I too own Canon's the sensor cleaning system thay use is very good I've had no problems for the last 6 years on my 7D,5Dll.

I generally find the need to clean sensors on these Nikons after several thousand shutter actuations. Their built in sensor cleaner is a bad joke. Canon, on the other hand, must have an effective cleaner and/or a method of manufacturing that reduces oil spatter. I've never had to clean my Canons, even a T2i that is several years old. Go figure. But I love the image on that D7200. Bought mine refurbished.
