What causes this??

I picked up an old 1D on ebay, the seller is a photo store, so they do have a warranty, but I want to know the reasoning, and if its an easy fix, if not I am going to be pissed that they sold this to me.

Here is a picture of my ceiling, so you can see the spot.

 

dust on something in the camera

 

I figure that, but what is the something? Its not on the mirror.

I guess I should ask, is it an easy fix? Or should I send it back and ask for a full refund?

EDIT, thanks Bitter for the link.

 

I picked up a sensor cleaning kit, the camera shop was going to charge $25 to clean and the kit was $30. I can see the spot on the sensor, and I have tried cleaning a couple times, it is not coming off, is that normal? I would think if its dust it would easily come off.

 

At this point, I would spend the $25 to have the store clean it. This way if they mess it up, they have to fix or replace it. You don't want to be scrubbing your sensor with a scotchbrite to get gunk off.

 

No I wouldn't, Is that what they would do?

 

No, I was being figurative...I forget about how tone of speech doesn't count on the internet. My point was that if it's on there pretty good, I wouldn't go scrubbing to try and get it off.....if it's not just dust that can wipe right off, I'd leave it to the pro tech's to clean it off safely.

 

You might want to down load some custom curves and load them into your camera because you can sometimes get a green cast in the shots but you should be well pleased when you see what that camera can do
This is a 1Dmk1 shot

 

Thanks, not sure how to do that, but I will look into it. You are refering to the original 1D, I have never seen anything marked mk1, but I guess since its the original it didnt need it?
I am debating on keeping it, I am not wild about the quality that the preview screen it, its hard to get a good idea if the picture turned out.

 

It's worthwhile learning how to clean a sensor properly and getting the proper gear, if you're serious about your photography. Every DLSR wil lget dust on the sensor at some time or another, and if you have to pay to get it cleaned every time then the cost will add up over time.

I suggest researching the 'copperhill method' of sensor cleaning (or wet cleaning). Whatever you want to call it, it involves wiping the sensor clean with the appropriate solvent. you can buy some stuff called eclipse fluid and lint-free cloths called pec-pads to do it, though they are expensive. The eclipse stuff is just methanol - it evaportes really fast so doesn't leave smears from wiping. Do not use methylated spirits.
