My view-finder looks kinda smudgy and there are some tiny dust specks, that are quite distracting during shoot. I tried cleaning the front and back part of the viewfinder prism, and mirror using an ear-bud and a lens pen. That didn't work but made it worse .
I sent it for Nikon-servicing from a dealer in my place, clearly explaining what to do, but returned in the same condition.
What to do nw? Should I go to Chennai and give them by hand?
