The E-620 was brought out 5 years prior to the K-3 and that is a fairly large gap as far as camera technology is concerned. Each of these cameras offer different body type with the Olympus E-620 being a Compact SLR camera and the Pentax K-3 being a Mid-size SLR camera.

Before getting straight into a thorough comparison, below is a short summation of how the E-620 grades versus the K-3 for portability, imaging, features and an overall grade.

Take into consideration, the weight of an Interchangeable Lens Camera will differ depending on the lens you have chosen at the time. Underneath is the front view dimension comparison of the E-620 and the K-3.

Factoring in dimensions and weight, the portability grade of the E-620 and K-3 is 71 and 59 respectively.

Typically, it's difficult to visualize the contrast in sensor measurements merely by seeing specifications. The photograph here will offer you a stronger sense of the sensor measurements in the E-620 and K-3.

To sum up, both of these cameras offer different resolutions and different sensor measurements. The E-620 due to its smaller sensor is going to make achieving shallow depth of field more difficult and the Pentax K-3 will produce extra detail having its extra 12 Megapixels. Higher resolution will make it easier to crop shots a little more aggressively. The older E-620 will be behind when it comes to sensor innovation.
