp L (61MP) and the K-01 (APS-C) and fp L (Full frame) come with different sensor sizes.

The K-01 was introduced 9 years earlier than the fp L which is a fairly big gap as far as camera technology is concerned. Both cameras offer different body type with the Pentax K-01 being a SLR-style mirrorless camera and the Sigma fp L being a Rangefinder-style mirrorless camera.

Before getting straight into a thorough comparison, below is a quick highlight of how the K-01 scores versus the fp L in the way of portability, imaging, features and an overall score.

If you're going to carry around your camera frequently, you'll need to consider its weight and dimensions. The Pentax K-01 enjoys outer dimensions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") and a weight of 561 grams (1.24 lbs) whilst the Sigma fp L has dimensions of 113mm x 70mm x 45mm (4.4" x 2.8" x 1.8") along with a weight of 427 grams (0.94 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will change dependant on the lens you use at that moment. The following is the front view sizing comparison of the K-01 against the fp L.

Using dimensions and weight, the portability grade of the K-01 and fp L is 76 and 83 respectively.

Sometimes, it's difficult to picture the difference in sensor sizes simply by going through specs. The pic below may give you a stronger sense of the sensor dimensions in the K-01 and fp L.

All in all, both the cameras offer different resolutions and different sensor sizes. The K-01 using its smaller sensor is going to make achieving shallower DOF more challenging and the Sigma fp L will produce more detail using its extra 45 Megapixels. Greater resolution will enable you to crop pics a little more aggressively. The more aged K-01 will be behind in sensor tech.
