  1. I have not used this particular combination but I have done full frame fisheye transformations with a 16mm fisheye Nikkor on film using panotools.

     

    The lens has a 180 FOV on the diagonal and when I transform it to rectilinear the HFOV is about 145 degrees.

     

    The transformation may result in unacceptable distortion at the corners depending on subject matter and your standards. Think about painting a circle on a rubber canvas and then stretching the corners out (way out) until the circle becomes a square. The corners have been stretched and the software must interpolate the pixels. The line which formed the circle would be uniform width but when it is stretched to form a square the line at the corners will be thicker. For some subjects - such as architecture - this may be unaaceptable but for tothers such as landscape or abstracts it might not matter.

     

    Be certain however that the results will not be identical to using a rectiliner lens.
