Where is the dust?

[TTiiiiiiiiiiiAN]

Hi guys

I've got a question here about my dslr. i don't know if this is the right place to post.

anyway, I've got an annoying dust somewhere in my camera. I can see it through the viewfinder. It's not on the lenses cos it appears on the same spot whatever lens is mounted. i've also checked the sensor, it's perfectly clean. even if it was on the sensor, I would see it from the photos I've taken. but no, it's not there. also when using liveview mode, the flaw disappears too.

Any ideas?

Thanks

As you say, you have dust in the viewfinder.

No big deal, since it doesn't show in the pics. Mine gets dusty, too - I take a small watercolor brush and clean the eyepiece every now and then. If the dust is inside, I wouldn't try to open anything myself - then Canon can clean it, but for a fee.

As Janke says, it's probably on the ground glass (plastic?) of the viewfinder. A camera repair store could probably open up the viewfinder and clean it for you. If it's still under warrantee, call Canon and see if it would be covered. Dust should not be able to get into the viewfinder. It was probably already in there when manufactured and movement knocked it lose onto the ground glass.

I'm sure it's inside. and it's a new camera.

Of course, as Khaver says, it can also be on the surface of the ground glass. In that case, you can access it by removing the lens, but don't touch it, not even with a brush. Only use a clean rubber bulb to puff some air on it. Do not use "canned air", that may leave bad stains.

This reminds me of something I did to my HV30. In attempting to clear away a particle in the viewfinder, I pushed in the ground glass, resulting in an unusable viewfinder. It's probably an easy fix, but since the camera was going into service for a major repair, I left it as is. I'll be extra careful cleaning the viewfinder when the HV30 is returned.

[Janke]

There's no ground glass in the HV30 finder - what are you referring to? The eyepiece?

[vadis]

Yes, the eyepiece.

It could be on the mirror, which lifts out of the way when the picture is taken - which is why you don't see the dust in the pictures.

Go very careful with cleaning your camera. I wouldn't clean anything more than the lenses myself - get canon to clean it for you - it's the safest way.

If you can see the dust in the lcd viewfinder, and on hd footage, but not photographs, then that probably means the built in 'dust reduction' filter is automatically removing it from still images.
I had a similar problem with my 550 which turned out to be a tiny hair on the sensor, almost impossible to spot with the naked eye. The sensor cleaning didn't shift it so
I gently blew on the sensor and that fixed it.

Just make sure you don't have bread crumbs in your mouth before blowing...

Yes, if you're a drooler then this method is not for you!
