I forgot to mention this on some of the earlier threads concerning old vs new lenses. One of the reasons why many of the early pentax lenses ( late screwmounts and early K/M) mounts are so damn good is due to sample to sample variations ( or lack thereof! ). Not only was the build quality higher throughout the entire lens lineup, but along with it came better MFG quality and quality control. It doesnt matter if you have the worlds latest and greatest optical designs if you cant build them consistantly.
Does anybody remember the special feature the Honeywell Pentax screwmount lenses had in this regard? ( this isnt a question I need answered, this is a quiz to the listers!).
