Oil residue. It does not appears as dust and is not detectable with a casual visual inspection.
You local store is manned by a bunch of bozos.
So Nikon is not the only one to F that up? I remember back a few years ago a lot of people had oil problems with the D600 was it?
I knew there had to be something funky about the OP's repair place. I did not think of the oil issue since he has a Canon and I've never had oil on my sensors. Great you figured it out, now we all know.

Maybe they need new glasses. From the examples you showed, sure looks like a dirty sensor to me! BTW it is not so easy to see the dirt on the sensor. IMHO sensor cleaning should cure your problem.
Rongnongno suggested oil spots not dust, and that makes perfect sense to me, and if so the repair guys were incompetent.
Remember that if there is dirt on a lens it will not show up as spots on an image because they will be too out of focus.
So did they clean it or just look for dust? Clean it with a Q tip if it's dust it will be gone if it's oil it will smear and needs to be cleaned with a swab.
Have to agree with Ron & Bill. I've removed the occasional oil spot off my 5DIII and they look exactly like that. Dust seems to be more translucent when viewing on pictures.
Get your money back Linda and don't return to incompetence.
Thank you all for your time and suggestions. Much appreciated!
Are you sure it's not on the mirror?
Sorry, duh. If it was on the mirror it wouldn't be in the picture.

Bought this T3i "back-up" in January, new. Bought a used 70-300 mm lens at same time, and didn't remove from this camera body for at least four months.
Was very disappointed to see sensor dust after such a short time. Took to local camera store for cleaning yesterday; they said they couldn't find any dust on the sensor!
Here are test shots. All at f/22. I ran the jpg's through a Nik Color Efex "detail extractor" filter (didn't notice they'd changed setting to jpg-only, so I didn't get a raw file). Thanks for any input/insight/advice.

That is sensor dust. Take it somewhere else.
It looks like sensor dust to me. But they are probably very small particles which might be difficult to see when looking at the sensor. With your camera's battery fully charged, lock the mirror up and examine the sensor, with a magnifying glass if necessary. Try cleaning it with a bulb blower; you may be able to find one with a soft brush. If that doesn't work, wet cleaning may be necessary. If wet cleaning doesn't work, there may be a problem with the sensor; when in doubt, send it to a reputable repair facility for checking and cleaning. DO NOT use "canned air" or compressed air from any type of tank or reservoir; use only a bulb blower made specifically for cleaning sensors.

THAT should have been done by the bozos in the store, not the client after cleaning.
