The A9 was launched 3 years prior to the A6600 and that is quite a serious difference as far as technology is concerned. Both cameras offer different body type with the Sony A9 being a SLR-style mirrorless camera and the Sony A6600 being a Rangefinder-style mirrorless camera.

Before we go straight into a complete comparison, below is a short overview of how the A9 grades versus the A6600 with regard to portability, imaging, features and an overall grade.

Typically, it is very tough to visualise the gap between sensor measurements just by looking at technical specs. The visual underneath may give you a much better sense of the sensor measurements in the A9 and A6600.

As you can tell, the 2 cameras offer the same exact megapixel count albeit not the same sensor measurements. The A9 offers the bigger sensor which should make getting shallower DOF easier. The older A9 is going to be disadvantaged when it comes to sensor tech.
