Weather resistant version of FA 600 mm Hello I ve put a citation needed next to the about the reported existence of a weather resistant version of the FA 600 mm Apart from that I noticed that the statement is written in present tense but the lens seems to be out of production as of 2014 Instead of searching for a reference for that I suggest to simply remove the FA and put in the rather new DA 560 mm instead It is marked AW so it should have the same improved sealing as the DA lenses have
