4.weight

580g

657g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
5.viewfinder coverage

100%

100%

With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.

Optics

1.sensor size

17.4 x 13mm

35.9 x 24mm

The larger the sensor the more light the sensor captures yielding in better image quality.
2.focus points

121

399

The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
3.megapixels (main camera)

21.8MP

42.4MP

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
4.maximum light sensitivity

25600 ISO

102400 ISO

With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
5.continuous shooting at high resolution

60fps

10fps

Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Olympus OM-D E-M1 Mark III
Sony Alpha a7R III

Videography

1.video recording (main camera)

2160 x 30fps

2160 x 30fps

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
2.Has phase-detection autofocus for videos
