Mirrorless cameras have revolutionized the world of photography with their compact size, lightweight design, and advanced features. However, one key component that sets them apart from traditional DSLR cameras is the absence of a mirror mechanism. So, why do mirrorless cameras still have a mechanical shutter?
Even though mirrorless cameras do not have a mirror to flip up and down like DSLRs, they still require a mechanical shutter to control the exposure of light onto the camera sensor. The mechanical shutter in a mirrorless camera serves the same purpose as in a DSLR – it opens to allow light to enter the sensor for a specific duration, capturing the image, and then closes to end the exposure.
Why Mirrorless Cameras Use Mechanical Shutter
Mirrorless cameras use mechanical shutters for several reasons:
- Control Over Exposure: Mechanical shutters provide precise control over the exposure time, allowing photographers to capture images with specific shutter speeds.
- Reduced Rolling Shutter Effect: Mechanical shutters help reduce the rolling shutter effect, which can distort fast-moving subjects in electronic shutter systems.
- Physical Barrier: Mechanical shutters act as a physical barrier between the sensor and light, preventing overexposure and ensuring accurate image capture.
- Longevity: Mechanical shutters have a longer lifespan compared to electronic shutters, offering durability and reliability for long-term use.
Overall, the use of mechanical shutters in mirrorless cameras enhances image quality, control, and reliability in various shooting conditions.
Role of Mechanical Shutter
One of the key reasons why mirrorless cameras have a mechanical shutter is to control the exposure time of the sensor. The mechanical shutter physically opens and closes to let light in for a specific duration, allowing the sensor to capture the image. This mechanism ensures precise timing and control over the exposure, resulting in accurate and consistent image quality.
Benefits of Mechanical Shutter:
- Precise control over exposure time
- Ability to capture fast-moving subjects with minimal motion blur
- Enhanced image quality and sharpness
Advantages of Mechanical Shutter
Although mirrorless cameras typically rely on electronic shutters, there are some advantages to having a mechanical shutter:
1. Durability
Mechanical shutters are known for their durability and longevity. They can withstand a high number of actuations without experiencing significant wear and tear, making them a reliable choice for professional photographers who shoot frequently.
2. Mechanical Feel
Some photographers prefer the tactile feedback and mechanical feel of a traditional shutter mechanism. The physical sensation of pressing the shutter button and hearing the click can provide a sense of connection with the camera and the act of taking a photograph.

Impact on Image Quality
Having a mechanical shutter in a mirrorless camera can significantly impact image quality in a positive way. The mechanical shutter helps to control the exposure time and ensures that the image sensor is exposed to light for the correct amount of time, resulting in sharper and more accurate images. Additionally, the mechanical shutter can reduce the chances of image distortion and rolling shutter effect, which can occur in electronic shutters.
By using a mechanical shutter, photographers can achieve better control over motion blur and capture fast-moving subjects with more precision. The mechanical shutter also contributes to better dynamic range and improved color accuracy, making it an essential component for capturing high-quality images with mirrorless cameras.
Comparison with Electronic Shutter
While mirrorless cameras often come equipped with a mechanical shutter, they also have the option of using an electronic shutter. The choice between the two depends on the specific needs of the photographer.
Mechanical Shutter: A mechanical shutter consists of physical curtains that open and close to control the exposure time. This type of shutter is known for its reliability and ability to capture fast-moving subjects with minimal distortion.
Electronic Shutter: An electronic shutter, on the other hand, uses electronic sensors to capture the image without the need for physical moving parts. It offers silent operation and can achieve extremely fast shutter speeds, making it ideal for capturing action shots without any noise.
Ultimately, the decision to use a mechanical or electronic shutter depends on factors such as desired image quality, shooting conditions, and personal preference. Both options have their own advantages and drawbacks, so it’s important for photographers to experiment and determine which shutter type best suits their needs.
