Instead, they capture light from the lens straight to the sensor. Compact Cameras and SmartphonesĮver wonder where the clicking from your compact camera or smartphone comes from? The truth is that sound is produced electronically.Ĭompact cameras and smartphones don’t have shutter curtains that go up and down at all. You can use it for high sync flash that can be 1/1000th of a second or more, as compared to 1/200 or 250th of second for mirrorless and DLSRs. The advantage of a leaf shutter is that it’s faster than any other mechanism that employs a shutter curtain. It also looks and works like an aperture, moving inwards or outwards instead of up and down. Unlike other shutter mechanisms, a leaf shutter is inside the lens and not the camera body. But the high-end medium-format options often feature a special shutter called a leaf shutter. That means that their shutter mechanisms also vary. Just like full-frame cameras, medium-format cameras also have DSLR and mirrorless versions.

Only a small percentage of professional photographers get to use them on a daily basis. Since medium-format cameras have a bigger sensor and resolution, they’re very expensive. Full-frame sensors are the ones that most professional photographers use.īut what about medium-format cameras? Medium-format got its name from 120mm format cameras during the film days. Crop-sensors are typically found in cheaper consumer cameras. We’ve all heard of crop-sensor and full-frame cameras. Once the exposure is done, another door goes down from the top of the frame. But when you press the shutter button, a shutter door goes up to block the sensor, and then goes down to make the exposure. Since a mirrorless camera doesn’t have a mirror, the sensor is fully exposed behind the lens. But the difference this time is the way it moves and captures the image as you press the shutter button. It also has a shutter curtain that goes up and down as you take a picture. In many ways, the shutter mechanism of a mirrorless camera works similarly to DSLRs. Mirrorless cameras transmit image data from the sensor to a small electronic screen in the viewfinder to let you see what you’re shooting. Mirrorless cameras are called such because they don’t have the mirror that DSLRs have. The slower the shutter speed, the longer the shutter is open. The amount of time the first curtain goes down and the second curtain goes down depends on the shutter speed. Once the exposure is finished, a second curtain goes down and covers the sensor. While the mirror is up, a shutter curtain goes down and exposes the sensor behind it. Since it’s not reflecting any light behind the lens and directing it to your viewfinder anymore, you get a black screen. When you press the shutter button, you’ll hear the mirror make a slapping sound when it goes up. But the DSLR is designed in such a way that when you press the shutter button, the mirror goes up so the shutter can open and make an exposure. Now, what does the mirror have to do anything with the shutter? Well, since the mirror is directly behind the lens, it prevents the light from hitting the shutter. You can think of it as a tiny periscope that bounces light around to reach your eye. The optics of the DSLR works by placing a mirror behind the lens, which goes to a prism inside your viewfinder. This lets you see exactly what goes through the lens. That means that your camera has an optical device composed of a mirror and a prism. The acronym stands for Digital Single Lens Reflex.

How Does a Camera Shutter Work? DSLR Shutterīefore we start, let’s define DSLR to understand how its shutter works. Let’s have a look at the shutters you’ll find in DSLRs, mirrorless, video, and motion picture cameras. There are various types of shutters that work differently depending on the camera. It’s not just a simple gate that opens and closes. In reality, a shutter is a complicated mechanical contraption. You can think of it as a gate that opens to let the light into the sensor or film and closes to stop the exposure.
