Re: Perspective ala Canon? (TECH-3D digest 223)

RE: John B. and Eric G. comments on super wide and old Canon lens 
book that thought 100mm saw the "way the eye sees"..e.g. mostly 
central sharpness surrounded by aware blurry motion detcction field.
I just looked in the snazzy new book, that is equivalent to the old 
Canon Lens book of 1965 or so. It is: Canon  LENS WORK  EF Lens Work 
II. Available in camera shops for about $25 as I recall. I find it is 
back to the 50mm lens as having the perspective most people find 
normal. In long list of lens picture examples is says simply: 
"Remember short lenses exhance perspective and long lenses flatten 
it."
But it is a very interesting book and has managed to fine and even 
earlier Kwanon (1st Canon) without the dreaded Nikkor lens. This one 
has  a "Kasyapa", that other wise is a dead ringer for the f/3.5 
Elmar, complete with Continental markings of f/3.5, f/4.5, f/6.3, 
f/9, f/12.5 and f/18. What we are familar with today is the "English" 
System. German lenses before WW2 had the other marking if not for 
export. The headline that got me was "Canon's first 90 million 
lenses!" 
The book has super illustrations of every current lens and many 
diagrams and cut-aways and optical discussions too. Worth the money.
