Leonard Shepherd: An "interesting" video - but is the video reliable?Every time the mirror lifts it blows some air forward, creates a mini vacuum and some air gets sucked back. Then when the mirror falls the air currents get reversed.If there is dust in the mirror box or on the rear lens element or even if the lens is not airtight (the 50mm f1.8D is not and does not have a lens flange gasket) - maybe this video is not reasonable evidence the camera had a defect - especially if there was a lot of none camera body induced dust.Going further the left hand side of the video has uneven lighting - the video showing the test set up does not - if anything the light level is higher on the left - and is clearly both uneven and darker in the video.I suspect a "troll video" with less than 1 out of 10 for credibility.
The reason for the difference in lighting between the before and after shots is the heavy curves adjustment done to bring out the more faint dust spots.
I have posted the unaltered photo to flickr: http://www.flickr.com/photos/kyleclements/8211640921/sizes/k/in/photostream/
You are welcome to download it, put on some curves, and see for yourself that what is shown in the video is, in fact, the same image.

a first statement of Nikon . . .
It had better be covered under warranty.
The email suggested that I bring the camera in for cleaning and inspection, no need for pre-approval or authorization, they apologize for these problems, they strive to repair all items as quickly as possible, etc.
No mention of charging for this service was mentioned in the email.
jtan163: My D7000 seems to be about the same. Clean the sensor and 5 shots later.....spots.
I've spent a lot of time with a few D7000's and never had an issue with dust or oil spots. This is precisely what lead me to believe the D600 dust issue was overblown, run out, purchase one, and do this test.
ImageAcquisitions: I'm curious why Dpreview hasn't done a full blown out review on this issue. Especially after seeing this clear example of an issue.I wonder if:1. dpreview is handling Nikon with kit gloves to avoid any conflict with them so they can keep getting free equipment to do reviews. Sure, they can talk about the feature differences, but exploring this potentially defective product issue may be what they are contractually not able to do? What did the article say above "Expressed concerns" Asked nikon for a comment? Nice soft approach.He, do a full blown out review of this particular issue - don't wait for Kyle Clemens to explore it. Use your professional staff, paid no doubt, to do a full blown out investigation of the gear.
2. Nikon isn't ready for a multimillion dollar product recall. All the elements are there for a class action lawsuit against Nikon to a) Stop continually selling the defective product (maximize profits); preying on customers unaware of the situation who buy it anyway.
"The video here was done by who? Is that guy affiliated with DPR? Or is he a camera enthusiast."
I'm just a camera enthusiast.
I didn't even have an account here until I saw that my video was posted.
Dan DeLion: I received my D600 two days after its release (ser. #3007970.) It now has over 4000 exposures and probably 200 to 300 lens changes. There's not one speck of dust on the sensor. I checked it yesterday with the mirror up, a high intensity lamp, and a magnifying glass. Remarkable handling and splendid images. - The camera has already paid for itself several times over! Did this fellow turn his camera on and off (for sensor cleaning) during his thousand exposures?
Nope. I was using the interval shooting option to make this timelapse.
I did turn the camera on/off after the first 500 shots, and select the sensor cleaning option from the menu, so the sensor went through 3 cleaning cycles in the middle of the video. Didn't seem to make much of a difference, unfortunately.
When I brought this issue up with Nikon, my response from the Nikon Service center was incredibly prompt, polite, and accommodating.
Can't wait to see how this thing works after the cleaning.
