The Olympus lens manual says it has essentially the same coverage as a 21mm
lens.

No, it would be terrible. This lens is for one specific purpose only, and
furthermore, you have to be a licensed architect to legally use it. Other
things it is useless for: trees, waterfalls, tiny, long things (with
extension tubes). In short, it will be totally useless for any long object
EXCEPT a boring building.
So Warren, if you come upon one of these, I'd suggest you notify me
immediately, so I can see it gets in the proper hands! In return, I will
send you a Zuiko 24/2.8 that is a faster lens and more suitable for use by
non-architects.
(Grumble, grumble, grumble -- now there's THREE of us on the list openly
hunting for one of these... :-)
(Seriously: I think it would be terrible for slot canyons, with you having
to worry about getting sand or water in it, or banging it on a rock or
something. :-)
(Really seriously: if you're unsure about plunking down a grand or so for
the 24, perhaps you can pick up a 35mm shift for less than half that amount
to see if it makes your socks go up and down. Then you can sell and trade
up if you like it.)
