    A few shots with my new D700:

    I don't think any other lens goes as wide in a rectilinear projection as
    the Sigma 12-24 full frame for an SLR and it's pretty good. The corners
    do get soft at the very end, not obvious on this one, original file:

    Barrel/pincushion is almost perfect though it's hard to frame straight
    hand held, some of those are cropped or perspective corrected in
    photoshop but it is possible to use this setup to make nice photos; not
    necessarily always a total freak show.

    Now to saw the hood off the 10.5mm DX fisheye for a greater than 180
    degree view (almost) circular fisheye (cropped on the top & bottom).

    I'm going to be bummed shooting telephoto though on un-cropped full
    frame so the D200 will remain for that.



    I sawed off the hood off my 10.5mm DX fisheye for a greater than 180
    degree view (almost) circular fisheye (cropped on the top & bottom). It
    was pretty easy. Here's a test shot at various apertures:

    There is some CA in the crops which I adjusted out in adobe raw
    converter. There's also some purple ghosting when stopped down past f/8
    but still amazing flare resistance, considering. This shot doesn't
    really test edge sharpness (focus at infinity with foreground in the edges).

    Here's a DX crop to compare:

    The method for removing the shade is from a youtube tutorial but I
    didn't bother with tape, only the aluminum can metal trimmed with
    scissors and slipped firmly into the slot inside the hood to protect
    things when cutting off with a hacksaw. Cut off enough that it comes out
    in one piece then I used wire cutters to shorten the large parts of the
    shade & put that in the lens cap for a spacer.

    Thanks, it should be fun.

    The 10.5 is my only DX lens and is pretty interesting on FX though it'll
    get very limited use I suspect <grin>.
