Sony A7S III vs Sony NEX-3N

Let's look more closely at the Sony A7S III vs Sony NEX-3N, one being a Pro Mirrorless and the other is a Entry-Level Mirrorless and both of them are produced by Sony. There exists a big gap between the resolutions of the A7S III (12MP) and NEX-3N (16MP) and the A7S III (Full frame) and NEX-3N (APS-C) provide totally different sensor dimensions.

The A7S III was introduced 7 years later than the NEX-3N and that is quite a big gap as far as technology is concerned. The two cameras feature different body design with the Sony A7S III being a SLR-style mirrorless camera and the Sony NEX-3N being a Rangefinder-style mirrorless camera.

Before we go right into a more detailed comparison, here is a brief summary of how the A7S III scores vs the NEX-3N in terms of portability, imaging, features and an overall rating.

Here is a sample of the gallery pics for Sony Alpha A7S III and Sony Alpha NEX-3N. The whole galleries are viewable at Sony A7S III Gallery and Sony NEX-3N Gallery.

In case you're looking to carry your camera regularly, you will have to think about its weight and proportions.

Don't forget, the weight of an Interchangeable Lens Camera will vary dependant on the lens you have chosen during that time. Underneath is a front view dimensions comparison of the A7S III vs the NEX-3N.

Using dimensions and weight, the portability score of the A7S III and NEX-3N is 61 and 89 respectively.

More often than not, it can be hard to visualise the contrast between sensor sizing purely by reading through technical specs. The visual here should give you a stronger sense of the sensor measurements in the A7S III and NEX-3N.

As you have seen, both of these cameras feature different resolutions and different sensor sizing. The A7S III with its larger sensor will make shooting shallower depth of field easier and the Sony NEX-3N will give you greater detail using its extra 4 Megapixels. Greater resolution will also help you crop photos way more aggressively. The fresher A7S III is going to have an advantage when it comes to sensor tech.
