I have a 5n (new to me), but I have an odd issue: auto-orientation of pictures. At first, no portrait oriented photos were auto-oriented. That is, when imported into Lightroom, they were sideways. I thought "that's odd, not to have orientation in such a camera" but then I remembered sometimes systems use the IS in the lens, and I have a legacy lens. But, on a walk this am, some pictures DID come out oriented correctly. I did a quick google search, and found references to an "orientation sensor" issue on the 5n. Is this something anyone has seen before?
