you LHSA types out there check Brian Bower's article in the 
current VIEWFINDER Volume 32, number 2 and tell me 
something. Is the lower picture on Pg. 18 showing the curvature 
of the earth that is apparent with a very wide lens from such a 
wide vantage point or is it a bit of expected barrel distortion from 
such a lens, OR, a combination of both?

I guess my question is, how rectilinear is rectilinear? My guess is 
that the lens in that shot was set up pretty plumb.
