Olympus TG-4 vs Pentax K-01

Lets look more in depth at the Olympus TG-4 and Pentax K-01, one is a Waterproof and the other is a Entry-Level Mirrorless by manufacturers Olympus and Pentax. The sensor resolution of the TG-4 (16MP) and the K-01 (16MP) is very comparable but the TG-4 (1/2.3") and K-01 (APS-C) provide different sensor sizes.

The TG-4 was released 2 years after the K-01 which is a fairly significant gap as far as camera technology is concerned. Both of these cameras feature different body design with the Olympus TG-4 being a Compact camera and the Pentax K-01 being a SLR-style mirrorless camera.

Before going straight to a thorough comparison, here is a quick introduction of how the TG-4 scores versus the K-01 in terms of portability, imaging, features and an overall score.

Below is a sample of the gallery pics for Olympus Tough TG-4 and Pentax K-01. The complete galleries are available at Olympus TG-4 Gallery and Pentax K-01 Gallery.

For anyone who is going to carry around your camera frequently, you're going to have to think about its weight and proportions. The Olympus TG-4 provides outer measurements of 112mm x 66mm x 31mm (4.4" x 2.6" x 1.2") and a weight of 247 grams (0.54 lbs) whilst the Pentax K-01 has measurements 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 chosen at that time. Following is a front view size comparison of the TG-4 and the K-01.

Using dimensions and weight, the portability score of the TG-4 and K-01 is 90 and 76 respectively.

Typically, it can be difficult to visualize the difference in sensor sizes simply by going through specifications. The picture here may give you a more clear sense of the sensor measurements in the TG-4 and K-01.

Plainly, the two cameras come with the identical megapixels but different sensor sizes. The TG-4 contains the smaller sensor which should make obtaining bokeh more challenging. The fresher TG-4 should have a benefit in sensor tech.
