Okay, math whizkids, how comes it that Leica (and Canon) can make an f1 50mm
lens, but no one can make an f1 wide angle lens?  I should think it would
get progressively easier (and smaller) to make an f1 35, or 28, or 24.  But
you get down to 24 and the fastest lens you can find is the Canon EF
24/1.4L.  How come?

Curious,
Dan
