This evening I performed my first wet sensor clean using the copperhill wet/dry kit I have just recieved. I performed a few dry runs with the brush first and the did about half a dozen wet runs before I was happy with the result. However I have noticed some very slight marks that dont seem to want to move(i doubt they will show in any real pics).
I seem to remember seeing these marks last time I did a dry clean last year. My question is this, Is this camera lube, or have I scratched my low pass filter with my earlier dry clean? My previous efort at dry cleaning was using the best quality nylon artists brush I could find on the advice of a relative who was the editor of a british photo magazine(so I trust him, or at least did lol).
I notice that they seem to be fainter in the after shot so Im hoping that it is some stuborn lubricant that has probably been there since I recieved the camera. Does anybody have any ideas?
I just realized the shots are in the wrong order!!
