Due to the poor performance wide open, this lens would seem to be a one trick pony, the one trick being tilt for deeper focus for landscapes, which is a large part but not all of my interest in trying TS. I am put off a bit by Cicala's observation about the tiny plastic components in the tilt-shift-rotate components, and his crack that there may be a 3D printer fabrication market for these tiny bits in a few years. The Samyang-origin lenses don't have authorized repair in the US, so potentially frail tilt-shift-rotate components make me very nervous about buying this at present, particularly because I have never had a TS lens before. If a year from now there are no reports about the lens breaking, I might reconsider - but I may have saved more for the Canon 24TS by then. And it is possible that Samyang may fine-tune the design.
All that said, I have a lot of fun with the Samyang 14mm f/2.8.
