You are treating the image as if the 104 degrees of the 14mm lens would be distributed
evenly over the 6000 pixels ... would that be the case, your calculation would be correct ...

Good point... I was afraid this was the problem. Thanks for clarifying it.
Are all rectilinear lenses made the same? I once compared the standard 24 1.4L II against unshifted/center of the TS-E 24 3.5L II (which has a much much larger image circle) and was surprised to see that even the rectilinear/volume distortions were identical between the lenses. Wonder if the same holds with other lenses (ignoring barrel distortion), especially for lenses from different manufacturers?
