I'm reading about the ultra wide angle lenses that go to 114 degrees (mostly for architectural and landscape). How small will those lenses go (using degrees, again)?

I'm not sure I understand your question.
The 114 degrees refers to the angle of view. The shorter the focal length the wider the angle of view. The angle of view of the Canon 14mm f2.8L lens is 114 degrees on a full frame camera. The angle of view doesn't vary with a fixed-focal-length lens. The angle of view will be less on a camera with a sensor smaller than full-frame. A 1.6 crop-factor camera with that 14mm lens mounted would have an angle of view of 114/1.6=71.25 degrees(I think). Lens manufacturers put the angle of view of their lenses in the specifications. If you want to know what the angle of view of a zoom lens is at the long end of the zoom range, check the specifications.
Did that help?

You mean narrow? My Tokina 11-16mm f2.8 goes from 104d to 82d. I love this lens. It has the lowest distortion of any of the ultrawides. I also love the f2.8 speed. The build quality is as good as anybody's, includind Nikon's. I shoot a fair amount of architecture and am very happy with this lens.
