Re: 36mm x 36mm sensor?

[Gonz]

I've seen some lenses with rectangular shaped cutouts in the back, so 
those probably wouldnt work.  And then there are hoods designed with the 
image rectangle in mind...

Since the "full-frame" discussion re-emerged yet another time earlier

that be the "ultimate" size for a 35mm body and lens? I mean, the 
elements being circular, surely the lens should handle the same size 
along both axes?

Of if you simply like rectangles, how does 31 x 36 sound? (Same ratio as 
6x7, more or less...)
