I started typing this up last night, got distracted, noticed there is a related thread today, but decided a separate thread was still worthwhile:
I have noted that a "Fisheye" lens will have a wider FOV than an UWA lens of the same focal length - yeah, not exactly news to most, just the opening point of my discussion/query. As I understand it this stems from the rectilinear view from the UWA vs the very distorted circular polar/radial view of the FE - the UWA "consumes" FOV to maintain perspective.
I have a Rokinon 8mm FE. It is "fun" and can take some interesting shots, including shots where the fisheye distortion is not really noticeable due to the subject matter (beach shots with horizon across the middle of the view, for example). There are times when I would like to "zoom" the 8mm and get to about 15mm or even higher, so I usually just swap out for my 15-85. So I have been reviewing the specs and sample photos of the common FE/UWA lenses, including the Canon 10-22 and Tokina 10-17 mentioned in the thread title, trying to figure out whether either of those archetypes will scratch my itch for zooming from FE/UWA to plain-old WA.
For those folks that have used both UWAs and FEs at comparable focal length ranges: do you feel the FE look gets tired pretty quickly, and that having a single prime FE (like my affordable Rokinon 8mm) is enough to satisfy the FE needs and that the rectilinear UWAs are more useful/pleasing to capture those, well, ultra-wide shots?
The Tokina is the only affordable zoom that provides true 180 deg FOV (or close to it) on a crop like my T3i. The new Canon 8-15mm FE is undoubtedly a fine lens, but not sure it would be worth the money for the novelty of it all, and AFAIK from 8-10mm simply provides dark corners on crop bodies without going whole hog to a fully-circular image.
The Canon 10-22 seems to be well-regarded in the UWA arena, with healthy competition from the Tokina 11-16 (constant 2.8) and Sigma 10-20s (either constant 3.5 or very affordable price on the variable aperture).
Your thoughts on which type of lens (FE vs UWA) has proved more useful (and used more) in your own experiences are appreciated.
