I could take a panoramic photograph with a 30mm, 45mm or 90mm XPAN on 35mm film, if I had the XPAN camera.

OR

I could take a 38mm SWC, 50mm, 80mm ... Hasselblad lens, and make a 56mm x 56mm negative and crop it to 24mm high, the width of a 35mm film and the would still be panoramic photographs, right?
