The Efina was released 3 years after the NEX-5 which is quite a significant difference as far as technology is concerned. The two cameras offer different body type with the Pentax Efina being a Ultracompact camera and the Sony NEX-5 being a Rangefinder-style mirrorless camera.

Before going straight into a step-by-step comparison, below is a short summary of how the Efina scores vs the NEX-5 in relation to portability, imaging, features and an overall score.
