How do i clean my 5d sensor

The mirror will lock up and the shutter will open. Clean the image sensor. Use a rubber blower to carefully blow away any dust, etc. Stop the cleaning. The camera will turn off, the shutter will close, and the mirror will go back down.

The camera will then be ready to shoot. During the sensor cleaning, never do any of the following that would turn off the power.

A few weeks ago I was on a mountain photo tour, and was constantly changing lenses in the windy and dusty alpine weather.

This is a photo taken to show you my sensor dust. All those black specks are fragments of airborne stuff that either gets sucked into your sensor when you use a zoom lens, or when you change your lens outdoors. The image above is the result. Check to make sure your sensor needs cleaning.

Do you see it? But if you see the dreaded black specs, read on. Many newer DSLRs have a special function for automatically cleaning the sensor. Look for it in the Tools menu on your camera. You may have to repeat this process several times. Sooner or later, even those photographers with auto-clean cameras will have to wash their sensors using this manual method, Step 2 below.

Sensor swabs are specially designed cleaning pads for camera sensors. If the power is cut off, the shutter will close and the shutter curtains and image sensor might get damaged. Clean the sensor with care. Use a plain blower without any brush attached. A brush can scratch the sensor. Do not insert the blower tip inside the camera beyond the lens mount. If the power is turned off, the shutter will close and the shutter curtains or reflex mirror might get damaged.

Never use canned air or gas to clean the sensor. The blowing force can damage the sensor or the spray gas can freeze on the sensor. If the battery level becomes low while you clean the sensor, the beeper will sound as a warning. Stop cleaning the sensor. If a smudge that cannot be removed with a blower remains, having the sensor cleaned by a Canon Service Center is recommended. Was this helpful?
