OK Clive - you are right!:):)

I have tried it out my way on the 'standard view' from our living room window, for which I usually use FL about 40±, using 3 x FL80 panorama; cut a mask from the latter and superimposed it on the former., then for good measure overlapped them side to side and can align hedgelines etc. I did a bit of scribbling on the geometry too and concluded there should be a small difference in the outer 1/3s of a wide angle, but it is probably less significant than the other distortions ones gets.

So the 'character' of WA shots is as you say derived from the way they are used.;)

And of course the same goes for long lenses :)

I remember we discussed the xy to get the rainbow circular; one of the earliest bits of foruming or comment on WPF I remember:)

Correct. :)
