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. 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
4. 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
5. video recording (main camera)
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.
1280 x 30fps
Fujifilm X-T3: 2160 x 60fps
HTC Re: 65.5g
7. 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
8. 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.

9. 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.
It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo.

24. 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.
Nikon Coolpix P1000: 125x
25. widest aperture
With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
