Is the pentax hd d fa 15 30mm f 2 8 ed sdm wr weather sealed?

The name ends in "WR", but the spec list on this lens's page doesn't spell out weather sealing, so I wouldn't rely on it for rain until you've checked Pentax's own listing.

If wet conditions are the reason you're asking, that matters most for landscape work. You'll be out in wind, spray and drizzle at dawn, and a sealed body and lens are what get you through it. My Landscape page covers what to look for. The lens fits the Pentax K-1 and Pentax K-1 Mark II, both full frame, so check the body's sealing alongside the lens's.
