Everytime when i look into my D40 view finder, i could see 2 spots and a bristle. However, my pictures does not turn out that there are dust. I try to use a blower on my D40 sensor but it does not work. I tried to clean my lens, it does not work either.
Shld i send to NSC to clean?
Am thinking of upgrading from D40 to D80. What are some consideration?
