I take it you were cleaning the mirror when you put your finger through it?
No Brian, I was changing the lens. I was holding the camera in my left hand with my index finger on the lens release button. The lens was in my right hand. The camera slipped and as I grabbed it, my finger slipped in and just touched the mirror......Kapoof!!!! It still worked, but without Auto Focus and with artifacts. With the mirror removed the artifacts went away. I visited my local dealer for a new mirror. The salesman claimed they did not supply parts, only repairs. (They obviously want the big money.) I bought a new mirror from eBait for $70. Three days later the Dealers boss called and said he would send me one for $40......Too Late!!!!! Below are pictures of the said mirror. Easy to change.
I clean my sensors myself, too expensive to get the dealer to do it. Never touch the sensor with your fingers. I use a Canadian made Arctic Butterfly brush which has a motor that rotates the brush, creating a static charge in the brush and that lifts the loose dust off the sensor. However it's very Hard to remove stuff like baked on pollen and it has to be removed by physically rubbing it off. The danger is that if you press too hard the sensor could be knocked off alignment or scratched. I use a Sensor Klear (made by Lenspen) which can gently scrape of the pollen. That is by far the most scary part.

Lens facing side of the mirror. Note the scratches on the top left corner. They have been there since shortly after I bought the camera and have had no effect on the pictures.
