Panasonic G1 vs Sony A7S

Let's take a closer look at the Panasonic G1 and Sony A7S, former being a Entry-Level Mirrorless while the latter is a Pro Mirrorless by competitors Panasonic and Sony. The resolution of the G1 (12MP) and the A7S (12MP) is pretty close but the G1 (Four Thirds) and A7S (Full frame) boast different sensor sizes.

The G1 was unveiled 6 years earlier than the A7S and that is a fairly significant difference as far as camera technology is concerned. The two cameras feature the same body design (SLR-style mirrorless).

Before diving right into a in-depth comparison, here is a simple introduction of how the G1 grades against the A7S when considering portability, imaging, features and an overall grade.

Here is a preview of the gallery images for Panasonic Lumix DMC-G1 & Sony Alpha A7S. The full galleries are viewable at Panasonic G1 Gallery & Sony A7S Gallery.

If you are going to lug around your camera regularly, you're going to have to consider its weight and dimensions. The Panasonic G1 has external measurements of 124mm x 84mm x 45mm (4.9" x 3.3" x 1.8") and a weight of 360 grams (0.79 lbs) whilst the Sony A7S has dimensions of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") with a weight of 489 grams (1.08 lbs).

Take into consideration, the weight of an ILC will change based on the lens you use at that moment. Underneath is a front view dimensions comparison of the G1 vs the A7S.

Looking at dimensions and weight, the portability rating of the G1 and A7S is 82 and 77 respectively.

Normally, its difficult to imagine the difference in sensor measurements simply by viewing technical specs. The graphic underneath may give you a better sense of the sensor sizing in the G1 and A7S.

As you have seen, each of these cameras feature the identical megapixel count albeit different sensor measurements. The G1 has got the smaller sensor which should make achieving shallower DOF trickier. The older G1 will be behind with regard to sensor innovation.
