Point taken. However I don't believe that all modern Pentax lenses are devoid of optical plastic. Nor do I think that all the lenses that Pentax marks as having aspherics is made by crafty glass processing techniques, especially the inexpensive ones...

Yes and no -- real glass requires real weight and bulk.  I agree that
most people (who don't care about DOF, macro, or large prints) will
stick with phone cameras.  No surprise, really.


Not to mention: sharpness, contrast, colour, and all the other quite
significant qualities that precision glass has over plastic lenses.
