Olympus E-3 vs Pentax K-01

Let's examine more in depth at the Olympus E-3 and Pentax K-01, one is a Advanced DSLR and the latter is a Entry-Level Mirrorless by competitors Olympus and Pentax. There exists a crucial gap among the resolutions of the E-3 (10MP) and K-01 (16MP) and the E-3 (Four Thirds) and K-01 (APS-C) enjoy different sensor size.

The E-3 was introduced 5 years earlier than the K-01 which is a fairly serious gap as far as camera technology is concerned. Both of the cameras come with different body type with the Olympus E-3 being a Mid-size SLR camera and the Pentax K-01 being a SLR-style mirrorless camera.

Before getting straight into a complete comparison, below is a short overview of how the E-3 matches up against the K-01 when considering portability, imaging, features and an overall mark.

Here is a preview of the gallery images for Olympus E-3 and Pentax K-01. The whole galleries are viewable at Olympus E-3 Gallery and Pentax K-01 Gallery.

For anybody who is going to travel with your camera frequently, you need to factor its weight and proportions.

Quite often, it is tough to imagine the gap in sensor dimensions simply by viewing specifications. The image here may offer you a far better sense of the sensor measurements in the E-3 and K-01.

Plainly, both of those cameras posses different megapixel count and different sensor dimensions. The E-3 with its smaller sensor is going to make getting shallower DOF tougher and the Pentax K-01 will provide you with extra detail using its extra 6MP. Higher resolution will enable you to crop shots somewhat more aggressively. The more aged E-3 will be disadvantaged in sensor technology.
