How to Research a Digital Camera's Anti-Dust System

Digital cameras utilize an imaging sensor needs cleaning from time to time. Small, almost imperceptible particles adhere to the imaging sensor, causing damage or light diffraction. Once on the imaging sensor, the dust appears as small undesirable dark areas on the finished image. Many digital cameras offer an anti-dust system built into the camera body.

Instructions

Difficulty: Moderately Easy

1. Look through the camera's on-board menu system for details on the method used to remove dust and debris. There are commonly information screens associated with each function.
2. Determine whether the user needs an in-camera dust removal system or an in-lens dust removal system. In-camera systems offer the added feature of working with every lens put on the camera, whereas the lens only system requires the lens provide the feature.
3. Review digital camera forums online for a first hand experience with particular anti-dust removal systems. People that own the camera have an unbiased opinion of the feature and are more apt to provide an honest review.
4. Use the feature on the camera. Try it out at the camera store when considering the purchase. Ask a staff member to allow a test drive of the device.
5. Ask the camera sales staff at any local camera store about the anti-dust system for that particular camera. This is a common feature that most staff members know quite a bit about.
6. Read over the digital SLR camera's owner's manual for information on that particular camera's anti-dust removal system. Every camera model is different, and there's a section in the manual that covers the entire dust removal process.

Tips & Warnings

• Digital SLR cameras are an expensive investment. Hold, shoot and inspect closely before purchasing.
• See if the camera has a self-cleaning mechanism built into the system. Some cameras shake the dust off the low-pass filter in front of the imaging sensor. Others require the user to swab away the particles while the mirror is in the up position.
• Never clean the imaging sensor without first reading the camera manual. This piece of the camera is easily damaged.
