Don't use any old cloth! You could damage your sensor!
Go to SRS and get some of these link ASAP.

These are for use on your sensor only, you may also have dust in the viewfinder like me but as long as they don't affect your photos then don't worry about them. They will just be an annoyance.

It depends on where the dust is. I guess it is on the mirror or sensor. If this is the case I would keep a wet clean as mentioned by Steve as the last option. The first option would be the inbuilt sensor shaker. Next I would try an Arctic Butterfly.

I was a little wary of touching the sensor..So have yet to go down that road, I can see the dirt in the viewfinder and marks are transfered to my images..

The dust in your viewfinder is not transfered onto your images...it is the dirt on the sensor that does that!....you need a sensor clean!

If you can see it in the viewfinder and in your pictures then it must be on the lens.

That depends on whether the marks in the viewfinder match those on the image. It could be a dirty viewfinder and a dirty sensor/lens.

I absolutely refuse to believe that, it is impossible for marks in the viewfinder to be on the final image, why dont you post one of the affected pictures?

In your first post you dont say where the dust and hairs actually are, are they on the mirror or the focussing screen when looking into the camera body or are they on the screen when looking through the viewfinder?

In any event, neither mirror nor focusing screen should be wiped with anything, They are very fragile and easily damaged.

The sensor can be cleaned with the appropriate products, but should not be necessary very often. In fact, I have never cleaned a sensor and have only ever used a rocket blower if the built in dust removal system wasn't enough.

If it appears on your picture, then the dirt is on your sensor.

It could be in the lens if you're using very high f-numbers (f22 ish) but those would still look more translucent more like blobs then a real spot if they are big enough to see...

I really doubt that anything in the lens would show up Stefan. Quite large defects go unseen and they certainly wouldn't appear as a definite blob or mark.

I have noticed something strange. I used to get quite a bit of muck on my K20D sensor. Stuff that was greasy end needed a wet wipe. I have yet to clean any of my K-5s sensors Even the one I had replaced that ad about 20,000 on the clock.

I haven't changed my in the field lens changing Habits.
