Questions about OM System M.Zuiko Digital ED 90mm f/3.5 Macro IS Pro

Does this lens have an original CH warranty, I don't know if anyone here knows Achim Kluck on FB, I have never seen better macro shots, of course he also stacks, but unlike others with natural light and not with flash and some kind of diffuser construction, just impressive what he gets with this lens and the OM-1: https://www.facebook.com/achim.kluck
