    Its at the bottom right corner. When I look through the view finder I can see it there and a few other specs. I tried cleaning the lense but it still shows up. Is it on the sensor? I was hiking and all the sudden I saw it on there so it got dirt or sand in there some how. I didnt take the lense off so im not sure how it could have gotten in there. I took the lense off when I got home and I couldnt see anything in there really. Any clue whats up? Should I take it to a shop to have looked at or try to clean it myself somehow?

    its on or very close to the sensor. You notice dust more when you use a small aperture, take a photo of say a white wall @ F/22, moving the camera as you do it. This will show you all the dust on your sensor and you'll be supprrised how dirty it is! You have to look behind the shutter to see it (although its probably about 1mm in size), and will be on the opposite side.

    You need to use mirror lockup to clean it. You could try a blower, they're easy to use but imo they often put more dust on then they take off.

    This is what I use:

    But its a bit overkill for that small amount of dust. Try the blower or take it to a camera store, they can often use compressed air on it.

    How do you use the mirror lock up function to clean it?

    this maybe more than one problem. if you can see it in the viewfinder, then its on the lens or mirror. If its on the mirror only, then it won't show in the pic. If it shows in the pic, then its on the lens (check both sides)


    dust gets everywhere. cleaning the sensor is something to reseach very carefully, and find a solution to the problem that works for you, as you will keep having to do it the more you shoot.

    ah I didnt notice that you can see it through the viewfinder. It may be on back of the lens?

    Be careful you dont add more dust doing this, as viper said do some reading on the best processes to keep dust out & how to clean.

    Canon: switch to manual mode, use the sensor clean option in the menu with no lens attached. Turn off when done.
    Nikon: :greddy:

    Im looking at the back of the lense and I think it might be Inside the lense. Looks like a really really tiny strand/fiber, but its inside. how could it get in there?

    also had some dust inside on the sensor ( i think thats what im thinking of, but the angled thing right when u look in)
     
  9. Yea I have a hair from japan on my mirror. I can see it in the viewfinder but it doesn't show in the pics. It really doesn't bother me so I havn't done anything about it :hs: Plus I don't know what to do to fix it. Derrict? :x: :hs:

    I read that Scotch magic tape or Post It book marker (ones in little plastic container) works well from dpreview forums. There are few people who tried it, and they seem to be happy w/ the result. Rationale behind it; lifting dust particles off is safer than rubbing dust particles across the low pass filter.
     
  11. Good luck with that, try it and tell us how much glue/residue you leave on your mirror :hsugh:

    That was most people's reaction. I tried it on my filter it left no residue. When I do clean my CCD this way I'll let you know.

    I could see a black speck through my viewfinder the other day and it wasn't on the lens or mirror. It was on the part of the viewfinder that has the focus sensors on it. I just took a lens cloth and wiped it down, but don't know how it got there.

    So if dust is showing up in the viewfinder and on my pictures, does that mean its not on the mirror, but instead the lense?

    I tried cleanign the lense but its till coming up.

    I looked inside the back of the lense and it looks like there is some dust INSIDE it. can that be fixed? how did it get in there?

    For that I'd use the rocket. Dust can creep in even while you have your lens on your body, between the seam. Unless, your lens has rubber gasket seal.

    Marks like that can be crap on the front element of the lens too. With higher apertures I was getting a clear outline of a hair that had stuck on the front of my lens.

    Always make sure your lens is clean before suspecting the sensor.
