Reoccurring Spot in My Photos

I have a new Canon 20D and I am noticing a spot in my photos. I've noticed that they show up with both of my lenses, so it's not the lens.
What can I do to remove that spot?
Thanks in advance!

  Best-case scenario: You've got a piece of foreign material (dust, lint, etc.) on your sensor chip. Read your manual carefully, and follow the instructions for cleaning the chip. If Canon doesn't recommend cleaning it yourself, abide by what they recommend. Be careful with it.

Worst-case scenario: You've got some dead sensors already, but I would imagine that a new 20D would be fully covered under warranty if this is the case.

  Check out:
for discussions on cleaning your sensor (yes, it does sound as if you've got a speck of dust on your sensor).
At first, try and blow it out with a good blower. If that doesn't work then you'll have to clean it. DON'T ever touch the sensor without your knowing what you're doing - that's why you might want to check out the discussion forums on this issue.

  I was also getting spots on my 10D, (usually round)in some of my photos as well. Once I cleaned the sensor, the spots were gone. Read the manual on sensor cleaning.

  I have the same thing on my 300D. At first I thought it was lens flare. Kinda round, not very sharp - almost like a water drop on a negative. I've had the camera for a year and I can count on one finger the number of times I've removed the lens. Should I expect this regularly?

  John, what kind of lens do you have on your 300D? Sometimes the push/pull telephoto lens can acquire dust because of the movement of going in and out. Also, sometimes second party lenses may not be as 'good' as Canon lens but that's just hearsay - I'm not sure it's ever been proven.
I use a Sigma 18-124 mm as my walkabout lens and have never had any trouble with it.

  it's the standard lens that came with the camera - a canon. That's good info though as I am looking for another lens.

I will try cleaning it. I suppose once a year isn't too bad.

  I am wondering what's up with the new Canon 20D. I bought a new 20D and the first day I had it, it had the same spot problem. The spot showed up on all my pictures. I was able to exchange it, but it cost me $45 in postage. Now, the new camera I received in exchange has a problem with the shutter sticking. I had Canon load the new firmware update and it hasn't fixed the problem. Otherwise I love the camera.

  See my posting above - go to
and do a search. There has been quite a bit of discussion on the issue of locking.

  This is why I shoot Nikon. ha ha ha.

That sucks about the shipping charges and then getting another problem. I'd rather have the old one back and then clean the sensor myself.
