Sony A7S vs Sony NEX-7

Lets look more closely at the Sony A7S and Sony NEX-7, one being a Pro Mirrorless and the other is a Advanced Mirrorless and both of them are created by Sony. There exists a crucial gap among the resolutions of the A7S (12MP) and NEX-7 (24MP) and the A7S (Full frame) and NEX-7 (APS-C) enjoy different sensor size.

The A7S was revealed 2 years later than the NEX-7 and that is a fairly serious gap as far as camera technology is concerned. Both of these cameras come with different body type with the Sony A7S being a SLR-style mirrorless camera and the Sony NEX-7 being a Rangefinder-style mirrorless camera.

Before diving through a in-depth comparison, below is a simple overview of how the A7S grades vs the NEX-7 in terms of portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Sony Alpha A7S and Sony Alpha NEX-7. The full galleries are viewable at Sony A7S Gallery and Sony NEX-7 Gallery.

For those who are going to carry your camera regularly, you need to factor its weight and measurements. The Sony A7S has outside dimensions of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") with a weight of 489 grams (1.08 lbs) and the Sony NEX-7 has proportions of 120mm x 67mm x 43mm (4.7" x 2.6" x 1.7") along with a weight of 400 grams (0.88 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary depending on the lens you have chosen at that time. Here is the front view overall size comparison of the A7S vs the NEX-7.

Looking at dimensions and weight, the portability grade of the A7S and NEX-7 is 77 and 84 respectively.

Quite often, its difficult to visualize the gap in sensor sizing purely by going through specifications. The photograph here should offer you a better sense of the sensor dimensions in the A7S and NEX-7.

Plainly, the two cameras posses different megapixel count and different sensor sizing. The A7S having a larger sensor is going to make achieving shallow depth of field easier and the Sony NEX-7 will provide more detail because of its extra 12MP. Greater resolution can also allow you to crop photos somewhat more aggressively. The younger A7S should have a benefit when it comes to sensor tech.
