I remember reading in a book (I believe it was one of those Ansel Adams books..) that 
the best way to test for Lens sharpness/resolution was to take a photo of a newspaper 
stuck to a brick wall at a reasonable distance and then check the neg/print afterwards 
to determine how well the lens holds up. 

It was something along those lines.. anyone can correct me on this one :)

Cheers,
Dave

(http://www.popphoto.com/HowTo/ArticleDisplay.asp?ArticleID=193&page=5)
I read the following:

"Whenever anyone asks me how he can tell if his lens is sufficiently
sharp, I tell him (or her) to take pictures with it. Load up with one of
those great ISO 400 slide films, wait for a nice bright day, find a
colorful scene at mid-distance, and shoot away using a tripod. "

What?  use 400 ISO film to measure sharpness???????
