... perspective is simply the human perception of a planer projection
that's why this is both right and wrong at the same time ...

Moreover. If you take a superwide angle pic then print it large and stand real close to it... bang, all the "distortion" is gone!

The Heliar 12f5.6 is different - it is not a "walk about" lens - it is for specific shots. It has a steep learning curve - and you can still screw up - but it is unique in its own right!
This at f5.6, Neopan 400 in Harvey 777, lens on a Zeiss SW.

Another two "problems" that don't seem to be mentioned usually:
1. It's a counterintuitive thing but you should normally not use too wide of an aperture unless all that is subject is far away (or all at equal distance). Things at the edge might be much closer than central objects and will get blurry quickly (or the other way around). You can see a lot of superwide shots with blurry corners, this is not because the lens is not sharp...
2. Also related to the big field of view: the dynamic range of the medium can't cope with all that is in the frame. In most scenes there will be patches of blown-out highlights and pitch black parts in the shots, you just can't avoid that.
Light falloff in the corners just makes the point 2 above even more of a problem.

... yep, I have a 48x72 print and it's disconcerting as one gets close to it

The point with "superwides" 12mm and 15mm is the distance from you to the subject AND also your distance from the print. If you look at the images of these lenses in small format and from distance, they look weird, but if you look at a big blow up and really close, the images look FABULOUS.
