The G9 was revealed 3 years later than the A7R and that is a fairly large gap as far as camera technology is concerned. Both cameras offer the identical body type (SLR-style mirrorless).

Before getting straight into a full comparison, below is a short synopsis of how the G9 scores against the A7R in regards to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Panasonic Lumix DC-G9 and Sony Alpha A7R. The full galleries are available at Panasonic G9 Gallery and Sony A7R Gallery.

If you're looking to carry your camera often, you have to factor in its weight and volume.

Quite often, it is very hard to visualise the difference in sensor sizing simply by checking out technical specs. The visual below will offer you a stronger sense of the sensor sizing in the G9 and A7R.

As you have seen, each of the cameras offer different megapixel count and different sensor sizing. The G9 with its smaller sensor will make getting shallower DOF more challenging and the Sony A7R will produce extra detail because of its extra 16MP. Greater resolution will also let you crop pics a little more aggressively. The newer G9 is going to have an advantage when it comes to sensor tech.
