A 15mm (ASP and non-ASP)

[Andre Langevin]

As we are talking about the 15mm, and some Takumar and (few) K lenses 
(not A) have an aspherical element, the japanese Pentax Lenses Study 
Group seems to give a way to distinguish the aspherical lens fron the 
non-asp.

The feet indication on the ASP would be 7, 4, 2, 1.5
The feet indication on the non-asp would be 7, 3, 2, 1.5
I don't know if this works out also for the Takumar lenses.

To me that seems to be a "typo" on the lens barrel as the 4 feet mark 
on the ASP lens is at the same place than the 3 feet mark on the 
non-ASP, that is in front of the 1 meter mark.  Since when 4 feet 
make 1 meter?

But there could be a better way to know which lens is ASP:

Is there a better tool than Babelfish to translate from japanese to english?
