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.
Canon EOS R: 5655
4. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.

Sony Alpha a7 III: 3730ISO
6. 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
7. 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
8. image quality
A device's overall image quality score considers: color depth, dynamic range and low light performance. Source: DxOMark.
Sony Alpha 7R II: 98
HTC Re: 65.5g
10. 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
11. color depth
The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
HP Photosmart R927: 42bits
12. Has phase detection autofocus for photos
A phase detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

13. dynamic range
The better the dynamic range the system captures a wider number of values from dark to light leading to more details in low and highlights. Source: DxOMark.
A two-stage shutter is good for taking photos like a pro; apply pressure to the button in order for the lens to focus, and then press it fully to capture the photograph.

22. shoots raw
A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

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.

25. 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.
