The Efina was revealed 6 years after the K100D which is quite a big gap as far as technology is concerned. The two cameras offer different body type with the Pentax Efina being a Ultracompact camera and the Pentax K100D being a Compact SLR camera.

Before we go through a thorough comparison, below is a concise overview of how the Efina matches up against the K100D with respect to portability, imaging, features and an overall mark.

Here is a sample of the gallery pics for Pentax Efina and Pentax K100D. The full galleries are viewable at Pentax Efina Gallery and Pentax K100D Gallery.

For those who are going to travel with your camera often, you need to factor its weight and measurements.

Always remember, the weight of an Interchangeable Lens Camera will vary based on the lens you have chosen at that time. Underneath is the front view dimension comparison of the Efina compared to the K100D.

Looking at dimensions and weight, the portability rating of the Efina and K100D is 97 and 64 respectively.

Quite often, it is tough to envision the gap between sensor dimensions simply by looking at specifications. The pic here will help provide you a greater sense of the sensor sizing in the Efina and K100D.

Plainly, the two cameras offer different resolutions and different sensor dimensions. The Efina using its tinier sensor will make shooting bokeh tougher and the Pentax Efina will resolve greater detail because of its extra 8MP. Greater resolution can also make it easier to crop photos a little more aggressively. The fresher Efina will have an advantage when it comes to sensor technology.
