If it is a light leak...

No issues in portrait mode...

I saw that you had said that; a bad gel filter is still a possibility by either shifting or getting internal reflections within the filter assembly.

I see folks suggesting a light leak, and that's possible too. If it's a light leak in your lens adapter, the reason it would be showing only with the ND filter is simply that without the ND filter, the leak isn't bright enough to show over the image -- but it would really always be there. Test for this by trying a shot with a lens cap on. If it's a light leak, you'll get an image of the leak by itself with an opaque lens cap on....

Of course, the reason you might not see a light leak with the camera rotated would be that the leak is blocked by you hand, a shift in the play in the adapter, etc.
