Strange one,

I've got what looks like a dust spot on the sensor. It's not on the lens ive thoroughly cleaned it and tried it with another lens and i get the same spot in same position.I did a dust check "picture" but it shows completley clean!? Then sensor shake cleaning several times but its still the same.

Now what? mirror up cleaning with lenspen? Some advice would be appreciated many thanks

Dan.

Can you clarify. Is this spot visible on actual photographs or only when you look through the viewfinder.

If it's on the sensor you won't see it through the viewfinder - if you can see it through the viewfinder it will be on the mirror or the focussing screen.

Whatever you do do not use a lens pen on your sensor .

Invest in an Arctic Butterfly or swabs for sensor cleaning.

I am a butterfly enthusiast as well, but only for dry dust. It will simply smear grease.

How do you get grease on the sensor?

Blimey, they must serve you the oil they were fried in as well then

I accidentally got some saliva on my sensor because I was talking to someone while cleaning it. I shall not make that mistake again, damn 's' sound!

I confess I send mine off to be cleaned works out the same as buying the swabs and Im not confident enough to attempt it.

Dont use the lenspen on the sensor though!!!! lens (its in the name )
All the best

Well to clarify its definately on the sensor (I dont understand though how it DOESENT show up in the dust alert picture). It shows up in my pics. And there is also stubborn dust on the mirror! I'm going to try a hairdryer on cold to see if i can blow it out.....wish me luck


thanks for everyone's advice

Will await the outcome
All the best
