Had my new T2i about a month now and have finally started to figure it out. Got through the manual just this past weekend. On a bit of a sour note I think I picked up a couple of specs on my sensor. This is my first DSLR so I'm a bit concerned about removing them. It's been suggested to simply try using a blower on it, very gently. Any cleaning suggestions are very welcome. 1. 2. 3. 4. 5.
