I have only had my D7k since January and have taken very few images. However it seems that my sensor needs cleaning. Does anybody have a Step by Step Guide on how to clean the sensor on the D7K? I do have the sensor cleaning option turned on at start-up, and thought this would be the end of my sensor cleaning woes (my old D70 needed quite a few sensor cleans. The cost & inconvenience of having the sensor professionally cleaned in Australia seems prohibitive). I already own a Giotto Rocket blower and plan on using that first.
There's already a long and involved thread on this topic concerning the D7000. Page down a bit and you'll see it. For some reason, this camera's sensor seems to be a dust magnet as I have already had to clean mine twice in the 3 months I've owned it. My D70s was a lot more dust resistant than this.
In any case, I have come to embrace products from VisibleDust.com They work well for me, so they are well worth the investment.
Thanks for the advice. I have tried the "Rocket" blower. Unfortunately it had no affect, so I'll have to try wet cleaning with sensor swabs. (NB.Thom Hogan's book on the D7K also has sensor cleaning advice, similar to his often updated article on sensor cleaning)
Definitely try the Rocket blower first - the large one - it has helped me out tremendously quite a few times. I've tried cleaning a sensor once, it is a very meticulous and difficult task, well, at least it was for me. Once you start doing the cleaning, you have to complete it, and the results may not be what you expect, if you don't do it just right.

I had noticeable dust spots in some of my images so I followed Thom Hogan's advice and took a photo of a uniformly light subject (in my case a cloudless blue sky) at f22 and 100iso. The dust spots were very easy to see without any post processing.
My own test for spots involves 100 ISO, smallest aperture I can dial, one meter away from a poorly lit white wall, at home. Focus for infinity, exposure time gives me around two seconds, and through this time I move the camera in circles, to make sure it is impossible for the slightest imperfection on the wall to print. Only dust will show, and very clearly.
Sometimes the rocket blower isn't enough to get the largest ones out, so I repeat until the major offenders have been blown away. Total time for the operation is less than ten minutes. The end result is still not perfect, but more than adequate to shoot real-world skies.

I again tried the rocket Blower, this time coupled with a Nikon body cap with a 9mm hole in the middle. I placed a 10mm long rubber sleeve over the base of the shaft on the blower to prevent it getting too close to the sensor, then puffed the blower numerous times. This still wasn't a success , so I had to resort to wet cleaning. I now have a clean sensor, thanks to Eclipse Solution and Sensor Swabs. The whole process has given me more confidence to be able to clean my sensor whenever it is needed. Thanks again to fellow Nikonians for friendly, non judgmental help.
