The Reflex System

The Reflex System

What you see through the view finder is what the sensor is going to register.  These cameras allow you to use different lenses without a problem and work through a 45 degrees mirror a pentaprism a and a viewfinder. 

The Mirror

The mirror is situated to 45 degrees and is just in front of the shutter. It reflects the diverts the ray of light to the pentaprism a so you can see the scene through the viewfinder. When you take a photo it moves, letting the light pass by to the sensor. It goes back to its natural position when the shutter is closed. 

The Pentaprisma

It is a system of mirrors in the shape of a prism which is situated in the top of the camera. It inverts the image and proects it throughout the view finder. 

The view finder

It is in the back side of the camera and looking through it you can visualize the scene that will be captured.
