Olympus 550WP vs Pentax K-01

Let's look a little more closely at the Olympus 550WP versus Pentax K-01, one being a Small Sensor Compact and the other is a Entry-Level Mirrorless by competitors Olympus and Pentax. There is a significant difference between the sensor resolutions of the 550WP (10MP) and K-01 (16MP) and the 550WP (1/2.3") and K-01 (APS-C) feature totally different sensor measurements.

The 550WP was brought out 4 years before the K-01 and that is quite a sizable gap as far as tech is concerned. The two cameras offer different body type with the Olympus 550WP being a Compact camera and the Pentax K-01 being a SLR-style mirrorless camera.

Before diving through a comprehensive comparison, below is a brief synopsis of how the 550WP scores versus the K-01 with regard to portability, imaging, features and an overall rating.

Following is a sample of the gallery pics for Olympus Stylus 550WP and Pentax K-01. The entire galleries are viewable at Olympus 550WP Gallery and Pentax K-01 Gallery.

For those who are intending to carry your camera often, you'll need to consider its weight and measurements. The Olympus 550WP has got external measurements of 94mm x 62mm x 22mm (3.7" x 2.4" x 0.9") along with a weight of 167 grams (0.37 lbs) and the Pentax K-01 has proportions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") with a weight of 561 grams (1.24 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will vary based on the lens you choose at the time. The following is the front view sizing comparison of the 550WP against the K-01.

Considering size and weight, the portability grade of the 550WP and K-01 is 94 and 76 respectively.

Often, it is very hard to visualise the difference between sensor sizing purely by reading through a spec sheet. The visual here will help provide you a better sense of the sensor measurements in the 550WP and K-01.

As you can see, both of those cameras enjoy different megapixel count and different sensor sizing. The 550WP because of its tinier sensor will make shooting bokeh more difficult and the Pentax K-01 will resolve more detail having its extra 6MP. Greater resolution can also help you crop pics far more aggressively. The older 550WP is going to be disadvantaged in sensor tech.
