5d III spot on sensor?

What could cause the following spots? Is this the sensor going bad, or just a sign my sensor needs cleaning?

The spot is in the top left corner of the portrait, and upper middle right of the landscape. (Dark spot in the sky on both).

Dust/dirt. Needs cleaning.

Start with mirror lock up and a rocket blower.

A giant dustbunny, unless you live in Rosswell...

Start with a Rocket Blower and if it doesn't move buy a wet cleaning system

Copperhill Images is what I use.

Thanks for the help. I didn't even have to use a rocket blower. I just manually activated the sensor cleaning function inside of the 5d III, and everything is good. I guess I panicked over nothing. Maybe somebody else can learn from my embarrassment.

Set the auto cleaner to run every time you turn he camera on and off. This way dust doesn't stick over time.

It is set to run every time. I just haven't physically turned my camera off in the past few days. I guess I need to learn to turn if off at the end of every shoot.

For goodness sakes get a rocket blower though. Glad the camera removed that dust, but a rocket blower, not just for the sensor is so good you'll wonder how you ever did without it. They are like $10.

Either that or check and see if a UFO was in your area..

get a rocket blower, super useful. I tend to get a lot of dust on the sensor as well, and rock blower to save the day. Great on dusty lenses too.

Ok, I have just ordered a rocket blower. So is it just as simple as locking the mirror, and blowing the dust away? Any danger in messing anything up?

Thanks for the help.

No. MLU does not open the shutter. You need to use manual sensor cleaning. It is simple to use though.

Yes, manual sensor clean locks up the mirror and shutter until you turn off the camera. Hold the camera facing down when you do this and use the rocket blower from below do any dust falls out.

The only thing that can go wrong it that you put the end of the blower too close to the sensor and then bash it into the sensor as you squeeze it. Yes, I actually did this with my T1i - left a 'gunk' mark, but actually no scratch. Still it was a heart-stopping moment and not one I recommend. Just don't jam the end of the blower into the mirror box, you don't need to get it close to the sensor, more like just getting dust out of the mirror box area.

In any case I think you will find the blower very useful, even if you don't use it on your sensor (I would give the 'sensor' a few blasts every once in a while though).
