The Efina was brought out 15 months prior to the QX1 which makes them a generation apart from each other. Each of the cameras feature different body design with the Pentax Efina being a Ultracompact camera and the Sony QX1 being a Lens-style camera.

Before getting right into a in depth comparison, here is a brief highlight of how the Efina scores vs the QX1 in the way of portability, imaging, features and an overall grade.

Following is a preview of the gallery photos for Pentax Efina and Sony Alpha QX1. The entire galleries are available at Pentax Efina Gallery and Sony QX1 Gallery.

In case you're looking to lug around your camera, you will have to factor in its weight and dimensions. The Pentax Efina features outer measurements of 87mm x 54mm x 21mm (3.4" x 2.1" x 0.8") accompanied by a weight of 91 grams (0.20 lbs) while the Sony QX1 has dimensions of 74mm x 70mm x 53mm (2.9" x 2.8" x 2.1") and a weight of 216 grams (0.48 lbs).

Generally, it is very difficult to envision the difference between sensor measurements purely by looking at technical specs. The photograph below will help offer you a stronger sense of the sensor measurements in the Efina and QX1.

As you can tell, both the cameras feature different resolutions and different sensor measurements. The Efina featuring a tinier sensor will make getting shallow depth of field trickier and the Sony QX1 will give greater detail having its extra 6MP. Higher resolution will also enable you to crop pictures way more aggressively. The older Efina is going to be disadvantaged in sensor innovation.
