Common Weaknesses of Sony Alpha A7R III and Olympus Stylus 1s
Sony A7R III vs Olympus 1s: 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 A7R III and Olympus 1s side-by-side from the front, back and top in their relative dimensions. Sony A7R III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 657 g (1.45 lb / 23.17 oz) (including batteries). Olympus 1s 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 A7R III and Olympus 1s. Olympus 1s is clearly the smaller of the two cameras. Its body is 11mm narrower, 9mm shorter and 17mm thinner than Sony A7R III. As you can tell, actually this is not a fair size comparison since Olympus 1s has a built-in lens but Sony A7R III doesn't. Once you put a lens on A7R III, its thickness will increase significantly.

Here is the back view size comparison of Sony A7R III and Olympus 1s.

Now lets look at the top view comparison of Sony A7R III and Olympus 1s.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus 1s is significantly lighter (255g ) than the Sony A7R III 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 A7R III, the total kit will weigh much higher.

Weather Sealing

With its weather sealed body, we believe that A7R III has a big advantage over 1s which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7R III and Olympus 1s's LCD screens has the same diagonal size of 3.00".

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 A7R III vs Olympus 1s: Sensor Comparison

Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Olympus 1s has a 12.0MP 1/1.7' (7.44 x 5.58 mm ) sized BSI-CMOS sensor .

Sony A7R III's sensor provides 30MP more than Olympus 1s's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Another difference between these two cameras is that Sony A7R III's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Below you can see the A7R III and 1s sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7R III and Olympus 1s Cameras


As seen above, Sony A7R III has a 20.8x Larger sensor area than Olympus 1s. 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.
