The larger the sensor the more light the sensor captures yielding in better image quality.
6.17 x 4.55mm
Polaroid Snap: 81.2 x 25.4mm
3. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
4. 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
5. 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
HTC Re: 65.5g
7. video recording
1080 x 30fps
Canon EOS 1D X Mark II: 2160 x 60fps
8. Has WiFi
The device can connect to WiFi.

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. has a built-in HDR mode
It can automatically shoot pictures with a higher dynamic range (HDR).

DxO One: 26.2mm
13. 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.
It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo.

19. screen size
The bigger the screen size is, the better the user experience.
Samsung Galaxy Camera 2: 4.8"
20. has a two-stage shutter
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.

21. 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.

22. has a flash
A flash is good for low-light environments, and can sometimes be used as flashlight.

23. has a serial shot mode
You can shoot multiple pictures in a row.

24. has a CMOS sensor
CMOS image sensors are slowly replacing CCD sensors, due to reduced power consumption and better image quality. They can be very compact and cost relatively little to produce.

25. optical zoom
The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.
