Having the choice of switching between electronic and mechanical provides greater flexibility in varying shooting conditions. Mirrorless digital cameras also feature an electronic shutter that replicates the actions of a mechanical shutter.
When you press the shutter button, the mirror flips out of the way, and the shutter opens up for a fraction of a second – long enough to expose the camera sensor to the light. The camera sensor sits behind this mirror/shutter combo – as a result, it blocks the light from the sensor. The reflected light passes into the optical viewfinder so you can see what’s in the frame. The light travels into the lens and bounces off a mirror inside the camera. When you look through a DSLR optical viewfinder, you see a true to life view of what the camera lens sees. Mechanical ShutterĭSLRs feature a mechanical shutter as they have a physical device that moves up and down to expose the camera sensor.īut there’s a lot more to it than that. There are two types of shutter that most current generation cameras possess – especially in the mirrorless arena. (It’s probably better to say how they go about exposing the sensor to light has improved over time.) With DSLR and mirrorless camera technology development, camera shutters have improved over time – but their primary function remains. The leaf shutter is the same size and sits directly behind this element – effectively blocking the light passing through the lens. With a fixed lens, the rear lens element is relatively small. It can be as small as the rear element of the lens, such as in the image above. This way, the leaf shutter does not have to be a significant device to cover the whole image sensor. Each of the diaphragm blades of a leaf shutter opens from the centre out.Ī focal plane shutter is positioned up against and almost touching the sensor, while a leaf shutter sits forward from the sensor up against the lens’s rear. Once the shutter speed duration has lapsed, they snap shut to block any further light spilling in. When you press the camera’s shutter button, the blades open to allow light to pass through. Located in front of the camera sensor, a leaf shutter has overlapping metal blades that close so no light passes through to the sensor.

The Fujifilm X100 series and X70 have leaf shutters.Ī leaf shutter is entirely different in build to a focal plane shutter, in that it’s a diaphragm that works much the same way as an aperture inside a lens.
