I have a cannon powershot sx100is 10X optical zoom. Maybe two,three years,
don't remember,(age does that to a person) If I take a picture with light backround
there is always a small dull spot in the same section of the picture some might not notice it, but I do. The more zoom I go, the more it goes to the edge, and then out of the picture. I cannot see the spot when looking at the screen on the camera. I have taken quite a few sunset/sunrise pics. Someone told me the spot could be a (burn in) on the optics from the sun. Is this possible?? If it is, I guess we should say beware of (sun) pictures. Thanks in advance for your help
If the spot is moving, it sounds more like something on the lens, either inside or outside.
DSLR cameras (due to changing lenses) will sometimes develop a spot when the sensor gets dirty, but that is always in the same location.
I have never heard anything regarding "burn", but who knows
Right there with Kevin. But, you dont have a DSLR in this case, as it is a Powershot. Most cameras nowadays are "disposable",. The sensors can just die., and it isn't worth replacing them. Happened to me on one of THE most important "take a picture days" in my life, after 3 loya years with a Powershot, which is likely why I still rave my film cameras, which are up to 30 years old, and still work great.
But, at least in my case, if a sensor is bad, nothing worked, and everything was a blur of color.
Could be mold on th lens(?) If that is the case, chuck it, and move on!
My Canon Powershot A480 developed the same 'spot' issue 2 months after I bought it. A quick call to Canon and they will fix or replace the sensor at no cost to me (shipping from me is my $$$ but that is minor).
As a temporary fix I noticed that if I lowered the exposure against light backgrounds I can decrease or eliminate the spot. Since most of my pics have that area full of color or totaly dark, it's not a huge issue for me. I will take advantage of the warranty and have them fix it soon.
The only way it could be on the sensor if it "moves" with the level of zoom, is if zooming causes a smaller portion of the sensor to be used... which doesn't sound right to me. You could do a test: shoot one shot fully zoomed in, one zoomed out, and if they're the same pixel width and height then it's not the sensor. So it sounds like something in the lens mechanism itself, although how sunlight is meant to burn glass I don't know; maybe it's a bit of dust that crept in there? Might want to pop along to a local independent specialist and see if they'll take a look at it, they might be able to tell what's causing it from the characteristics of the spot on the images.

Hope that Helps.
