    I have find some time to determine the optimal setting for Sigma 8mm F3.5 Canon and Nikon on R1.
    Here is a table to show the settings.

    I would appreciate if users can test the validity by making a pano using my value(s).
    I will make integrated rail plate for selected tilt angles. I will give 10 free copies for responders (one each) of each mount. $10 in value.

    Nick, I think there is an error in the figure given for Nikon 0 degrees, 4 shots around. 3.8 should probably be 2.8 as the Canon and Nikon figures ought to differ by 0.6 (approx) throughout.

    Hi John,

    Thx for the input. The sigma 8mm for nikon uses LRP45X which extends 1cm to the back. So extra value of "1" is added compared to other LRPs. This plate is used for Tokina 10-17mm if you still keep it.

    Nick, I don't understand your repsonse. I was simply saying that the Nikon figures should be Canon + 0.6. The figure given for Nikon 0 degrees, 4 around is 3.8, whereas it would be expected to be 2.8 on this basis.

    opps, you are right. I probably made a mistake in data logging. I will double check.

    what a coincidence with LRP45X difference.

    Are the values for Nikon now correct in the linked table of the first post?
