fainted marks spotted @ F14 (seldom shoot till F14 but..)
F18
F22
F29
looks like scratch to me.. when I locked the mirror, I saw like hairline dust, used blower but seems like 2 perm marks, un removable.
is it a layer of thin membrane o film over the sensor?
worried that it might b scratch marks..
cleaning at NSC @ 26.75 for D90..
