sadly no - it was only in that section of the manual. - I can't spot the difference between japanese and chinese... I just don't get eastern languages
is is clear that there is lead used in the, how much of it there is and the components that contain it is the question.
ED: I went through current European WEEE/ROHS legislation -
you guys owe me hugely for that - and photographic optics are not on the exempt list - so they have to conform with ROHS guidelines by using reduced lead content in optical glass.
According to the guidelines in ROHS II - established December 2012:
"...lead, mercury, hexavalent chromium, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs), the maximum concentration is 0.1 % by weight in all homogeneous materials..."
So the bottom line is that Pentax would still have to re-design all their older lenses if they wanted to re-make them to be able to be sold in the EU.... or anywhere else for that matter.
