I have searched the forums and havent found what im looking for, i have a few specs of dust that i notice when im looking thru the veiw finder i have cleaned the lens and the filter, and have blown out the inside of my camera with a battery opperated blower, Spots are still there, and i dont have a sensor brush to clean, is there anything els to clean the thing that is sitting at an angle when i take off my lens, is taht the sensor or the mirror.

That is the mirror...the sensor is under the mirror...You must lock up the mirror to see the sensor.

Don't touch the sensor until you know what you're doing!

Dust on the mirror does not affect the image.

It's on the mirror.

so just because im seeing it in the view finder doesnt mean it will be on the image?

and if it does end up on the image should i take it in to get the sensor cleaned at a canon shop?

You will NOT see sensor dust when you look in the mirror, you can only see sensor dust on the image especially when you shoot at small apertures like f/8 or smaller. Sensor dust is a fact of life when shooting with DSLR's, I use the Sensor Brush System myself, and never think twice about being extra careful hen changing lenses. It's so easy cleaning the sensor with that system...a 5 min job...

It could also be dust inside the viewfinder.

Dust on the mirror or in the viewvinder will not affect image output.

Take a test shot of a clear blue sky at f22, (and focussed at infinity), and then do an auto-levels in PS to see if the dust is on the sensor and affecting your images.

Thankyou guys for your help, I was shooting yesterday for the shutter speed challenge and came home and all of my images had something on them and they were un usable since i cant edit them out in basic editing rules, so i cleaned my lens and blew out everything and im going back right know to re compose my shots from last night,
hopefull i got whatever it was.

Thanks again

Seems like the marks you speak of is either on your lens or on the sensor. Hopefully only on the lens.

If it is actually sensor dust that's an issue, you don't need to go all-out with copperhill right away - just select "sensor cleaning" in your menu, it'll open the shutter and lock up the mirror - give it a good wafting with the blower, that'll usually get most of the dust off.

I did that a couple of times, last night i re composed my shutter speed shots and came with the same results, im going to call the canon place today and ask how much to clean my sensor.

even though i did see a tutorial online on how to use a sensor brush, but im not sure if i want to do that.

I'd strongly advise you to use the copperhill method, you can get their packs pretty cheap on ebay, and you won't have to wait for the canon people to mess around with it. That's all they'll use anyway, you know - i'd personally rather do it myself than leave it to some half-trained service centre monkey :)

what is the copperhill method.

at calumet they sell a sensor brush and the tutorial was lock the mirror, blow out the brush, use one swipe left to right, blow of the brush, and repeat 2 or 3 times.

is that all you do or is there more to it.

The copperhill method is similar... the method you describe however only uses static attraction to pick up the dust particles, which is no use for things that may have stuck to your sensor. The copperhill method involves using a PecPad on a spatula, soaked in Eclipse fluid, which will dissolve most bits of gunk that end up on the sensor as well as picking up loose dust. You swipe it across the sensor in the same way - do a forum search for past threads about the copperhill method, you'll find lots of information.

sounds scarry, but i will look for that kit today, ill look online and calumet probably has it but probably really expensive.

Thankyou for your help,

Nah, they ship worldwide, for only a bit extra - i always buy my cleaning stuff from them, highly recommend it.

well i called canon yesterday to see what the charge would be to get my sensor cleaned, he told me that it was no charge since i have had my camera less then a year the cleaning is under warranty, has anyone ever heard that before,
whats great is the canon center is right around the corner from my house so i could just walk it in,
