heck cant vote, i would go for 17mm too (if lower even better!)
had the gd fortune of checking out output from 3 different FishEyes..adn several other such shots from unknown pcs.
at first the shot orientation and extreme barrel distortion attracts me to view the image, but after coming back for a 2nd glimpse, it lost much of its strong appeal on me for some reasons. too much curves??
of cos i have seen some memorable FE shots, but i kinda think these are the odd few rather than the norm.
i figure if i do indeed get to own a FE, it could be an infrequently used lens, but one that is most interesting to use whenever i really feel like it. hopefully then i would have mastered the 'right' techniques and perspective to appreciate it fully.
just my two pennies..
anyone like to share their FE masterpcs here
