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

Polaroid Snap: 81.2 x 25.4mm
3. focus points
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.
Sony Alpha a7 III: 693
4. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
5. maximum light sensitivity
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.
Nikon D7500 + Nikon AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR: 1640000 ISO
6. longer battery life
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Nikon D3x: 4400shots
7. video recording
1080 x 30fps
Canon EOS 1D X Mark II: 2160 x 60fps
HTC Re: 65.5g
9. fastest shutter speed
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
Sony Cyber-shot DSC-RX100 IV: 1/32000s
10. has a built-in HDR mode
It can automatically shoot pictures with a higher dynamic range (HDR).

11. has built-in optical image stabilization
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.

12. has AF tracking
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.

13. has a 24p cinema mode
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo.

19. has sensor shift stabilization
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.

20. has continuous autofocus when recording movies
When recording movies they stay focussed and sharp.

21. screen size
The bigger the screen size is, the better the user experience.
Samsung Galaxy Camera 2: 4.8"
22. can be controlled remotely
A remote control allows you to control the device remotely. The remote control can be included or optional.

23. has an optical viewfinder
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.

24. Is a system camera
A system camera has lots of changeable parts such as lenses, flashes and other accessories. They offer greater flexibility than compact cameras.
