Sigma DP Merrill Series; how to calculate stitched wide angle equivalents?

[Ligament]

I'm sure there is a calculator out there somewhere, and possible one of the Lula members authored it ;-)

I have the DP1M, DP2M, and DP3M Cameras.

Lets say I want to stitch images from DP3M to simulate the view I get from my Nikkor 14-24mm f2.8 lens at 14mm.

How many panels, in which orientation, with how much overlap per panel is ideal to simulate a 14mm view on a FF camera?

I'm sure there must be a way to calculate but I'm not clear on how to search for this type of maths.

Thanks!

It seems grossly the horizontal FOV's are 14mm 104 deg FOV and a 75 mm has a 29 deg FOV, in other words, you'd need to rotate through about 4 exposures of the more restricted FOV lens to achieve the same wide angle view.

Though I am curious why you'd strictly want a 14mm FOV, wouldn't the unique scene dictate the number of panes ?

Thanks capital; I don't strictly want a 14mm FOV, but was using that as an example and point of reference. Ideally I'd like to be able to calculate this for any FOV. Good question :-)
