AFAIK, Sigma has only now started to offer such feature in their lenses. And I'm still unsure how "WR" a "splashproof" lens is supposed to be. Note that Sigma is the largest third party DSLR lens mftr today and they also led in the introduction of optical stabilization and silent focusing motors. So the situation in Canon/Nikon land as far as 3rd party support is concerned is not better than for Pentax - and it cannot be, because WR was a feature reserved for high-end cameras until just recently. It's probably not a coincidence that Sigma is introducing these designs at a time where Canon and Nikon also introduced more affordable WR bodies.
