Check out the link that RTPVid posted (which, BTW, thanks for that link!!)! I wouldn't have thought so either, but the dust speck I saw inside my lens was long and narrow and matched what I was seeing in my photos.
At this point, I'm just glad it wasn't my sensor. I clean my own sensors and though I've done it a few times it still makes me a little nervous. I just cleaned it the other day, and then this happens...talk about a sinking feeling. The 85 had the spots, but in a totally different pattern and not near as obvious so that pretty much narrowed it down to a lens issue. I just hope it isn't an arm and a leg to get it serviced.
