Do Mirrorless Cameras Have a Shutter

Mirrorless cameras have gained significant popularity in recent years due to their compact size, versatility, and excellent image quality. As photographers explore this technology, a common question that arises is whether mirrorless cameras have a shutter. In this article, we will delve into the functioning of mirrorless cameras and shed light on the presence or absence of a shutter mechanism. So, let’s uncover the truth and dispel any confusion surrounding this topic.

Understanding Mirrorless Cameras

Before we dive into the specifics, let’s briefly understand what mirrorless cameras are and how they differ from traditional DSLRs. A mirrorless camera, as the name suggests, lacks the internal mirror found in DSLR cameras. This absence of a mirror allows for a more compact and lightweight camera body, making mirrorless cameras an attractive option for photographers seeking portability without compromising on image quality.

Do Mirrorless Cameras Have a Shutter?

To answer the burning question, yes, mirrorless cameras do have a shutter mechanism. However, it’s important to note that the shutter mechanism in mirrorless cameras functions differently than in DSLRs. In a DSLR, the mirror reflects the image from the lens into an optical viewfinder, and when the shutter button is pressed, the mirror flips up, exposing the camera’s sensor to capture the image.

In contrast, mirrorless cameras utilize an electronic viewfinder or the rear LCD screen to display the image directly from the camera’s sensor. The absence of a mirror means that the light is continuously hitting the sensor, which allows for a real-time preview of the image. When the shutter button is pressed, the electronic shutter in a mirrorless camera controls the duration of exposure by electronically opening and closing the sensor.

How Does the Electronic Shutter Work?

The electronic shutter in mirrorless cameras operates by turning the camera’s sensor on and off rapidly to control the exposure. When the electronic shutter is activated, the sensor collects light information for the designated exposure duration. Unlike a mechanical shutter, there are no moving parts involved in an electronic shutter, resulting in silent operation and minimizing the risk of camera shake caused by the shutter movement.

Advantages of an Electronic Shutter in Mirrorless Cameras

The inclusion of an electronic shutter in mirrorless cameras offers several advantages for photographers:

  1. Silent Operation: Since there are no physical moving parts, mirrorless cameras with an electronic shutter operate silently, making them ideal for situations where minimal noise is desired, such as weddings, wildlife photography, or street photography.
  2. Increased Shutter Speed: Electronic shutters in mirrorless cameras can achieve incredibly high shutter speeds, allowing photographers to freeze fast-moving subjects with precision and clarity. This can be especially beneficial in sports and action photography.
  3. No Shutter Wear: With no mechanical components, the electronic shutter doesn’t suffer from wear and tear like traditional shutters in DSLRs. This translates to a longer lifespan for the camera and reduces the need for costly shutter replacements.
  4. Anti-Distortion Capabilities: Electronic shutters minimize the occurrence of rolling shutter distortion, which can be a common issue in some fast-paced shooting scenarios. This distortion can cause subjects to appear skewed or distorted, but with an electronic shutter, this problem is significantly reduced.

Choosing the Right Camera for Your Needs

When selecting a camera, it’s important to consider your specific requirements, including the presence or absence of a mechanical shutter. Evaluate your shooting style, preferences, and the type of photography you intend to pursue. Both mirrorless cameras with and without mechanical shutter have their unique advantages and limitations. Make an informed decision based on your needs and the features that align with your creative vision.

In conclusion, mirrorless cameras do have a shutter mechanism, albeit in a different form than traditional DSLRs. The electronic shutter in mirrorless cameras offers numerous advantages such as silent operation, increased shutter speed capabilities, and longer lifespan due to the absence of mechanical parts. While there may be some limitations, advancements in technology are continuously improving electronic shutters, making them a viable and attractive option for photographers across various genres. So, embrace the versatility and innovation of mirrorless cameras and let your creativity soar!


Can mirrorless cameras capture fast-moving subjects without a shutter?

Yes, mirrorless cameras with electronic shutters can capture fast-moving subjects with precision and high burst rates.

Do mirrorless cameras produce any sound while taking photos?

Mirrorless cameras without a mechanical shutter operate silently, producing no sound during image capture.

Are mirrorless cameras more prone to shutter failure?

Mirrorless cameras without a mechanical shutter experience fewer mechanical failures since they lack moving parts, making them more durable.

Can mirrorless cameras achieve long exposure shots without a mechanical shutter?

Mirrorless cameras can achieve long exposure shots using the electronic shutter option, which electronically controls the light exposure duration.

Do mirrorless cameras have any advantages over traditional cameras with a shutter?

Yes, mirrorless cameras offer advantages such as compactness, silent operation, and increased durability compared to traditional cameras with mechanical shutter.

Do mirrorless cameras have a mechanical shutter?

Yes, mirrorless cameras do have a mechanical shutter in addition to the electronic shutter. The mechanical shutter is typically used in scenarios where the electronic shutter may not be suitable, such as when shooting with external flashes or in extremely bright lighting conditions.

Can I switch between the electronic shutter and mechanical shutter?

Most mirrorless cameras allow you to switch between the electronic shutter and mechanical shutter based on your shooting requirements. This flexibility ensures that you can adapt to different situations and achieve optimal results.

Are there any downsides to using the electronic shutter?

While the electronic shutter offers numerous advantages, it may have limitations when it comes to capturing fast-moving subjects. Due to the way electronic shutters read the image sensor, rolling shutter effects can occur, causing distortion in the image. However, modern mirrorless cameras are continuously improving in this aspect, and the issue is becoming less prevalent.

Can the electronic shutter produce motion blur in certain situations?

In situations where there is excessive movement or very fast motion, the electronic shutter may introduce motion blur due to the way it scans the image sensor. To mitigate this, it is recommended to use the mechanical shutter or select a suitable shutter speed when shooting such subjects.

Are there any differences in the electronic shutter performance across different mirrorless camera brands?

Yes, there can be variations in electronic shutter performance between different mirrorless camera models and brands. It is advisable to consult the camera’s specifications or try out the camera in person to determine the suitability for your specific needs.

Can I use the electronic shutter for long exposures?

Electronic shutters can indeed be used for long exposures, allowing photographers to capture stunning images of starry nights, light trails, or other low-light scenarios. However, it is important to be aware of the potential for sensor overheating, which can introduce noise or other artifacts into the image. Some cameras may also have a maximum exposure time limitation when using the electronic shutter.
