What is sensor dust? It is dust that settles on your camera’s sensor. Your sensor can get dust on it when you’re changing lenses or anytime your camera’s insides are exposed to air. Sometimes even new cameras have sensor dust!
If you’ve ever seen those tiny spots in your pictures, usually noticeable on blue sky, you’ve seen sensor dust. You know it can be quite annoying and distracting and can ruin good pictures.
I have personally used the “Altura Photo Professional Full Frame Sensor Cleaning Kit – Camera Cleaning Kit for FF DSLR & Mirrorless Cameras – w/Sensor Cleaning Swabs & Case, Works as Camera Lens Cleaning Kit, Sensor Cleaner ” and have obtained excellent results (Product link by Amazon.com). It comes with all the sensor swabs etc. you need. Just make sure you order the kit that fits your DSLR Sensor size!
Why is sensor dust bad?
Sensor dust is not something you want in your camera. Like I mentioned above, it can ruin your images. You can Photoshop it out, but this is incredibly monotonous and time-consuming.
If dust stays on your sensor, it can become thicker, more noticeable, and harder to remove. If you notice sensor dust in your camera you should get rid of it as soon as possible.
