Olympus FE-45 vs Pentax K-3

Below is a comprehensive overview of the Olympus FE-45 versus Pentax K-3, one being a Small Sensor Compact and the other is a Advanced DSLR by brands Olympus and Pentax. There is a big difference between the sensor resolutions of the FE-45 (10MP) and K-3 (24MP) and the FE-45 (1/2.3") and K-3 (APS-C) possess different sensor sizing.

The FE-45 was manufactured 6 years before the K-3 and that is quite a big gap as far as tech is concerned. Both of these cameras offer different body type with the Olympus FE-45 being a Compact camera and the Pentax K-3 being a Mid-size SLR camera.

Before going through a comprehensive comparison, below is a short summation of how the FE-45 grades versus the K-3 with respect to portability, imaging, features and an overall grade.

Often, it can be tough to picture the contrast between sensor measurements purely by reading through a spec sheet. The photograph below might give you a much better sense of the sensor sizes in the FE-45 and K-3.

Clearly, the 2 cameras enjoy different megapixel count and different sensor measurements. The FE-45 because of its tinier sensor is going to make achieving shallower DOF harder and the Pentax K-3 will give you extra detail due to its extra 14 Megapixels. Greater resolution will enable you to crop photos far more aggressively. The older FE-45 is going to be disadvantaged in sensor tech.
