Weird black/grey dot on my photos?

Thank you!

That looks like a "dust bunny" to me.  I've had three Canon Rebels for over 4 years and only once did I find something like that.  It was on one side, so it wasn't critical that I remove it right away.  I was beginning to read about it, to find out if I could clean the sensor myself or have it done by a professional.  What I remember reading is to be careful to do it right, otherwise further problems could develop.  Fortunately over a period of weeks, the dust bunny got smaller and smaller and eventually went away.  That's one reason I feel the in-camera dust sensor protection is necessary.  I don't normally change lenses so that may also contribute to the fact that this rarely is a problem for me (I have multiple cameras with attached lenses).  But I read anyone can potentially get these dust particles (depending on their gear).  Once I had a dust bunny on my Kodak P&S camera.  But that went away on its own and then I stopped using the camera, because later new improved technology led me to other cameras.  That ended any future problems with dust with that.  My Olympus DSLR cameras had great internal dust sensor protection, so that wasn't a problem at any time.  I'm glad that my Canon DSLR cameras appear to be performing well that way also with this in-camera dust protection.

You could have the camera clean the sensor itself over & over and see if it goes away on its own.  Hopefully, you'll see it getting smaller and smaller and then soon it will be gone.  If that doesn't work, then cleaning the sensor yourself seems easy enough, but again it's important that you do it correctly.  There's enough information about this on the internet that should help you in that regard.  If you feel that you are not good at this type of thing, you might find a camera shop to do this for you professionally.  Check them out to see what price they would charge.  I think they would charge about one hour of labor or so.  It shouldn't be a lot of money, but I wanted to learn how to do it myself, because who knows how many more times it may happen.  I'm so busy, that I still have never done my own sensor cleaning.  Thank goodness for Canon's technology to reduce this occurrence.

I have had 3 Powershots, the latest is the 120. They have ALL developed this after a couple of years. Since it's not possible to clean the sensor like with a SLR, I'm forced to just live with it, spend big bucks and wait for a repair, or buy a new camera. I hate to continue this cycle, but I love the teensy size and light weight of these cameras, and of course, the RAW ability. Here's a recent illustration showing how bad it's getting. You can see the two big gray squiggles in the sky and at least two more on the earth. It's funny that Canon doesn't even mention this problem in their support area, at least that I can find. When I called about it two cameras ago, they said mail the camera in and they'd replace the sensor, and it would be weeks and cost big bucks.

What gets me is that it's clearly a sensor flaw and not dust. If it were dust it wouldn't look like this, I don't think. I don't shoot in bad environments much at all.

So I am thinking of getting a Canon G9x Mark II since this clearly needs replacement. Anybody have one and have feedback? Thanks!

You might want to ask that question on the Canon PowerShot forum.  If you would like a Canon DSLR that is relatively lightweight and inexpensive and has dust sensor protection, consider the Canon SL2 (200D) camera.

No it's sensor dust. Greatly helps to not put cameras in clothing po keys that can have lint to easily get in the camera. Use a camera bag instead and keep it in a drawer, cupboard,  etc

Yes it would that's a string like of something

Storage is the issue

Use a camera bag

I own a Canon G9x Mark II. I used it a lot, loved the camera until the 6th month. Then I had a black spot on all of my photos. I cleaned the lens but there is no way I can find to clean the sensor. I think this happens to all camera but is a really problem when they are point and shoot camera.
