red dot on my digital photos

If you look closely at every "blown-up" shot, there is a small red or pink glowing dot towards the top-left.

These were all shot with my Canon EOS 7D.

The dot always seems to appear in the same place.

What do you think the problem could be?

Thanks

I suspect that you have a defective area on the camera sensor.

Here are a couple of threads dealing with "hot pixels" which may clarify the issue for you.

The camera is pretty much brand new. Is it fixable? Is it just a matter of cleaning the insides?

Cleaning the sensor will fix it if it's just a speck of dirt, if it's a damaged CCD sensor the sensor would need replacing. Is it under warranty?

Sensor cleaning for your Canon EOS 7D camera:

Maybe safest to get a Canon dealer to do the job.

No cleaning it will not help. Dirt on the sensor shows up as a black blob with soft edges. The fact that this is a bright color indicates that it is a bad pixel on your sensor.

If it is in warranty, then by all means have it fixed. If not it will be something that you will have to live with using work arounds like vallis has suggested.

Happens to all of us sooner or later. Hot really a big deal, especially being towards the edge of the sensor. If it was smack in the middle, it would be a bit more of a problem.

Correction, I meant to say that cleaning it will not help in the sense of removing any dirt or debris. Cleaning in the sense of mapping the bad pixel is a good idea.
