It's very difficult for most lenses to look bad contact printed, or enlarged 3X; the smaller the film got, and the more it was enlarged, the more the characteristics of the lens were exposed; so along with the interminable push for more sensitive and finer-grained films and developers, the "cult of lens quality" emerged." "Never be blinded into thinking that good tools = good work. The world is full of photographers who churn out sharp but wretchedly poorly-seen pictures. They can break their own arms smugly patting themselves on the back for owning the latest apo-this or aspherical-that, but regardless, Johnston's eighth law still holds: crap is crap."
