FS: EOS Sigma 8mm/f4.0 circular fisheye, or Contax/Yashica mount

[Willem-Jan Markerink <w.j.markerink@xxxxx>]

For Sale:

- Brand new Sigma 8mm/f4.0, originally Contax/Yashica, to be modified to 
Canon EOS mount
- Includes box, manual, blank warranty cards and 3 filters (internal screw 
system)

- US$650, or make offer (US$500 in its original Contax/Yashica mount)
(will consider trade with a A2-format flatbed scanner (low res like 300dpi 
is okay))

This is a special modification, since until recently, Sigma didn't make 
this lens in EOS-mount at all (and others only on special request/order). 
So this modified version does not have AF nor aperture coupling, 
only manual focus and work-aperture, but a fine piece of optics 
nontheless, on par with OEM optics of other brands....Nikon/fisheye expert 
David Ruether (aka Bob Neumann on Usenet) rates it on par with the Nikon 
8mm/f2.8, which is not only more expensive, but also more bulky and more 
heavy.
Note that this all-manual version also avoids the upwards-compatibility 
problems common with older Sigma/Tokina/Tamron/etc lenses when being 
mounted on a newer/later EOS body....new isn't always better....this 
version will work on any possible EOS-body in the future.

For technical details on this Sigma and other fisheyes (both full 
frame and circular, both 35mm and medium format), including some 
pictorial samples, in a sublimation of fisheye, infrared and winter, check
