Design

1.Has a flip-out screen
Sony a7S III
Sony Alpha a7 III
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Sony a7S III
Sony Alpha a7 III
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.Has a built-in focus motor
Sony a7S III
Sony Alpha a7 III
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
4.weight

699g

650g

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.
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.
6.has an optical viewfinder
Sony a7S III
Sony Alpha a7 III
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens will capture. OVFs have no time lag and require no power - as opposed to electronic viewfinders, which can drain battery life. OVFs are also better in low light situations.
7.Has a hot shoe
Sony a7S III
Sony Alpha a7 III
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
8.screen resolution

1440k dots

921.6k dots

A higher screen resolution provides a sharper image, making it easier to review your photos.
9.is a system camera
Sony a7S III
Sony Alpha a7 III
A system camera has many interchangeable components such as lenses, flashes, and other accessories. System cameras offer greater flexibility than compact cameras.

Optics

1.sensor size

35.6 x 23.8mm

35.8 x 23.8mm

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

409600 ISO

204800 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.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Sony a7S III
Sony Alpha a7 III
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
7.has built-in optical image stabilization
Sony a7S III
Sony Alpha a7 III
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
8.Has phase-detection autofocus for photos
Sony a7S III
Sony Alpha a7 III
Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.

Videography

1.video recording (main camera)

2160 x 120fps

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
Sony a7S III
Sony Alpha a7 III
A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
3.has continuous autofocus when recording movies
Sony a7S III
Sony Alpha a7 III
When recording movies they stay focussed and sharp.
4.Has timelapse function
Sony a7S III
Sony Alpha a7 III
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
5.has a 24p cinema mode
Sony a7S III
Sony Alpha a7 III
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
6.supports slow-motion video recording
Sony a7S III
Sony Alpha a7 III
Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Depending on camera capabilities, frame rates for slow-motion videos vary between 60fps and 960fps.
7.supports AVCHD format
Sony a7S III
Sony Alpha a7 III
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It's a standard popular among professional cameras and camcorders.
