Pentax K-01 vs Pentax W90

Its time to examine more closely at the Pentax K-01 vs Pentax W90, one is a Entry-Level Mirrorless and the latter is a Waterproof and both of them are built by Pentax. There exists a crucial gap between the image resolutions of the K-01 (16MP) and W90 (12MP) and the K-01 (APS-C) and W90 (1/2.3") use different sensor dimensions.

Photography Glossary

The K-01 was introduced 2 years after the W90 which is quite a serious gap as far as technology is concerned. Each of these cameras offer different body type with the Pentax K-01 being a SLR-style mirrorless camera and the Pentax W90 being a Compact camera.

Before we go in to a detailed comparison, below is a short view of how the K-01 grades versus the W90 in relation to portability, imaging, features and an overall score.

Here is a preview of the gallery images for Pentax K-01 and Pentax Optio W90. The whole galleries are provided at Pentax K-01 Gallery and Pentax W90 Gallery.

For anybody who is looking to carry around your camera, you'll have to factor its weight and volume. The Pentax K-01 features outside dimensions of 122mm x 79mm x 58mm (4.8" x 3.1" x 2.3") having a weight of 561 grams (1.24 lbs) whilst the Pentax W90 has sizing of 108mm x 59mm x 25mm (4.3" x 2.3" x 1.0") with a weight of 164 grams (0.36 lbs).

Look at the Pentax K-01 vs Pentax W90 in the new Camera with Lens Size Comparison Tool.

Take into account, the weight of an Interchangeable Lens Camera will change based on the lens you are utilizing at that time. Underneath is the front view physical size comparison of the K-01 against the W90.

Looking at dimensions and weight, the portability score of the K-01 and W90 is 76 and 94 respectively.

Normally, it is very hard to visualize the gap between sensor sizes purely by going over a spec sheet. The picture here should give you a more clear sense of the sensor dimensions in the K-01 and W90.

Clearly, each of these cameras enjoy different megapixel count and different sensor sizes. The K-01 having a bigger sensor is going to make shooting shallow DOF less difficult and the Pentax K-01 will offer extra detail using its extra 4MP. Higher resolution can also help you crop photographs far more aggressively. The more modern K-01 should have an advantage when it comes to sensor tech.
