Olympus PEN-F vs Sony A850 Sensor Comparison

Generally, it can be tough to visualise the difference in sensor dimensions merely by seeing a spec sheet. The image underneath may give you a far better sense of the sensor measurements in the PEN-F and A850.

As you can see, both of the cameras offer different resolutions and different sensor dimensions. The PEN-F having a smaller sensor will make getting shallower DOF more challenging and the Sony A850 will provide extra detail with its extra 5 Megapixels. Greater resolution will also allow you to crop photos a little more aggressively. The fresher PEN-F is going to have a benefit with regard to sensor innovation.
