Originally posted by angerdan Some indicators:

For the D FA* lenses they do as well as for the FA Limiteds
That the DFA15-30, 24-70 and 70-210 are licensed from Tamron is not in dispute. Thanks for the good indicators @angerdan. That is why I don't have them. The DFA*s 70-200, 50 and 85 are in house Pentax designs and it is the reason why I currently right now have 2 out of the 3 in my bag, soon to be rectified to 3 out of 3. All very black and white, no grey area. You could say I'm a lens snob, a Pentax purest - I do have too other lenses from other brands, a Zeiss and a Leitz which I consider being of the same stature as Pentax as optical design houses.
Now for those that doubt it, please stop trying to dilute the design providence of the DFA*50 and what is sure to be a class leading DFA*85 in the sub €3K range, which have both been researched, designed, patented, manufactured and sold as Pentax, part of Ricoh Imaging.
