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. 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.

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
6. video recording
1080 x 30fps
Canon EOS 1D X Mark II: 2160 x 60fps
HTC Re: 65.5g
8. 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
9. Is dustproof and water resistant
Dustproof/water resistant at depth equal to or greater than 1 meter.

10. 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.

DxO One: 26.2mm
12. Has timelapse function
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.

22. has a BSI sensor
A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.

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

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. 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.
