i want to, before i die.. much later in life, get one of nikon's 8mm/2.8 fisheyes made for me. see's behind the camera on a fullframe sensor or 135 format. similar effect to this lens.
i think they're about 70 grand by special request. my friends will buy 2-seater cars and date girls half their age, and i'll buy a seventy thousand dollar lens.
I don't know, but it looks a bit... tacky. The photos are really distorted at the edges too. I'd probably go with a Sigma 8mm fisheye lens, rather than go the extra -2.4mm.
