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 E-1 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 E-1 has external dimensions of 141 x 104 x 81 mm (5.55 x 4.09 x 3.19″) and weighs 735 g (1.62 lb / 25.93 oz) (including batteries).
Below you can see the front view size comparison of Sony A7R III and Olympus E-1. Sony A7R III is clearly the smaller of the two cameras. Its body is 14mm narrower, 8mm shorter and 7mm thinner than Olympus E-1.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A7R III is 78g lighter than the Olympus E-1 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Sony A7R III has a Full frame sensor and Olympus E-1 has a smaller Four Thirds sensor, Olympus E-1's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7R III lenses.

Weather Sealing
Both A7R III and E-1 have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Sony A7R III's 3 LCD screen is slightly larger than Olympus E-1's 1.8" screen.
In addition to the size advantage, Sony A7R III LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Olympus E-1 has a fixed type screen which provides less flexibility in shooting positions compared to A7R III.
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 E-1 has a 5.0MP Four Thirds (17.3 x 13 mm ) sized CCD sensor .
Sony A7R III's sensor provides 37MP more than Olympus E-1'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 E-1 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7R III and Olympus E-1 Cameras
As seen above, Sony A7R III has a 3.8x Larger sensor area than Olympus E-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.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Sony A7R III has an advantage over Olympus E-1. There are 128 lenses for Sony A7R III's Sony E mount, on the other hand there are only 45 lenses for Olympus E-1's Four Thirds lens mount.
Another important factor is the availability of image stabilization. Sony A7R III has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. A7R III's built-in Image stabilization system is effective to compensate vibration up to 5.0-stops according to CIPA standards.3 lenses for Four Thirds mount with Optical Image Stabilization features.
