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!
