In Pop Photo (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??????? - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
