The larger the sensor the more light the sensor captures yielding in better image quality.
23.5 x 15.6mm
Polaroid Snap: 81.2 x 38mm
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 a6500: 425
4. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
5. has a flip-out screen
Flip-out screens are useful for doing tricky shots.
A higher screen resolution provides a sharper image, making it easier to review your photos.

20. 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.
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.
With 100% coverage you can compose the image correctly when you capture the photo. With less than full coverage you may have to crop your photos afterwards to get them looking perfect.
Sony Alpha 7R: 100%
32. 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.
