Weird Canon 7D artifact?
So all of a sudden today I see this dark line on the left of my photos, like a hair or pine needle or something- you can see it here over the lampshade.
I of course assumed it was something on the lens so I wiped it off, did sensor cleaning, etc. But the really weird thing is, it only shows up on videos and on stills done in "video mode," ie using the LCD screen!!
If I take a still picture in the normal way, through the viewfinder, everything is fine! To be clear: all other circumstances being exactly the same, taking a picture with the LCD yields this artifact, while taking the picture looking through the viewfinder does not.
How is this possible and what could be the cause?? Thanks!

Response by poster: Hmmm sounds plausible. It is under warranty so I suppose I end up sending it back to Canon.

Response by poster: Update: I put it in manual cleaning mode, it was just a little white hair or something on the mirror; I got it out and everything is fine now! Thanks zsazsa!

BTW, two things you can try to replicate this in normal look-through-the-viewfinder picture taking mode would be: taking a shot with mirror lockup on (to see if it's just the mirror's fault), and taking a long (several seconds) exposure (to see if it's the open shutter's fault). In any case, it looks too sharp to be anything but something that's within millimeters of the front of the sensor.
