I am having problem with dust on 5dmk2 , not sure if Dust removing system works on camera , didn't use camera many times but there are many dust spots , visible in video at f16 apertures. with pictures there is no problem removing it in photoshop.

i tried Giottos blower , but it didn't work , tried sensor cleaning swab , and things are even worse now.

in past i didn't have to much problem with old 5D as i use mostly

what about you ? is it possible that dust removing system on camera doesnt work ?
 
Mine seems to be OK, but that hardly helps you...

Try to investigate a bit more. If you never shot much above f5.6, dust may have been there always.

Can you see it on sensor? If not, you might suspect lens as well. Do you have the option to check lens on another camera (at f22). Also, does dust spot remain in same place if you switch lens? Basically, swap some things around and see which piece of gear the dust follows first.
 
Dust on the lens will not be visible in the viewfinder or in photos except in the grossest cases - e.g. big gobs of mud on the front element. I think you can rule out the lens explanation.

I'd use a blower on the dust to see if it can be moved off the sensor. Perhaps also use a sensor brush. If these don't work you may have to do a wet-cleaning.

dust is on senzor for sure , after i tried swab, dust just moves to other places , and there is lot of dust now , more than before i tried to "clean" it.
 
If you are not comfortable with wet cleaning, I think you should pay to get it professionally cleaned. There is always "factory" dust that appears in new Canon cameras. After a few cleanings, it should be all done with.

If you can do your own wet cleaning, that would be best, but it is a little scary at first and if something goes wrong you are out a camera. Spend a few more bucks and get it cleaned by someone good.

i used sensor cleaning swab (not sure if it called wet cleaning) today for first time , it does looked a bit scary , but i did it even few times and each time dust moved from one point to other , not close to perfect clean , will post examples.

i wanted to clean sensor today as after tomorrow my wife and i am going to ski vocation and wanted clean sensor for photo and video capturing.

thank you all!

here is how it was before "cleaning" :



and after:

 
When you said 'used sensor swab numerous times', do you mean that you used numerous clean new swabs, or just used the same one over and over? You should not re-use swabs after they've touched the sensor, and will need to use a clean wet swab each time. It sometimes takes using 2 or 3 wet swabs to get almost all the dust off, and even then you may have a couple of small spots that just move around and won't come off.

I've had that exact problem before after going to Phoenix, AZ to do some shooting. Some dust is just extremely stubborn, and it really requires someone who knows exactly what to do to get it off. I would definately suggest that you take the advice of the people here recommending that you take it out to get cleaned.

I'm in Toronto, and always take my unit to Sun Camera Services to get it done. It costs me $60 CDN, and I'm am extremely happy with the results.

i used 3 swabs , each time taking new one, but still dust is there as you can see in examples that i posted.

Thats a lot cleaner than my 1DS-mk3 and I mean after being cleaned by Canon Irvine. I have about 6 visible spots at f22 and before using auto levels.

Be careful of these new self cleaning cameras, the top filter is very fragile and easy to break, and very costly to replace.

I'm of the mind that you're expecting too much too quickly. I suspect some cameras come with more dust than others, and the dust within makes its way to the lens chamber as the camera is handled. At least, that's how my first two months with the 5D felt.

If you're not intimidated by doing your own cleaning, and can avoid getting frustrated, I'd suggest you give it another go. It's when one gets frustrated that most accidents occur in this task. I also recommend, besides a blower, the Dust-Aid adhesive and wet cleaning approach.

Here it looks like you either mainly moved the dust around, or there's a lot more in the chamber that occurred right after your cleaning. Practice gets better results over time, while it also becomes less the chore than just a routine.

It's not a bad idea to have it cleaned by another. . . all just FWIW.

I had the same problem. I send the camera to a independent professional to try to clean but he said the dust is under the low-pass filter. So, to confirm, I send it to Canon. They said the same but, in Brazil, a camera bought abroad does not have Canon warranty (I bought it in New Zealand). The cost to disassembly is so high it does not worth to make this repair. So I have to deal with that dust or buy another camera.

Are you sure that you've used the correct swab for full frame sensors? I'm asking you this because from your examples I saw that all the dust was concentrated on the bottom of your sensor. This happens when you use a smaller swab or when your pressure is not equal on the whole surface. I don't say you have to put more pressure, no sir. Just keep the pressure constant on the whole line of your swab. Did you use Eclipse or swabs have already some solvent? Just two-three drops of Eclipse should be enough on dry swabs.
 
I had 'factory' dust on my sensor as well. Be sure to use the correct sized sensor brush/swab, I use Visible Dust gear, and it always works. You should try to clean yourself - professional services are nice, but they're not available when you need a cleaning in the field....

How on earth do you expect dust on the lens to appear on the image?

Precisely which Canon lens has an intermediate focal plane? That is the only way that you will get the lens to collect dust that can be imaged onto the sensor, but I don't know of a single one in Canon's inventory - or any other third party consumer manufacturer.

Unless someone can cite an example, and it turns out to be the lens that the OP is using, then lets get rid of this particular piece of confusion: IT ISN'T THE LENS.

I think you are on the right track. Be patient and only ever apply the least amount of pressure needed.

Use a combination of the swab and blower (better if you have a nylon sensor brush as well).

Just be patient. I've had occassions where I've used 5-6 swabs in combination to the blower and brush.

Seemed like I was only ever moving the dust around the sensor. But finally got there.
After each clean, I turn the camera face down before switching off the power.

Gotta believe in something....believe I'll take another photo...

Frankly, that is disgraceful and Canon should be shamed into fixing this. Dust under the low pass filter is clearly a contamination problem at the factory and, irrespective of where you bought the camera, it is Canon Japan's fault! No camera leaving the Canon factory should have this type of problem, irrespecive of whether it is destined for USA, Brasil, India, Turkmeniestan or even the Moon on a Japanese spacecraft! This is a manufactured defect, and if Canon Brasil acknowledge that then they should be taking responsibility for it.

Warranty repairs may be a local agency responsibility, but this is a manufacturing defect - it clearly, by Canon's own admission, came out of the factory that way and Canon QA wasn't good enough to spot it.

I don't know your rights in Brasil, but if it was me in the UK, I would be filing a small claims action against Canon Japan. At worst, they will action their local agent, Canon Brasil, to respond - which means they acknowledge them as responsible. At best, they won't respond and you'll win the case by default - with potentially much larger penalties for Canon Japan to face.
