According to the official information published in various different Pentax websites worldwide, only Pentax Imaging is still selling the DA16-45 in the US, whereas for all other countries the DA16-45 is not listed, including the Japanese Pentax product page. So, people are suspecting it was discontinued and only Pentax Imaging (US) has been selling (all) the remaining stock. Now, the above shows that at least the rumoured discontinued DA1645 lens is actually still in production. So, the Pentax DA lens lineup is not dying, as the first DA lens is still being made! ;-D
