The PEN-F was unveiled 14 months earlier than the A9 which makes the cameras a generation apart from one another. Each of these cameras come with different body type with the Olympus PEN-F being a Rangefinder-style mirrorless camera and the Sony A9 being a SLR-style mirrorless camera.

Before delving in to a comprehensive comparison, below is a brief introduction of how the PEN-F scores against the A9 in relation to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Olympus PEN-F and Sony Alpha A9. The full galleries are viewable at Olympus PEN-F Gallery and Sony A9 Gallery.

For anyone who is going to lug around your camera frequently, you're going to have to factor in its weight and measurements.

Typically, it is very difficult to visualise the difference in sensor measurements merely by going through a spec sheet. The visual here will help give you a better sense of the sensor sizing in the PEN-F and A9.

As you can see, both the cameras posses different resolutions and different sensor measurements. The PEN-F with its smaller sensor will make achieving shallower depth of field tougher and the Sony A9 will show extra detail having an extra 4 Megapixels. Higher resolution can also let you crop photographs somewhat more aggressively. The older PEN-F will be behind when it comes to sensor innovation.
