Heyyy, sedan gang! You've given me courage to hold off on the truck/van purchase for now 😆 Thanks for sharing! Have you ever tried the Canon 10-18mm? Should give you the same FOV as the fisheye with some added benefits (zoom + IS). I'm looking at this as a lightweight alternative to my Tokina 11-16mm. You might need to modify the mount on the EF-S though.
