These are just a few:
-Aperture (it helps the user control the amount of light the camera is shining through”
-Battery Duration (helps the user use the camera for long periods of time)
-Zoom Lens (helps zoom in or zoom out certain things you’re taking pictures of)
-Image Stabilization (prevents your picture from being blurry and not turning out well; this might result in a camera shake or when movement is detected while taking it)
