    Default Sensor scratch

    Has anyone had to get their sensor replaced or fixed? Just wondering what that entails. Noticed marks on my photos today and boom, there is a scratch on the sensor. I'm no fixer... x

    Don't want to overlook the obvious. Have you tried changing lenses? Also, it may only be dust on the sensor. Maybe you just need it cleaned?

    I cleaned out the dust from the inside (best I can). I only have the one lens so I can't see if it's in the lens.

    One thing I've noticed. I only see it if the aperture is around the f/11 f/16 mark (f16 being the highest it will go).

    Would that sounds like a lens thing. I'm gonna do another clean tomorrow once I got some good daylight and try it again.

    If you take a photo of a blank piece of white paper does this 'scratch' show up? If so, can you show us?
    What shows up on your photos? Is it a line? or is it a little 'spot' or 'blob' ?

    And also, are you sure you are looking at your sensor? Most people have no idea where it is or how to make it visible. Taking the lens off the camera does not reveal the sensor for instance.

    I'll get photos up as soon as I get kids settled. I'm looking at the peice that you see after you open up your mirror (mirror lock). It's the peice that is on the bottom when you are looking in.

    be back asap

    Well. Here is a photo (cropped) from last night. There are several of these.

    I did some more on white this morning but nothing. I tried different f/stops and focus'. I don't know. Happy in a way but I still can't figure out what would make lines like these?

    And should I still be concerened with my scratch on that peice I tried to explain above...(if you understand it).

    Thanks for helping out! I know I should know more about this..



    Just reviewed this photo, if it's not clear enough I'll post full in flickr.

    I would take it in for cleaning, that looks like a smug of something on the sensor. Cleaning sensors is for the brave and trained.

    I guess it’s possible that you have a scratch, but I kinda doubt it unless you’ve gone into mirror lock-up to do some cleaning yourself. Something would have to come in contact with the filter or coating over the sensor in order to have created a scratch.


    Set your aperture to f/22, open a blank doc with whatever word processor you use, and get about four or five inches from the monitor to get a shot that will really show what kind of problem you might have. Don’t worry about focus. Try it with more than one lens.

    Have a look at this link to get an idea if cleaning it yourself is something you might consider:

    Your sensor is behind your shutter curtain. To see that you need to use Mirror Lockup but then also hold down the shutter button when on bulb or on my camera there is a 'manual' sensor cleaning option in the menu which opens the shutter curtain so I can see the sensor.

    On the bottom of the camera under the mirror is a black looking rectangle which is not the sensor.

    I'm highly doubting you have a scratch on your sensor somehow unless someone got in there and tried to clean it badly. Even then the scratch is on the layers of glass (UV filter) that sits in front of the sensor.
