Remember my ponderings about a image-compressing-converter for digicams, to achieve full-angle coverage on a chip smaller than 24x36mm? IOW, a inverse teleconverter?
This is what Dan Slater wrote about this subject, in the context of adapting a 6mm/f5.6 Nikon fisheye to a Nikon D1: http://www.nearfield.com/~dan/Photo/wide/fish/index.htm (interesting side-note: the other/main reason for him ot use an image-compressor is that the D1 doesn't have mirror lockup, which is needed with the protruding rear element of these fisheyes (applies to one or more other old Nikon fisheyes as well)....and this image-compressor also acts as a relay-lens, moving the lens further from the film plane) PS: if anyone knows where to find a Nikon 6mm/f5.6 for sale, give me a holler!....I have known Dan's work for half a decade by now, and one of his most staggering concepts is a rotating-film camera with this 6mm (only works with digital)....resulting in an angular coverage of 220x360 degrees....mind-boggling. (if you want more brain-cracking ponderings about this concept, try one of Andy Davidhazy's articles, where he argues that on the top and bottom of the image, where horizons not only match/meet, but overlap, you can in fact see beyond infinity....link is on my homepage: http://www.a1.nl/phomepag/markerink/mainpage.htm (do a browser text search on Andy/Andrew)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand <[EMAIL PROTECTED]> [note: 'a-one' & 'en-el'!] * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
