Never took the lens off until today, there is a ton of dust that i can see when looking through the camera eye. but cannot see any on the mirror. How can all this be cleaned? I didn't want to do anything until i asked the pro's but I am upset that there is all of this dust in there. I MEAN ALOT!

Not that i can tell, but it is hard to keep my eye on the photo with all the black specs.

Go outside, put your camera on f22, take a picture of the sky. Go back in, open it in Photoshop, and run an auto-levels on it. If you have dust on your sensor, it'll be obvious.

Sounds like dust on the bottom of the view finder. Take the lens off, look up at where the mirror bounces the light. That area is probably dirty. Gently clean it with a bulb blower or whatever you have. DSLR's will require periodic cleaning, for both the optics and the sensor.

You have cleaned the eyepiece, right?

Shay's right!! - you do not see dust on the sensor by looking through the viewfinder - Dust on the sensor only shows up later in your images.
Dust that you see looking through the viewfinder is due to grunge/dust motes on the bottom of the pentaprism or the viewfinder screen situated directly superior to the mirror while the shutter is closed. It really doesn't hurt anything if you just ignore it.
Theoretically if it gets real dusty, dust might migrate from the pentaprism to the sensor where you won't see it in the viewfinder any more, just in your images later. So it is worthwhile to blow it out occaisionally, but don't fret over it too much.
You can carefully blow out the box and the area above the mirror with a rocket blower. You can order one here http://www.naturephotographers.net/gs/hamabulb.html

Yes the eye is the first thing i cleaned, when i took the lens off and i gently blew in there some of it moved but just moved around. Seems like static keeps it from moving.

The Sensor Brush from www.visibledust.com might help with removing the dust is static electricity is a problem.

if you have dust on your viewfinder - for the love of god don't go blowing it around! It'll end up on your mirror and eventually sensor! If it ain't showing up on your photos, leave well enough alone.
Unless of course you have a good brush or whatever. Blowing is never a good solution inside your camera.

Doc - from page 40 of the Canon manual for the 350XT ( can be downloaded from the Canonusa.com website ) - Cleaning the sensor ( or the viewfinder screen - my edit ) can be accomplished with a bulb blower -do not insert the tip past the lens mount. Do not use a brush. Do not use canned air.
EG; like I said, and Shay said, CAREFULLY use a rocket bulb blower as per Canon's manual. I did say carefully in my first post too. I do this to my DSLRS as needed - not frequently, but as needed. I prefer to ignore dust on the viewfinder until is really bugs me - then I blow it out gently without the shutter being open.

Do not use canned air.This is what I was shooting for. For people that aren't comfortable with the innards of their camera, its best to tell them to go easy. That's what I was going for. You can make matters a lot worse by trying to get rid of a little bit of dust on the inside of your viewfinder.
You know what I'm saying, you just admitted it yourself! :lol3
coolcaris300soon: PF is right. Ignore me, I'm having a cynical bastard day :wave
(but please don't point your air compressor in your open dslr body!)

Yes, no canned air, but a bulb blower works great. I use it when I need to clean. I have the copperhill cleaning kit, but still have not had to use it yet. The bulb blower gets it done for me right now.
Just never use canned air. Why? because they say so! That's good enough fo me hehehe :wink

We're cool Doc. I agree - no air compressors or canned sources of air!!
I use an air compressor to clean the grass off of my 25HP lawn mower, NOT my cameras :rofl :rofl
You don't want to be blowing stuff under the anti-aliasing filter in front of the sensor - then you are in a mess, because it is going back to Canon, and they will spank your hand or other parts, including your billfold.

one spec is in the pictures. I can see it in the view on the bottom left corner but it shows up in pics around the middle. IT is the same spec.
ughhhhhhhh looks like a hard water spot but small.
