It's pretty annoying when you spend a load of cash on a new toy and the manufacturer hasn't ironed out all the kinks! It seems the mirror of my Nikon D600 is spraying lubricant on the sensor, as the spots visible here are not dust and have increased in number over time.
This shot is completely untouched other than being converted from RAW to JPEG. It is a worst case scenario shot, blue sky at f22, taken to illustrate the extent of the problem.
I took the camera to the shop today, they wouldn't replace the body, so I had to send it in to Nikon for repair. It will be gone for about 2 weeks after only 10 days of use. I am glad I didn't sell my K-5 (just most of its lenses).
It's a real shame as I was just getting used to the camera and liking what it can do. I'd stil recommend this camera, but I'd wait a year until they have fixed this quality control issue.
This is what I get for breaking my rule and buying a new product Day 1.
Oh well, I have got some spots to remove in Lightroom for the next batch of Kusatsu pictures...
RE_BEAM ROBOTS: Taller de construcción de robots

After dropping my XTi face down into dirt (more on that here) my sensor got really filthy . Many shots with aperture smaller than f/13 had to be touched up.
My Giottos Rocket Air blower got about 50% of the mess out, but the filth was still unacceptable.
So I decided to get wet cleaning a try and ordered ordered Type 2 cleaning swabs and Eclipse E2 cleaning solution made by Photographic Solutions. After five tries, this is as clean as I could get it. I think I can do better with practice.
Would you consider this clean enough?
How clean is YOUR sensor? Let's see some shots!
To get your sensor dirt to stand out the most, put on a 50mm lens or longer, set the aperture as high as it goes, manual focus to infinity and take a picture of a white piece of paper from a distance of 20-30cm (8 to 12 inches). No need to worry about camera shake, the dust on the sensor shakes with it :)
Now lets see them.
Comments welcome.

In a retired jet at Sandia, Dennis Roach and Ciji Nelson prepare Structure Health Monitoring (SHM) Sensors.
The Comparative Vacuum Monitoring sensor is a self-adhesive rubber patch, ranging from dime-to credit-card- sized. The rubber's underside is laser-etched with rows of tiny, interconnected channels or galleries to which an air pressure is applied. Any propagating crack in the materials under the sensor breaches the galleries and the resulting change in pressure is monitored. The sensors are made by Structure Monitoring Systems, Inc. (SMS) of Australia, are inexpensive, reliable, durable, and easy to apply. They provide equal or better sensitivity than is achievable with conventional inspection methods. Besides aircraft, SHM techniques could monitor the structural well-being of spacecraft, weapons, rail cars, bridges, oil recovery equipment, buildings, armored vehicles, ships, wind turbines, nuclear power plants, and fuel tanks in hydrogen vehicles.

Just thought I'd share this little tip with everyone on how to check to see if you need a sensor cleaning. I noticed a couple of spots in the top right corner of some of my photos and thought it was the lens at first. After switching lenses and seeing that the spots were still there I thought I'd investigate sensor cleaning procedures.
I found this site:
www.cleaningdigitalcameras.com/inspecting.html
that explains how to take a test shot (seen above) to see how much dust is on your camera sensor. As expected I have a couple of dark spots in the top right of mine ... and a bunch of others I hadn't noticed in my photos.
It's been just over a year since I got my camera so I'm going to send it in for a professional cleaning which will hopefully get rid of 99.99% of the dust.
Hope this tip proves helpful.
At NETL, Thomas Simonyi, left and Stephen Beer use a thermogravimetric analyzer to analyze heavy metals to determine their suitability for making thin-film sensors for natural gas.
NETL is teaming with Carnegie Mellon University and West Virginia University to develop sensor arrays that can respond to rapid changes in fuels gas composition. The ability to detect and respond to changes is increasingly important because of the anticipated increased usage of liquefied natural gas in the nation's pipeline of the system. The technique for sensing hydrocarbons such as methane (C1), ethane (C2) and propane (C3) involves characterize their crackling behavior over catalyst materials. The technique developed by NETL researchers differentiates the activity of platinum catalysts with C1-C3 gases from thermal cracking.

This is a full-sized crop of one side of the Wii "sensor bar" from the last picture, which you should go look at first. What's neat about this is that those lights are completely invisible to the naked eye, because they're infrared, but the CCDs on my digital camera pick it up somehow. Just another reminder that cameras and eyes actually work differently. :)

Here you can see the D40x sensor with its IR blocking filter removed. Without this filter, and without an IR passing filter, the D40x now records both IR and Visible light.
Do you clean your own sensor? I bought the MARUMI Low Pass Filter Cleaning kit which I will attempt to use next time I have dust on the sensor. Getting tired of having the camera shop do it.
Lighting details: SB800 on camera bounced off ceiling. SB600 handheld pointed at a 1m diameter reflector on the floor angled to point to me. Triggered with Nikon CLS.
For those who've wondered at my probably annoyingly often references to the damage to my camera, here it is in all its glory.
The only reason I'm sharing this is because of the amazing flare my 10-20mm produced here.

New safety installation at the industrial railway of Stadler when crossing the main road. This system operates independently of the normal train protection. If a shunting loco stands above this sensor, the system can be activated by a smartphone app. Staad, Altenrhein, Switzerland, March 7, 2015.
This is the Oxygen Sensor, also called Lambda Sensor or O2 Sensor. It's screwed into the exhaust crossover to sample tailpipe emissions, and send a signal back to the ECU. For this project it's not necessary to remove the sensor, which is good since they are often corroded in place.
There are 4 wires inside the black wiring sheath;
2 white for the sensor heater
1 grey for sensor ground
1 black, the signal wire - the important one for us
