Sensor scratch

[Mad Aussie]

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!

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

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...

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.

For all intents and purposes Kat ... that is the sensor. So you were looking at the right thing.
The sensor has some fine layers of glass over them (the filters they talk about) and the dust gets on those.

Okay. I'm quite sure there is a scratch on it. Something must of gotten into it. I usually never open up the mirror unless I know there is something in there and blow it out or use my little static brush. Maybe there was something on my brush!! I don't know..either case, I don't see anything right now on my photos but will keep an eye on it!

I'm thinking coincidence between the scratch on the sensor and dust in my image (for now anyways).

Hmmm... This doesn't make sense to me. The low-pass filter is normally made out of something akin to mineral glass; in other words, it's as hard as the hubs of hell. Scratching it should take a LOT of effort. What this looks like to me, at least in that one image is a smear of some sort. I would buy a wet cleaning kit and try that before you do anything drastic.
