Sony Alpha 7S: 3702ISO
5. 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.

6. 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
8. video recording
720 x 30fps
Canon EOS 1D X Mark II: 2160 x 60fps
9. fastest shutter speed
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.

12. 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.
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.

19. Can create panoramas in-camera
It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo.

20. has sensor shift stabilization
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.

21. screen size
The bigger the screen size is, the better the user experience.

22. 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.

23. 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.

24. shutter lag
The amount of time it takes the camera to take a photo, without having to focus.

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