Thank you, well done.
Now I think that it would be nice if there was a sort of standardized way of looking for dust spots! Yes I know the blue sky f:22 or the white wall f:22 at 100ISO. They are both OK. Are we talking of no dust spots when they are invisible without changing anything to the photo,or do we talk of dust in LR5beta "Visualize Spots" with the slider to the right. where every little spot becomes visible of that very same picture?
When you move the slider to the middle the spots are dissappearing.
So the slider should be at about 50% to represent our blue sky f:22.
Now what about these tiny little spots that are there, many of them.After wet cleaning ,they diminish but it's really hard to get it totally clean. The rocket blower is not of much help it only deplaces the dust.
My sensor after cleaning by Nikon still had about 18 spots,(hundreds before ,a few became visible at f:8) Now (500 shots later) there are more than 100 spots, but still nothing visible at f:22 blue sky.
So I wondered how other sensors looked like.
I tested my D70 ,D90 and a Canon 5D MarkII,and a Leica M9 of a friend of mine.
Well they all had comparable number of tiny little spots with the "Visualize spots" -slider to the right of LR5beta.
If you want to find dust you will find it! But if you don't see it in your pictures, don't get nervous, because your camera is a D600 and prone to dust. It's a fantastic camera, just enjoy it.

A long explanation, to resume:
When we talk about dust, I would like to be sure we are talking about the same dust.

The Arctic Butterfly kit comes with a lighted loupe that will allow you to see and magnify the sensor for close inspection. www.bhphotovideo.com/c/product/838868-REG/Visible_Dust_66...
I think we're talking about the obvious spots that will appear in every photo, especially on featureless parts of the photo that interfere with the scene and those that start appearing even in the wider apertures. If you start seeing lots of little dark spots at f/4 - f/16 and they keep coming back after a cleaning (and you weren't changing lenses in a dusty environment frequently), it's safe to say you might have a problem.
For example this is what my sensor looked like after Nikon service cleaned it, after I took about 600 shots with a prime lens attached:

Sometimes it may take two or three swabs to get it completely clean, especially the first time.

When was the last time you cleaned those sensors? I also checked my D7000 and D40X sensor. The D40X had never been cleaned so I checked:
As expected it was riddled with spots. I tried cleaning it, but was completely unable to remove those located in the center, the tiny little ones if you look close at the photo. It's as if they were welded onto the surface. In everyday shooting these didn't bother me. I didn't even know they were there. I also checked the D7000. That one had probably three cleanings within one year since it went to Nikon service for unrelated issues. Looks like I had an issue and didn't even know it:

Agreed. If you can't see the problem in your day to day photos, don't worry about it too much. As can be seen from the videos and articles provided, DSLRs of all types are prone to dust and should be cleaned once in a while. The D600 seems to suffer from this more than any other, but that doesn't mean it can't be solved or that it is a permanent problem.

I have had an D600 soon after it was available and have now over 9500 actuations on it. I have been dealing with the oil spot / dust issue from the beginning, and in my experience only wet cleaning has helped before, but even with it, it was really difficult getting the sensor totally clean and not just moving the oil/debris around to the edges etc. and/or leaving residue from the cleaning chemicals.
Recently I dared to try the "scotch tape method" described here: photo.net/casual-conversations-forum/00Z8oD and was amazed, I got a completely clean sensor (and wiewfinder screen too) in less than 10 minutes, basically "it just works".
For people worried about what is left on the sensor from the tape:
a) I have not seen any evidence of anything being left from this cleaning method, not in regular pictures, test shots or visual inspection of the sensor. All that is left, is a sensor that is as clean as when it was new.
b) I figured, that if/when some residue from this tape method is left behind, I will clean that with the wet cleaning methods and chemicals. Basically rather use 5 minutes cleaning the sensor and getting 100% clean results, and maybe once every 6 months cleaning with chemicals if something is left behind from the tape, than wet cleaning my sensor every week with swabs etc. that usually don't result in 100% clean sensor anyway.
I'm not recomending it to anyone or taking the blame if you sensor gets totaled, but I can honestly say it will be the method I will be using from now on without any hesitation, it gets me results and I personally estimate the potential for permanent sensor damage etc. to be very low from this method, lower than repeated wet cleanings.

Also keep in mind that if you are using zoom lenses you will get more dust by the mere fact that you have some kind of suction effect happening when you zoom in and out. Pro zoom lenses with lens mount rubber seal ring minimizes this as well as using newer prime lenses with rubber seals.
Also changing the lens by pointing the body down minimizes the dust getting in the camera as well as a 1-2 second lens change switcheroo wherein you hold the lens you are replacing with next tot he lens mount and disengage the mounted lens and switch it in 1-2 seconds.
For those who think that film cameras never had dust, they did this is why some of them have felt pads and rollers on the film path. Large and small dust is everywhere (except maybe in Antarctica) and it is a fact of life.
I personally have always used the Nikon Sensor cleaning method and have had no problems at all for 8 years now:

Yes I use a lint free lens cleaning sheets that I double and I do not buy special sensor cleaning cloth/paper just optical lens liquid cleaners.

I'm not buing the "zoom lens pumping" or "lens change" theories, because they don't explain why the D600 would be aquiring any more dust than other cameras. What I have gathered is that even if this problem is not only a D600 problem the problem is at least much more serious with D600 bodies and there is something else than mere dust that's getting on the sensor.
So my personal conclusion (yours may be different):
1) There is some oil coming from inside the D600 mechanism OR some paint debris etc. breaking and getting on the sensor when the camera is being operated, not only dust from outside sources.
OR
2) There is somekind of design flaw in the D600 that causes it to collect more oil/debris/dust on it's sensor (whatever the source) and not be able to get rid of it by itself with it's own internal cleaning mechanism.
I also have had an olympus OM-D for about a year now and have changed lenses numerous times and locations and the sensor still requires no cleaning (I have zoom lenses on it too), but the D600 requires cleanings every week if I want images that have no spots in them, to me this is enough to prove that this problem is at least significantly more pronounced with the Nikon D600 bodies.

Keep in mind that I mentioned 'dust' not 'oil splatter', these are two different issues and yes the D600 and D7000 did and do have this 'oil splatter' problem.
Also an oil splatter behaves and looks very differently from dust specially regarding the translucent ring and more regular rounded and oval formations. This is not just a D600 issue since the D7000 had this (as well as other models Nikon and Canon) and most with problems have had their mirror assembly replaced which is what has been happening with the D600 being serviced as well. I am sorry if you misunderstood me.

I think the oil "splatter" issue is the more serious one and the one that is more closely specific to this particular camera, so I assumed it was the one being discussed here, my apologies if this discussion is more general and related to regular dust that all cameras at least possibly get sometimes.
I have been waiting for some news, that EVERY D600 that would be sent to repair(because of sensor dirt) would get some new mirror box or other part that would 100% fix this issue, but this probably has not happened yet? I haven't seen the point in sending my own camera in yet before it will result in some parts being changed or more "heavy" cleaning being done inside it(to remove oil from the source), since I have been reading that usually all Nikon does is a simple clean and then returns the camera back to it's owners and the same problem keeps occuring a few days later..
