Do Not attempt to clean your viewfinder

I can clean the sensor all day long. I can remove the focusing screen easily and clean it. But, do not ever touch the bottom of of the condenser lens which sits on top of the focusing matte screen. The more you clean, dirtier it gets. And when you blow air in it, you'll get more and more dust on top of the lens where you can't get to it.

If you get some dust in there, just leave it alone. Hard lesson learned. Ended up selling my 5Dc for $950 instead of $1050 I wanted to.

what? im confused

Don't worry bout it. Just don't try to clean the viewfinder dust.

I don't know what I'm going to do when my sensor gets dirty....I don't even like changing lenses...

I am with you, that image is not the tear down of our DSLRs, so I don't know what that is supposed to be.

I have taken the AF screen off and cleaned up in that area on a few cameras in the past. The largest issue I ever had was getting all the dust off the AF screen putting it back. I used all very small utensils with microfiber material.

I guess if you want to get even further up into that area, you have to have a clean room and probably a good micro-vacuum system. Here is a past thread on the same subject.

Here is what this person says to do in order to eliminate the dust in the viewfinder.

Sensor cleaning is easy......simple and effective.

Thanks for the links. I would've certainly tried it yesterday if I saw it.

That begs the question...
Why bother getting a DSLR with interchangeable lenses?
Why not stick to a P&S?
What am I missing?

The very first time I changed the lens I managed to get some dirt in there, luckily it never shows up on the images, being the fool that I was I tried to clean the focusing screen, and ended up with small minute scratches on there instead. After changing the focusing screen I have learned that as long as it doesn't show up on the pictures then the little fibers/hairs/dirt come with all DSLR cameras! So I guess unless it gets really bad then just live with it.

Yeah, but if your 7D is anything like mine it just doesn't seem to need cleaning. Dunno what Canon have done to it, but I'm highly impressed.

Same here... I used to have to swab my old 10D sensor every four months on average, but after almost a year, I haven't had to do anything to my 7D sensor.

That's the diagram of Canon Viewfinder from Eye Piece to Focusing Screen.
