The Canon also is weather sealed.

Sigma claims sealing for the 150 OS, too.
Regarding the discussion around 150/180 mm: the 150 non-OS felt more like a shorter lens (physically, which means: in the bag). That's the biggest drawback of 180mm lenses IMO, they are significantly larger than the Sigma 150. Or to put it differently: that's what probably made the 150 so popular, it's quite short for such a long lens.
