How and why does lens manufacturers manage to make dogs? I mean bad lenses, of course. Dogs and excellent lenses often seem to cost the same ammount of money. Does company policy allow dogs to be made from time to time or is there seroius flaws in the the company testing and quaility controle procedures. Does the engineers cheat their superiors? Or is it an exceptet company policy, that it's OK to release a bad lens once in a while? Or is it in fact pure luck, when Pentax from time to time manage to produce a single outstanding lens - like the A*-1.4/85mm or the F-1.4/50mm or the FA 2.8/300mm or. Well - these are all pro-type lenses - but what about the F70-210mm. Why is it so well made. I mean - the FA-version sucked big time!
