Yes I had a UV filter, no hood. I was asking for it of course shooting straight into the sun, but the flare on this lens can be pretty offensive at times. If you look at the full pano and zoom in you can see where it is the worst, the reflection compounds kind of erratically resulting in that massive red circle. I toned the red channel down a lot because it just overwhelmed the shot.
I don't really know what I'm doing photography wise so I'm sure there's a way to avoid it (read do not shoot directly into the sun), but my location wasn't really conducive to that the way I wanted to frame the shot.
