Why Do Mirrorless Cameras Have a Shutter?
Mirrorless cameras, unlike traditional digital SLRs (DSLRs), use an electronic viewfinder (EVF) instead of an optical viewfinder (OVF). This allows them to be smaller and lighter than DSLRs, while still offering many of the same features. One of the key differences between mirrorless cameras and DSLRs, however, is that mirrorless cameras have a shutter.
The shutter in a mirrorless camera is used to control the amount of light that enters the camera's sensor. When the shutter is open, light is allowed to reach the sensor, and the camera can take a picture. When the shutter is closed, light is blocked from reaching the sensor, and the camera cannot take a picture.
The shutter in a mirrorless camera is similar to the shutter in a DSLR. Both types of shutters are made up of two or more blades that move to open and close the shutter. However, there are some key differences between the two types of shutters.
The shutter in a DSLR is located in front of the camera's sensor. This means that the shutter must be moved out of the way before light can reach the sensor. This can cause a delay between the time that the photographer presses the shutter button and the time that the picture is taken.
The shutter in a mirrorless camera is located behind the camera's sensor. This means that the shutter does not need to be moved out of the way before light can reach the sensor. This results in a faster shutter speed, which can be beneficial for shooting fast-moving subjects.
Types of Shutters in Mirrorless Cameras
There are two main types of shutters in mirrorless cameras: mechanical shutters and electronic shutters.
- Mechanical shutters are similar to the shutters in DSLRs. They are made up of two or more blades that move to open and close the shutter. Mechanical shutters are very reliable and durable, but they can be noisy and can introduce vibration into the camera.
- Electronic shutters are not made of moving parts and are completely silent. They are also more durable than mechanical shutters and will not introduce vibration into the camera. However, electronic shutters can cause rolling shutter distortion, which can be a problem when shooting fast-moving subjects.
Advantages of Having a Shutter in a Mirrorless Camera
There are several advantages to having a shutter in a mirrorless camera.
- Faster shutter speeds: The shutter in a mirrorless camera is located behind the camera's sensor, which means that it does not need to be moved out of the way before light can reach the sensor. This results in a faster shutter speed, which can be beneficial for shooting fast-moving subjects.
- Reduced vibration: The shutter in a mirrorless camera is not directly connected to the camera's sensor, which means that it does not introduce vibration into the camera. This can be beneficial for shooting long exposures or when using a tripod.
- Silent operation: Electronic shutters are completely silent, which can be beneficial for shooting in situations where silence is required.
Disadvantages of Having a Shutter in a Mirrorless Camera
There are also some disadvantages to having a shutter in a mirrorless camera.
- Rolling shutter distortion: Electronic shutters can cause rolling shutter distortion, which can be a problem when shooting fast-moving subjects.
- Reduced battery life: Electronic shutters can use more power than mechanical shutters, which can reduce the battery life of the camera.
Do I Need a Mirrorless Camera with a Shutter?
Whether or not you need a mirrorless camera with a shutter depends on your individual needs. If you shoot fast-moving subjects or need to use a tripod, then you may want to consider a mirrorless camera with a mechanical shutter. If you are looking for a silent camera or want to conserve battery life, then you may want to consider a mirrorless camera with an electronic shutter.
Why Do Mirrorless Cameras Have a Mechanical Shutter?
Mirrorless cameras have a mechanical shutter because it provides several advantages over an electronic shutter.
- Faster shutter speeds: Mechanical shutters can achieve faster shutter speeds than electronic shutters, which is beneficial for shooting fast-moving subjects.
- Reduced rolling shutter distortion: Mechanical shutters do not suffer from rolling shutter distortion, which can be a problem when shooting fast-moving subjects.
- Increased durability: Mechanical shutters are more durable than electronic shutters and can withstand more wear and tear.
Why Do Mirrorless Cameras Have an Electronic Shutter?
Mirrorless cameras also have an electronic shutter because it provides several advantages over a mechanical shutter.
- Silent operation: Electronic shutters are completely silent, which can be beneficial for shooting in situations where silence is required.
- Reduced vibration: Electronic shutters do not introduce vibration into the camera, which can be beneficial for shooting long exposures or when using a tripod.
- Increased battery life: Electronic shutters use less power than mechanical shutters, which can extend the battery life of the camera.
