Sony A7S vs Olympus 1 Comparison Overview

Here we are comparing two cameras with different body types: Sony A7S, which was introduced in April 2014 is a Pro Mirrorless camera with a 12.0MP Full frame sensor whereas Olympus 1, which was introduced in November 2013 is a Small Sensor Superzoom camera with a 12.0MP 1/1.7" sensor. There is only 4 months difference between A7S and 1 so we are expecting this to be a fair comparison regarding age and technology level.

Comparing an interchangeble lens camera to a fixed lens camera is a bit tricky but we will do our best to make this a fair comparison.

Here is a brief look at the main features of Sony A7S and Olympus 1 before getting into our more detailed comparison.

Common Weaknesses of Sony Alpha A7S and Olympus Stylus 1
Sony A7S vs Olympus 1: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Sony A7S and Olympus 1 side-by-side from the front, back and top in their relative dimensions. Sony A7S has external dimensions of 127 x 94 x 48 mm (5 x 3.7 x 1.89″) and weighs 489 g (1.08 lb / 17.25 oz) (including batteries). Olympus 1 has external dimensions of 116 x 87 x 57 mm (4.57 x 3.43 x 2.24″) and weighs 402 g (0.89 lb / 14.18 oz) (including batteries).

Below you can see the front view size comparison of Sony A7S and Olympus 1. Olympus 1 is 11mm narrower and 7mm shorter than Sony A7S but it is also 9mm thicker. As you can tell, actually this is not a fair size comparison since Olympus 1 has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, its thickness will increase significantly.

Here is the back view size comparison of Sony A7S and Olympus 1.

Now lets look at the top view comparison of Sony A7S and Olympus 1.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus 1 is significantly lighter (87g ) than the Sony A7S which may become a big advantage especially on long walking trips.

Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on A7S, the total kit will weigh much higher.

Weather Sealing

With its weather sealed body, we believe that A7S has a big advantage over 1 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7S and Olympus 1's LCD screens has the same diagonal size of 3.

Both cameras feature Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over the head levels.
Sony A7S vs Olympus 1: Sensor Comparison

Both Sony A7S and Olympus 1 have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Olympus 1's sensor is 1/1.7" (7.44 x 5.58 mm ).

Since Sony A7S's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Olympus 1.

Below you can see the A7S and 1 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Olympus 1 Cameras


As seen above, Sony A7S has a 20.6x Larger sensor area than Olympus 1. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.

DxOMark Sensor Scores

Both Sony A7S and Olympus 1 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, A7S has scored 87, 36 points higher than 1.

Model Overall Color Depth Dynamic Range Low-light ISO
Sony A7S 87 23.9 bits 13.2 Evs 3702 ISO
Olympus 1 51 20.7 bits 11.6 Evs 179 ISO
