Dusty Sensor, A Common Issue in Digital Cameras

Regardless of how careful you take care of your digital camera, at one point, you look at your photos, and you will notice few dark spots on the image (especially on the sky or plain area of the photo). Don’t get so excited that you have captured UFOs pictures! No, you haven’t! In fact, those dark spots mean Dusty Sensor


It sounds terrifying having Dust on a digital camera sensor, but it is a common issue in almost all digital cameras. In a series of articles, I will discuss how to reduce the chance of getting Dust on the Sensor, clean the Sensor, and use Lightroom or Photoshop to remove the Dust from photos.

How Dust Gets on the Sensor

These dust particles are very tiny, and they are floating around us all the time. Changing a lens, or zooming in and out, causes Dust to enter the camera and sits on the Sensor. 

The digital camera sensor has a strong static charge, and this static charge works like a magnetic field that attracts dust particles. When the dust particles sit on the Sensor, they get stuck there till you do something to get rid of them.

Which Cameras are More Prone to Get Dusty Sensor

Generally speaking, all digital cameras, but DSLR and Mirrorless cameras are more prone to Dust. Changing a lens or zooming with the zoom lenses, the air gets sucked into your camera and brings dust particles along with it!

There are many simple steps that you can take to avoid getting Dust on the Sensor. Stay tuned for upcoming articles as I will discuss how to reduce the chance of getting Dust on the Sensor, clean the Sensor, and use Lightroom or Photoshop to remove the Dust from photos.



1- Turn off the camera while changing the lens.

2- Use a blower or a brush to remove Dust particles from around the lens mount in a Dusty environment.

3- Change the lens while holding the camera in the correct position. 

Changing Lens Correctly to Avoid Dusty Sensor

Another risk factor of getting dust on the sensor is changing the lens. When you change the lens, you expose the camera’s internals to the outside elements such as dust particles and pollen (pollens are especially very sticky). Here is another easy step for you to prevent getting dust on the sensor. I have seen many people change the lens while laying their cameras on a surface face up!

Wrong Way of Changing Lens

This is a wrong way of changing the lens. The gravity helps the dust getting inside your camera.

By changing the lens in this way, gravity helps the dust particles fall inside the camera!

In the picture below, I showed a correct way to change the lens and reduce getting dust inside the camera. Please practice this step a couple of times on top of a soft area to master it. You don’t want to drop your precious lens on the hard floor!
