I have owned a Nikon D300 and D700 and ALWAYS wet cleaned my sensor with eclipse and used the Copperhill method. No issues whatsoever... EVER! But as of tonight I am left with a crappy looking sensor and will be picking up a new NEX-6 tomorrow and selling this one on ebay for whatever I can get for it. ( see pic ) I emailed CopperHill and they said it had to be a defective coating on the sensor. I have my doubts. I am beside myself right now. But now my question is.. at some point.. it will need to be wet cleaned. They all do.. What do I clean it with if Eclipse is not the answer?
