Working principles of DSLR

• Through the prism, light enters the camera and hits the reflex mirror
• The reflex mirror vertically reflects the light upwards to the focusing screen
• Light passes via the focusing display and reaches the block of glass that is a pentaprism
• The pentaprism focuses the light via two different mirrors and then diverts it to the viewfinder
• The viewfinder offers viewers a live picture preview
• The reflex mirror now flips upwards after users press the button to capture an image and prevents the vertical path of light from holding it straight towards its image sensor
• The shutter will open and the light will enter the image sensor
