Wait, this is a full frame, non-fisheye lens that runs at 11mm?! That sounds pretty spectacular all by itself. Has that ever been done before?
That was exactly my question. Any law of physics expert to comment? What is the possibility of successful rectilinearity at that focal length?
That would open up a brand new perspective of lifestyle photography.
The 17 TS-e is already this wide, you just need to shift and stitch to capture it all because a full-frame sensor isn't big enough.
And those of us that do panos have been seeing wider than this basically forever.
While I do stitch my 17 on occasion it does fail (visually) sometimes as the necessity for stitching means that the far edges are at the limits of the image circle and get soft and the perspective looks funky as the view is so extreme.
