It seems that I have been quoting the PF more often recently, but FWIW:-

In short, the DA*16-50 is now for $1424, the DA*50-135 is $1524, the DA*60-250 is $1899, for instance! Well, these prices are utter non-sense after all! I now know why PF seems to be angry with Pentax these days! If this trend continues, who will buy more new Pentax gear? And how PF could earn a living as nobody to buy the gear via them and affiliated shops online?! :-o I am almost sure that PF had the figures in their hands how those Pentax sales are dropping..
