The larger the sensor the more light the sensor captures yielding in better image quality.

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.

4. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.

5. has a flip-out screen
Flip-out screens are useful for doing tricky shots.
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.
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.
More microphones result in better sound quality and enable the device to filter out background noise.

34. 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.
