This was a first and difficult time for me. I have read all the things about cleaning the sensor so I gave it a try. I have pic pads and Eclips. I first tried water and picpad and it would not clean it proper. Then I use Exlips. This did fair but had one spot that would not clean off. Then I used Goo Gone and it took of the spot but left a smeat. Then I recleaned with Eclips and pic pad and now it's clean as a whistle... I calle Souther Photo and they were going to charge me 50 bucks to clean it and I didn't feel like going deer hunting. I'm proud that I was able to do this myself and no that now I can keep my sensor clean.. Still waiting for the D200 to come back in stock. I hope to have one by May. RM look out.
