can anyone tel me what are these? dust on sensor? last time i faced the prob too but just one short stroke, then, i spent $27 to clean the sensor at nsc, but after 2 weeks the dot appeared again, and now it has so many...
is this must clean at nsc or i can clean them myself? coz $27 is not cheap... :'(
