That "WR" designation first showed up on the D-FA 100mm macro I
believe. It's a much more recent marketing finesse anyway.
My D-FA 100mm ƒ2.8 Macro has a hard plastic mating surface to the camera, and
no mention of WR on the body or box.
Ser. #5826425 49mm filter. Clamp on-off sw.
as you may know, there are two D-FA 100mm f/2.8 Macros; the initial version
(yours) with the wider focus ring; and the subsequent WR version, with a
narrower focus ring, no aperture ring, and "WR"; the best used prices put the
WR version $150 more
i'm well aware of the differences as i am attracted by the lighter weight of
either of these (vs. my Sigma EX 105/2.8), and it's been hard for me to weigh
the trade-offs between the two
