How practical is circular? Anyone could sell these shots?
I think the 180º circular fisheye was developed for full-sky shots, cloud studies, etc., but was quickly adopted for other "artistic" uses. I have no idea how many circular photos are actually sold, but I remember occasionally seeing them in magazines like National Geographic beginning almost fifty years ago. I've seen one or two prints in galleries...it's certainly not a look with wide appeal (uh, pardon the pun), and not easy to keep interesting, but that's how it is with specialty optics. Oh, and not easy to mount and frame a print effectively.
