Sensor scratch

[Mad Aussie]

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

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.

Looking at your photo above I think that is just dust. A strange pattern indeed. Just above and to the right of your black square is a small dot that is typical of a dust spot on a sensor. I have several on mine at present and need to clean it.

Whew. Alright. Sounds like good news.

I get the usual dot ones. Pain in the arse they are, if they are big blobs, first think I look at is the front of the lens - but this was wierd! Heart froze for a second when I went through photos..

Thanks everyone for the replies!

[Mad Aussie]

So you weren't physically looking at your sensor then?

[kat]

I had the mirror lockup on by going through the manual and pressing shutter button. I was just looking at the next thing you see. Like a board that changes color in different light. I assumed it was the UV thing...

[kat]

Okay. So I jsut read this for my camera... "This then allows you to raise the mirror and the shutter curtain, and reveal the low-pass filter for cleaning". Now maybe it's this low-pass filter I am seeing???? Gonna do some more looking around but having a hard time. You'd think there would be one photo on the internet on what it looks like inside my camera!!!!

That is the low bypass filter you see. Don't sneeze on it I suspect you have a smug of dirt on it.
