#11. "RE: D7000 sensor artifact/problem - help needed" In response to In response to 9
I believe I’ve had a similar experience to you. I acquired my D7000 back in November and noticed that at about 2600 clicks the sensor was really grungy. I tried a Rocket Blower to no avail. In fact it seemed to add more spots then it removed with some spots not budging at all. And the self-cleaning cycle had absolutely no effect.
I never did a wet cleaning but figured now’s a good time to try. And as previously mentioned, the cost of the supplies was about what it would cost to have the local brick and mortar do it. I bought Photographic Solutions Sensor Swab’s (12 in a pack) and Eclipse solution (2 fl oz). I consider myself a bit above average with mechanical ability, but find myself now age appropriately shaky. It took me two wipes to get the sensor relatively clean. But I believe it may have taken me two tries in that never having done it before I used a really light pressure the first time. After watching the video on Photographic Solutions web site again, I used a bit more pressure on the second swipe and only had three minor spots toward the edges that I felt I could live with till the next cleaning. If two swipes to clean the sensor holds I have enough supplies to do 6 cleanings for the price of having it done for me once.
This is a before cleaning test shot.
And this was after.
To sum up, it seems scary to do this if you never have done one, but after my first attempt I have more confidence and would not hesitate to do it again. If you have average mechanical ability, you should have no problem doing it yourself. Just go to Photographic Solutions site and watch their video a few times to build up your confidence. Just keep in mind that as you look into the mirror box the top right of the image will be on the bottom right of the sensor.
