On this page, we will be looking at the Panasonic GH2 versus Sony A7S, former being a Advanced Mirrorless while the latter is a Pro Mirrorless by rivals Panasonic and Sony. There exists a considerable gap among the resolutions of the GH2 (16MP) and A7S (12MP) and the GH2 (Four Thirds) and A7S (Full frame) boast different sensor measurements.

The GH2 was revealed 4 years earlier than the A7S and that is a fairly large difference as far as camera technology is concerned. Both cameras have the same body design (SLR-style mirrorless).

Before going into a comprehensive comparison, here is a quick introduction of how the GH2 grades against the A7S in relation to portability, imaging, features and an overall rating.

Following is a preview of the gallery images for Panasonic Lumix DMC-GH2 & Sony Alpha A7S. The full galleries are available at Panasonic GH2 Gallery & Sony A7S Gallery.

When you are looking to carry your camera regularly, you have to factor in its weight and proportions. The Panasonic GH2 enjoys outer dimensions of 124mm x 90mm x 76mm (4.9" x 3.5" x 3.0") having a weight of 442 grams (0.97 lbs) whilst the Sony A7S has measurements of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") having a weight of 489 grams (1.08 lbs).

Bear in mind, the weight of an ILC will differ based on the lens you have during that time. Below is a front view dimension comparison of the GH2 against the A7S.

Taking into consideration dimensions and weight, the portability score of the GH2 and A7S is 70 and 77 respectively.

Quite often, it's hard to visualize the gap in sensor sizing simply by checking out a spec sheet. The graphic below might give you a more clear sense of the sensor dimensions in the GH2 and A7S.

Clearly, the two cameras provide different resolutions and different sensor sizing. The GH2 with its smaller sensor is going to make achieving shallow depth of field trickier and the Panasonic GH2 will show greater detail because of its extra 4 Megapixels. Higher resolution can also allow you to crop pictures more aggressively. The older GH2 will be behind when it comes to sensor tech.
