Hi Jean:

Does that mean that the mini dome is out and will not work with the 8-15 on a crop camera?

Thanks,

Hi Ehanauer:  I have two D7000 bodies and I have that trouble with both of them from the beginning, which is very strange as I have never had that trouble with any of my other digital cameras.  It seemed after 100 or so shots, I had lots of stubborn dust bunnies.  At first, I sent them back for cleaning as described in the manual, however now, I use the "wet" method to clean them up, since I would be sending them back every other week for cleaning.  It must have something to do with the sensor heat as you mentioned or something is being leached out of the black material aroung the mirror assembly.  At this point, I think my D7000s are getting much better as they need fewer cleanings.

Thanks,

Ray J

Does this happen in a housing only, topside, or both. If it's condensation in a housing have you tried adding silica gel.
Sounds pretty weird almost like the lens seal is not good or something. From what you say it's not a dirty sensor so cleaning the sensor will not help.
But, cleaning a sensor is easy if you do it with the right tools and follow the correct procdure.

No, I have not used the camera in the housing yet, and you can see the spot on the sensor surface. Cleaning the sensor is the only way to restore the image quality!

Thanks,

Hi Paul: What I mean by "contamination" are visible spot on the sensor, that cannot be removed with in internal sensor cleaner. They appear like they could be the remains of some condensation and, after looking at the progession of "spots on the images", seem to get worse as I used the camera until the images were unusable. I think this problem may be due to the large internal volume of the 28-300, combined with zooming while in live view mode, causing condensation on sensor, resulting in these spots. Last weekend, I was shooting some waterfalls in the Smokies, and I noticed some spot appearing, and actually saw something on the sensor. Later in the day, I could no longer see anything on the sensor, however there are a few very faint artifacts visible if you examine an image of a bright sky under magnification (of the image). This lens seems to be causing the problems, however it is a great lens, I would just like to figure this out. Nikon technical service was no help at all.

Thanks, Ray J

Hi all you D7000 users:

Has anyone heard of any problems with the sensors on the D7000 being more easily contaminated. I have 2 D7000 bodies and both have suffered the same sort of contamination in the last 2 months. I think it may be related to my new 28-300 nikkor, but I want to know what you think. I have never had this problem with my D70, D300, D00s or 7D, it just makes me wonder what's going on.

Thanks,
