If the dust does not affect the images, leave them alone.

You can send it for servicing or try to DIY open and potentially ruin it.. Then give it 2 weeks and it's back yay!

If it doesn't affect the pictures, dust is inevitable, let it be.

Dust or fungus? If it is dust, and if it don't affect your picture, don't do anything... because even when you managed to clean it off, dust will still get into your lens sooner or later... because the place we lived in is not exactly dust free.

If it is fungus... then I would take it down the service center or some third party shops to have the lens clean. Do check the lens carefully when you get it back. if there are back focusing or front focusing issue, then do a calibration on the spot.

Dust inside lenses is very normal, you are not living in a dust free world. So can wait till it shows up on the photos than start worrying about it. but that probably need a thick coat of dusk cover up the lens.

Don't worry about the dust. Won't affect anything at all. The one that we worry more with is usually fungus. That one more jialat over time.

Dont worry ;) , even new lenses will have some sprinkling of dusts inside from the factory. Some lenses by design aren't fully sealed, also zoom lenses suck in outside air when the lens elements are moved so the dusts particles get in over time. The dust particles will not effect your pictures.

If you use a prime / zoom lens for many years & it is very dusty internally you can always sell it off & get a new lens or send it to the service center for a cleaning.

Just by vacuuming it externally, I am afraid no.

On some lenses the covers & rubbers can be removed without much difficulty. There are open slots within the lens assembly. One can use a vacuum cleaner to remove some of the internal lens dust this way.

The canon 100-400mm is such a lens. Just remove the covers & sealing tapes. Apply vacuum to the open slots to remove the dust.

Don't. Keep shooting. Stop worrying.
Did you manage to locate the dust from the lens on your pictures? :)

Do a search on dpreview. Some successful cases.
Ok. Let me explain.

First, not all vacuum cleaner would help. Vacuum cleaner being used to suck dust out of the ground in your home is going to be one of the dirtiest and dustiest thing around, unless you buy one just to clean lens. Then... look at one of the example in dpreview, that fella tried to vacuum clean all over the lens, don't work, you need to place the vacuum clean suction mount right where the rear optic element was, then suck.

One wrong move or the suction mouth was not of that size, it might knock into the element and damage it. Secondly, if suction was too high, there might be problem with knocking the element off alignment.

So, when I ask if you are joking, I really mean it. If not, please come up with more details on how it could be done, this is important, because as far as I see it (and don't mind me being a bit of a paranoid), it is too risky and not worth the effort or risk to remove dust that would in the first place not cause any problem to the IQ of the picture, and if it was large enough to cause problem, you probably wouldn't get it out without dismantling the lens... and if it was fungus, there is no way of getting rid of with vacuum cleaner.

Dust inside lenses are common and normal, as long it does not affect image quality, than shouldn't be worry too much about it.

getting too paranoid on dust issue, it is sign of OCD.

Thirdly: air needs to get into the lens before being sucked out at the rear element (and hopefully taking the dust out on its way). That's a good opportunity to get more dust into the lens :)
