i was reading a link from nikon rumors the other night ,it took me to a website by a wildlife photographer ,on his site he had a hints and tips page one of the tips was to look just inside your camera throat i.e in front of the mirror for brass swarf .caused by metal to metal contact upon changing lenses this has the potential to end up on your sensor
i checked this on both my cameras and as soon as i looked i could see the gleam of brass filings lying there ,so that part was true .its something i have overlooked in the past as i always try to change lenses quickly to avoid dust exposure .
the cure is simple you will need a couple of Q tips or johnsons ear buds ,some lens cleaning fluid .thats it apply a small drop of cleaning fluid to the ear bud and gently wipe out the plastic in the bottom of the camera lens throat .avoid touching the felt that the mirror rests on if theres any swarf on that use a wooden tooth pick to remove it .
thats it you will find this also removes some "grease" that myself and eric were jesting about last week .a simple 5 minute job but one that could save you a lot of future aggro especially if you change lenses a lot ,as the swarf is a by product of this
Thanks Jeff...something else to go and check.
I read, back in early digital days (before inbuilt sensor cleaners), that one way to remove sensor dust was to stick some double sided tape to the inside of a body cap and fix it on the body. Then place the camera face down on the floor of your car and take a drive. Apparently the vibration from the car would cause dust to be shaken down and stick to the tape.
Never tried it myself but I wonder if it would do the same for the swarf?
