You're missing UWA
Rokinon 14mm in Canon mount
I'm sure there are other alternatives as well.
I'm probably getting an UWA myself once my B&H refund of the 135L goes through (decided to keep my 70-200 over it). For me at least, UWA is some of the most fun to shoot, especially with a close-focusing lens and lots of UWA focus pretty closely.
