      and I'm confused about the 1:1 chip spec.... when I look at the specs
      on cameras, I don't seem to find any info about whether or not it uses
      the full chip... how would I spec that????

      Hi Hue... I'm in Africa (Kenya, Tanzinia and Eqypt) right now using two Kodak
      14n cameras... the only issue with these digital bodies is in low light
      conditions and the noise level can be high... this has been improved with the
      newer Kodak SLRn version bodies and the 14n version is still quite usuable (I
      have one of each) for everthing other than low light imaging. The bodies come
      in both a Canon and Nikon mount, but you will need to get them through eBay
      since Kodak is no longer making them... a good condition SLRn will probably
      cost around $2700+, the older 14n, $1800+. I am using a Nikkor 6mm fisheye,
      the best lens I've seen... again eBay, probably about $2300+ since they are in
      demand now. The Kodaks are great if you tie them to a laptop with the FireWire
      port... then you can shoot with direct control from the laptop and see large
      previews as you shoot... also the files are saved directly to the laptop, so
      you have almost
      unlimited disk space as compared to CF cards, etc... great for long time-lapse
      work.

      PS: Can you forward this to the fulldome group... I can't do it since I am using
      a special international setup to check email and it will not be accepted by
      yahoo, just bounces back... take care!

        Here are a few screen shots from B&H. I find them to
        be the best place on the web to do comparative
        equipment research, though I tend to shop locally once
        I figure out which model is best. Camera's that have
        the full sensor or 1:1 (equivelant size to 35mm film)
        will state this multiple times in both the features
        and specifications. This is a major selling point for
        them.

        Camera's that do not will state this information as
        the "focal length multiplier." This is the
        magnification that occurs whenever the sensor is not
        35mm. Say you have a 20mm lens and you put it on the
        Canon 20D, you'll end up with the equivelant of a 32mm
        lens. Nikon has developed "DX" lenses that corrects
        this magnification issue. The only problem is they
        don't make a circular fisheye in this type of lens.
        To push this line they haven't developed a full frame
        sensor.

          Actually "DX" (Sigma calls them "DC" Tamron Di) lenses don't correct
          the magnification factor and the the DX lenses do not give full
          coverage on a full frame camera.

          These "digital" lenses (all manufacturers make them, only fully cover
          the smaller APC sensor) so the lenses can be a bit smaller and
          lighter and maybe with faster optics...)

          To Quote DPreview,

          "The AF-S DX VR 18-200mm F3.5-5.6G IF-ED Zoom-Nikkor (try saying that
          three times quickly) provides an equivelant field of view range of 27
          to 300 mm on a DX format digital SLR (such as the newly announced
          D200). "

          So, the digital camera you want is the new Canon 5 D with full 35 mm
          frame at around $3000 grand and a nice 8 mm circular fish eye (sigma
          just announces a new one...)
