How to Clean Mirrorless Camera Sensor: A Quick Guide

 

Your mirrorless camera may have a variety of issues due to a dirty sensor. It can result in reduced image sharpness and potentially sensor failure in addition to lowering the quality of your images. In this post, we’ll provide you with a comprehensive how-to on cleaning a mirrorless camera sensor. We’ll address some frequently asked topics, offer practical advice, and demonstrate many techniques for correctly cleaning your sensor.

Maintaining the professional appearance of your images requires regular cleaning of your mirrorless camera’s sensor. It is inevitable that dust or debris will get inside any camera that has an exposed sensor. Some of my older photos have a lot of ugly sensor spot marks in the sky and other light regions.

Why is cleaning your camera sensor important?

Your camera’s sensor is its most crucial component. Maintaining your sensor is essential if you want to keep taking amazing pictures. Dust accumulation on your sensor can cause your photos to look patchy if you don’t clean it. If you change lenses frequently with a mirrorless camera, your sensor will become dirtier than it would be with a DSLR.

 

Considering that you won’t be changing lenses and subjecting your sensor to dust and debris, you may never need to clean your fixed-lens camera.

How Does Sensor Dust Appear, and What Is It?

Skin cells, lint, hair, and other microscopic particles are among the many diverse substances that make up sensor dust and can enter your camera. These particles can cause a variety of issues when they land on your sensor. 

First and foremost, they can result in “image contamination,” which lowers the quality of your photographs. At this point, the particles appear in your pictures as dark patches. In extreme circumstances, sensor failure may also result from sensor dust.

 

How can one determine whether they have sensor dust? Taking a picture of a blank white wall or piece of paper is the easiest approach to determine this.

How to Clean Mirrorless Camera Sensor: A Quick Guide

Step 1: Switch off the camera and take out the lens.

The lens can be removed by holding down the release button on the side of the camera body.  To release the lens, turn it counterclockwise while holding down this button.Once it’s loose, you may take it off the camera body. Keep a firm grip on both the lens and the camera body while doing this to prevent dropping either one.

Step 2: Take the Lens Out

You must take out the lens before you can begin cleaning your sensor. Usually, this is a rather easy procedure: simply unscrew the lens from the camera body. If you don’t know how to do this, see the manual that came with your camera.

Examine the sensor itself after removing the lens. As you can see, it has a very thin layer of dust on it. There is nothing to be concerned about because this is quite natural. The most crucial thing is to keep your sensor free of large particles of dirt or debris, as these could harm it.

Step 3: Sensor Cleaning

Now that you know how to reach the sensor and safely take out the lens, it’s time to start cleaning! A blower brush and a microfiber cloth are the most effective tools for cleaning a mirrorless camera sensor.

 

To begin, clear the sensor of any dust or dirt using the blower brush. To prevent unintentionally damaging the sensor, hold the blower brush at least six inches away from it.

 

NOTE: It’s time to begin cleaning with the microfiber cloth after you’ve cleared away all of the loose dust. To remove any remaining dirt or smudges, gently move the cloth back and forth across the sensor. To avoid damaging the sensor, always apply gentle pressure.

Cleaning tips for your mirrorless camera’s sensor

If you notice dust or other particles on your sensor, don’t panic! Your sensor can be kept clean and in good working order in a few easy steps. Here are some pointers and advice:

• Purchase a high-quality blower brush. This will assist in clearing your sensor’s surface of any loose particles.
• Only a clean sensor swab should be used to touch your sensor.
• Don’t use compressed air near your sensor or camera. In addition to harming your sensor, this may also harm other internal components of your camera.
• Keep your camera steady. The calibration may be affected if you have image stabilization.
• Avoid exposing your sensor for extended periods of time. You run the danger of getting more objects inside or on your camera sensor while you wait to clean it.
• Avoid splattering your sensor with water. This isn’t beneficial for anything and will harm your camera’s internal components.

Be careful to use a cleaning solution made especially for camera sensors if you must use one.  Using the incorrect kind of cleaning could harm your sensor. Be kind! Avoid using strong strokes to wipe the sensor’s surface; instead, use gentle ones. The fragile parts of your camera may sustain damage as a result.

You’ll need the following to clean your mirrorless camera sensor:

• A can of compressed air 
• A soft brush (like a paintbrush)
• Sensor swabs
• Cleaning solution

The sizes of the camera sensors match the diameters of the sensor swabs.

The size of the swab will increase with the size of the sensor. However, this does not exclude the use of a smaller swab on a bigger sensor. Actually, a lot of expert camera cleaning businesses advise utilizing a smaller swab for larger sensors. This is because a smaller swab will be less likely to leave smears or streaks on your sensor.

 

Naturally, you must exercise extra caution and ensure that you are not applying excessive pressure while using a smaller brush on a larger sensor. If you don’t, you could harm the sensitive sensor in your camera.

