You make a point Keith, but I think one of the problems is many people use relatively long lenses for Panoramic shoots which of course flattens out the scenes far more than a wide-angle.

I deliberately bought a 75mm SA to use with my 617, I had also intended to use a 90mm but found I never used it. My rationale for the 75mm was that it was close to a normal lens for a 6x6 and therefore the vertical dimension of the 6x17 format while wide angle for the width. In practice for my requirements it seems a perfect balance for the format.
