    Is there any recommended configuration for the above ? Couldn't find the lens in the port charts.

    I would like to use the compact dome port, but not sure which extension /

    Thanks

    Japan has not tested this lens, however, based on the specs we would recommend using the NX Fisheye Dome #56401 or you could consider the SX extension Ring #50261 plus the NX Compact Dome #56601. A gear might be close by using the 31107 12-24 Nikkor gear. The lenses are close in dimensions Tokina = 84mm (D) x89mm (L), Nikkor = 82mm(D) x 90mm (L).
    Again, these are not tested and verified, but you could certainly extrapolate this info and test image quality/fit for the gear etc.

    We have set many people up with this lens in Sea and Sea housings. I always recommend the NX fisheye dome port over the other compact dome ports for the best image quality.

    Extension ring 40, +2 diopter with the NX fisheye port, or +4 diopter with the compact dome ports. There is no gear available from Sea and Sea, but we have machined a gear to fit this lens.

    Best regards,

    Thanks Jim - How much would be the gear you make ? Would you ship it to Singapore ?

    Thanks - I do have a compact dome port and SX extension, but the lens is very close to the port (not even sure I can add a diopter). Would I get decent results with this config, or do I need to get the 40 exension ring ?
