Recently whilst shooting and processing images I have noticed a number of dust spots on my images. Since i bought my Canon 5d second hand about a year ago now I thought it would be a good idea to clean the sensor becuase chances are the owner who had it before me probably hadn’t cleaned it.

I carried out a bit of research on the topic of cleaning the sensor and there were a lot of people out there that said basically don’t do it and send it off to Canon to be on the safe side. However there were also a large amount of photographers out there who had done it themselves. I decided to give it a go.

All you need to clean the sensor is sensor swabs and some optic cleaning fluid. These both can be found on Amazon (Sensor Swabs and Optic Cleaning Fluid).

Once you have these, carry out the following steps.

  1. Make sure that the battery is fully charged.
  2. Remove the lens.
  3. Turn on the camera.
  4. Press the menu button on the back and navigate to Sensor Cleaning.
  5. Select the OK option, this will expose the sensor.
  6. Get a sensor swab and put a couple of drops of cleaning fluid on it.
  7. Wipe the sensor one way, turn the swab over and wipe it back.
  8. Turn off the camera.
  9. Throw away the dirty sensor swab.

An there you have it, I was very impressed how quick and how painless this was to carry out, rather than having to post it Canon, having to wait and probably having to pay a hell of a lot more money!
