I just rented it for my recent solo trip.. it was a lot of fun! More than I expected. Though I can't justify owning it in the real world - especially at $650 new (couldn't find a used A-mount copy) which would make it my most expensive lens. This is why I rented, but I almost regret not just buying it so I have it for future Disney trips.. fisheye works so well there (and to think how long I resisted the fish

). I'm tempted now to get one of those Vivitar/Samyang/Rokinon/whatever 8mm f/3.5 MF-only fisheyes.
