Dust in Retractable Lens - PowerShot G7 X Mark III

[smoore1271]

Hi everyone,

I have a PowerShot G7 X Mark III and there is dust in the retractable lens, possibly on the back of the glass. It looks like there is a flat rate of $380 to send this into Canon to get fixed, but I am not sure if they can even fix it? I have not been able to get an answer from Canon on if this is possible.

Wondering if anyone else has had this issue and if they have fixed it? I have seen videos on drilling a small hole through the lens barrel but is definitely not ideal.

Thanks!!

Welcome to the forum.

How severe is the problem? It is not uncommon to have dust in a lens, particularly lens that change size when zooming. As the lens extends and retracts it "breathes" and air is brought in. Air that contains dust to a greater or lesser dgeree, depending on the environment.

Is it affecting your image quality?

Even if a somehow drilled a hole in the barrel and removed the dust (a very bad idea IMHO) it will return as you use the camera.

Hi!

It is affecting image quality. Multiple black spots in photos, large and small and worse in bright light. If I sent it in I am not sure if it is even fixable since it is a retractable lens?

Thanks,

If it is visible, then it is probably dust on the image sensor, which does not mean there isn't any dust inside of the lens ass'y.