How to inspect your camera sensor for dust

Dust, grime, and other sporadic particles that adhere to the sensor in your DSLR or mirrorless camera are known as sensor spots. The good news is that mirrorless cameras’ sensors provide a live preview. The electronic viewfinder, or EVF, allows you to see what your camera is capable of. As a result, if you have any sensor spots, you also get a live glimpse of them.

 

When performing this preliminary check, make sure your aperture is high. The sensor spots are more noticeable as you reduce your aperture (for instance, from f/1.8 to f/22). It will be easier to identify the spots if you aim your camera at a bright light source and a constant hue. The texture of grass and stone walls will obscure any sensor spots when you’re staring at them.

 

The easiest way to check for dust or dirt on your sensor is to change the aperture to f/22 and take a photo of a white wall. You may zoom in on the image and pan around to see the exact amount of material on your sensor.

 

Using Lightroom to edit a photo is the second-simplest method. To identify all the flaws, you can change the exposure, tone curve, and contrast.

 

Even while you can perceive the flaws, they won’t always be completely apparent. You should make sure the image is as clean as possible before printing it!

 

How can I keep my camera’s sensor from developing sensor spots?

You can do the following to prevent sensor spots in the first place:

Make use of your camera’s anti-aliasing filter. This will reduce the likelihood of dust and other particles landing on your sensor.

 

Make sure the lens and body of your camera are clean. Dust and debris can easily land on your sensor if they are on your camera’s lens or body. Keeping both of them clean will also assist in keeping your sensor clean.

 

Change your lenses in a hygienic setting. There is a higher possibility that some dust or other particles will land on your sensor if you are changing lenses in an area that is crowded with them. Whenever possible, try to change lenses in a dust-free, hygienic setting.

 

Make use of a camera that has sensor cleaning built in. To help get rid of any dust or debris that might be on the sensor, some cameras incorporate a mechanism that vibrates the sensor. If this feature is available on your camera, use it frequently to help maintain the cleanliness of your sensor.

How to clean the sensor on your camera without using sensor swabs

It’s actually quite simple to clean your camera’s sensor without the need for sensor wipes. An oil-free cleaning cloth, a can of compressed air, and a little perseverance are required. Turn off your camera and take out the lens first. Next, find and activate the sensor cleaning menu in the menu system of your camera. This will allow you to reach the sensor by opening the shutter.

 

To prevent moisture from getting into the sensor, make sure you keep the can upright. After blowing away all of the dust on the surface, use your oil-free cleaning cloth to carefully wipe the sensor of any last bits of dust. Take care not to let your cloth come into contact with the sensor itself.

Advice on how to clean a camera sensor without a rocket blower or sensor swabs

To begin, remove the lens from your camera and take it out of its case.

You can use a blower brush to get rid of any obstinate dirt or debris that may be on the sensor.  After carefully inserting the brush inside the camera body, move it over the sensor’s surface.

 

You can use a cleaning solution made especially for camera sensors once you’ve cleared the sensor of all dirt and debris. 

After cleaning the sensor, put the camera back in its case and replace the lens.

Find where the dust is on the sensor

Determine the location of the dust on your sensor as a first step. You must take a photo of a white wall or piece of paper in order to accomplish this. 

After taking the photo, save it to your computer and enlarge it to 100%. Look for any dark areas or dots in the image; these are dust particles on your sensor.

Lowering the aperture may help make sensor dust spots less visible.

You can improve the depth of field by shooting at a lower aperture. Because they will be out of focus, any sensor dust spots will be harder to see in your pictures. Therefore, try shooting at a lower aperture and see if that helps if you are seeing sensor dust spots in your images.

 

Using the lens hood when shooting is another way to make sensor dust spots less noticeable.  The contrast of sensor dust spots in your images may be lessened by the lens hood, which partially filters light from entering the lens.

How to fix sensor dust spots using Adobe Lightroom

You probably don’t even need to physically clean your camera sensor to remove dust spots if you have Adobe Lightroom. Click on the “spot removal” tool (it resembles a circle with a dot in the center) in Lightroom’s develop module. Next, choose the “clone” option and just click on the dust spot-containing region of the image. Lightroom will automatically remove the dust spot by cloning over that region. It’s quite neat, isn’t it?

 

Naturally, this approach isn’t flawless and won’t be effective on every dust patch. However, before using more harsh steps like cleaning your camera sensor, it’s absolutely worth a try.

Attempting to clean your camera sensor as a last resort

It could be time to have your camera sensor cleaned by a professional after all previous attempts have failed. Given how costly and time-consuming it may be, this is typically a last resort attempt. However, if you have tried every other method, this might be the best approach to make sure your sensor is dust-free and clean.

 

You can look online for a professional camera sensor cleaning service or get referrals from your neighborhood camera shop. Once you’ve located a trustworthy service, they will usually clean your sensor securely and effectively using specialist equipment.
