Olympus FE-4000 vs Pentax K-01

In this write-up, we will be reviewing the Olympus FE-4000 versus Pentax K-01, one is a Small Sensor Compact and the latter is a Entry-Level Mirrorless by competitors Olympus and Pentax. There exists a significant gap between the image resolutions of the FE-4000 (12MP) and K-01 (16MP) and the FE-4000 (1/2.3") and K-01 (APS-C) possess totally different sensor measurements.

The FE-4000 was launched 3 years before the K-01 which is quite a sizable gap as far as technology is concerned. Both of the cameras offer different body type with the Olympus FE-4000 being a Compact camera and the Pentax K-01 being a SLR-style mirrorless camera.

Before we go in to a in depth comparison, below is a quick highlight of how the FE-4000 grades vs the K-01 when it comes to portability, imaging, features and an overall score.

Here is a preview of the gallery photos for Olympus FE-4000 and Pentax K-01. The complete galleries are available at Olympus FE-4000 Gallery and Pentax K-01 Gallery.

If you're looking to carry around your camera, you should factor in its weight and measurements. The Olympus FE-4000 enjoys outer dimensions of 95mm x 57mm x 22mm (3.7" x 2.2" x 0.9") having a weight of 136 grams (0.30 lbs) whilst the Pentax K-01 has proportions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") having a weight of 561 grams (1.24 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have at the time. Here is the front view dimensions comparison of the FE-4000 versus the K-01.

Looking at dimensions and weight, the portability grade of the FE-4000 and K-01 is 95 and 76 respectively.

More often than not, its difficult to envision the gap between sensor sizes just by reading through specifications. The image below may provide you a more clear sense of the sensor sizes in the FE-4000 and K-01.

Plainly, both of those cameras enjoy different megapixel count and different sensor sizes. The FE-4000 because of its tinier sensor will make achieving shallow DOF tougher and the Pentax K-01 will resolve extra detail utilizing its extra 4 Megapixels. Higher resolution will allow you to crop pictures far more aggressively. The more aged FE-4000 is going to be disadvantaged when it comes to sensor tech.
