As a photographer, you may have noticed that your mirrorless camera sometimes produces sounds similar to those of a DSLR. This can be quite puzzling, especially if you switched to a mirrorless camera to avoid the noise associated with traditional DSLRs. So, why does this happen?
The main reason for the noise in mirrorless cameras is the autofocus system. Unlike DSLRs, which use a mirror mechanism for autofocus, mirrorless cameras rely on contrast detection or phase detection autofocus systems that can produce some noise during operation.
This noise is typically more noticeable in quiet environments or when shooting video, but it’s a normal part of the camera’s operation. Understanding why your mirrorless camera sounds like a DSLR can help you better appreciate the technology behind these compact and versatile cameras.
Common reasons for mirrorless camera sounding like a DSLR
When your mirrorless camera starts sounding like a DSLR, it can be concerning. Here are some common reasons for this unexpected noise:
1. Autofocus Mechanism
One of the main reasons for the sound could be the autofocus mechanism in your mirrorless camera. Some mirrorless cameras use contrast detection autofocus, which can be slower and noisier compared to phase detection autofocus found in DSLRs.
2. Image Stabilization System
Another reason for the noise could be the image stabilization system in the camera. The movement of the stabilization components can sometimes produce audible sounds, especially in certain shooting conditions.
Mirrorless Camera Design and Mechanics
Unlike traditional DSLR cameras, mirrorless cameras do not have a mirror mechanism. This design choice contributes to their compact size and lower weight.
Instead of the mirror that directs light to the optical viewfinder in a DSLR, mirrorless cameras use an electronic viewfinder or LCD screen to display the image in real-time. This electronic viewfinder is powered by the camera’s sensor, providing a digital preview of the scene.
The absence of the mirror mechanism in mirrorless cameras also means they operate quietly compared to DSLRs. The lack of moving parts reduces the noise produced during operation, resulting in a quieter shooting experience.
Additionally, the mirrorless design allows for faster autofocus performance since the camera can continuously focus without the need to lift and drop a mirror. This contributes to the overall efficiency and speed of mirrorless cameras in capturing fast-moving subjects.

Autofocus system differences
One reason why your mirrorless camera may sound like a DSLR is due to the autofocus system. Mirrorless cameras use contrast-detection autofocus, which involves the camera constantly adjusting the focus until it detects the highest contrast in the scene. This can result in the camera making small adjustments to the focus, which may produce a sound similar to a DSLR’s autofocus mechanism.
On the other hand, DSLRs typically use phase-detection autofocus, which is generally faster and more precise than contrast-detection autofocus. This difference in autofocus technology can contribute to the sound differences between mirrorless and DSLR cameras.
Shutter sound variations
One of the noticeable differences between mirrorless cameras and DSLRs is the sound they produce when taking a photo. The shutter sound of a camera can vary depending on the model and brand.
DSLR cameras typically have a louder and more pronounced shutter sound due to the mirror mechanism inside the camera that flips up and down to allow light to reach the sensor. This mechanical movement creates a distinct noise that is often associated with traditional photography.
On the other hand, mirrorless cameras use an electronic shutter or a quieter mechanical shutter mechanism that results in a softer and less audible sound when capturing an image. The lack of a mirror flipping up and down contributes to the reduced noise level, making mirrorless cameras a popular choice for photographers who prefer a quieter shooting experience.
While some photographers enjoy the reassuring click of a DSLR shutter, others appreciate the discreet and unobtrusive shutter sound of a mirrorless camera. Ultimately, the choice between the two comes down to personal preference and shooting style.
| DSLR Camera | Mirrorless Camera |
|---|---|
| Louder and more pronounced shutter sound | Softer and less audible shutter sound |
| Mechanical movement of mirror creates noise | Electronic or quieter mechanical shutter mechanism |
| Traditional click sound | Discreet and unobtrusive sound |
Lens compatibility and noise
One possible reason why your mirrorless camera sounds like a DSLR is due to the compatibility of the lenses you are using. Some lenses, especially older or third-party ones, may not be fully compatible with mirrorless cameras, causing them to produce more noise during focusing or operation.
When a lens is not fully optimized for a mirrorless camera, it may struggle to communicate effectively with the camera body, leading to increased noise levels. This can be particularly noticeable when the autofocus system is engaged or when the lens is adjusting its aperture.
Sensor size impact on camera noise
One of the key factors that can influence the sound of a mirrorless camera is the sensor size. In general, larger sensors have larger pixels, which can capture more light and produce less noise. This means that cameras with larger sensors, such as full-frame mirrorless cameras, tend to have better low-light performance and produce less noise compared to cameras with smaller sensors, like APS-C or micro four-thirds.
When a camera is operating in low-light conditions or using higher ISO settings, the sensor needs to amplify the signal to produce a usable image. In cameras with smaller sensors, this amplification process can introduce more noise into the image, resulting in a grainy or noisy appearance. On the other hand, cameras with larger sensors require less amplification, leading to cleaner images with less noise.
Firmware updates and noise reduction techniques
One of the reasons why your mirrorless camera may sound like a DSLR is the noise generated by the camera’s internal mechanisms. However, firmware updates can often address this issue by optimizing the camera’s operation to reduce unnecessary noise.
Firmware Updates:
- Check for firmware updates on the camera manufacturer’s website regularly to ensure you have the latest version installed.
- Firmware updates may include improvements in noise reduction algorithms or adjustments to the camera’s settings to minimize noise during operation.
Noise Reduction Techniques:
- Adjust the camera settings to use lower ISO settings, as higher ISO levels can often lead to increased noise in the images.
- Use noise reduction software or tools during post-processing to reduce noise in images captured with your mirrorless camera.
FAQ
Why does my mirrorless camera produce a sound similar to a DSLR?
Some mirrorless cameras use a technology called an electronic first curtain shutter, which can produce a sound similar to a DSLR’s mechanical shutter. This is because the electronic first curtain shutter combines an electronic shutter with a physical shutter, creating a sound that may resemble a traditional DSLR’s shutter noise.
Is it normal for mirrorless cameras to make noise like a DSLR?
Yes, it can be normal for some mirrorless cameras to produce a sound similar to a DSLR. This is often due to the type of shutter mechanism used in the camera, such as an electronic first curtain shutter. While mirrorless cameras are generally quieter than DSLRs, some models may still have a noticeable sound when taking a picture.
Can I reduce the sound of my mirrorless camera that resembles a DSLR?
You may be able to reduce the sound of your mirrorless camera by adjusting the settings to use an electronic shutter or silent shooting mode, if available. These modes can help minimize the noise produced when taking a photo. Additionally, using a lens with a quieter autofocus motor may also help reduce any operational sounds of the camera.
Does the sound of a mirrorless camera affect its performance?
The sound of a mirrorless camera, whether it resembles a DSLR or not, typically does not affect its performance. The noise produced is usually a result of the shutter mechanism and does not impact the camera’s ability to capture images or video. However, if the sound is significantly loud or bothersome, you may want to consider adjusting the camera settings to reduce it.
Are there any advantages to a mirrorless camera sounding like a DSLR?
While the sound of a mirrorless camera resembling a DSLR may not necessarily provide any advantages in terms of performance, some photographers prefer a camera that gives audible feedback when taking a picture. The sound can create a sense of familiarity for those transitioning from a DSLR to a mirrorless camera, helping them feel more connected to the shooting process.
