I'm just trying to figure out if it's worth ordering from B&H, shipping to Canada. I'm looking at ordering a Bigma 50-500. I checked this link, and if I'm reading correctly, lenses do not have a duty tarriff attached. I assume I would just pay regular GST/PST on it? http://www.cbsa-asfc.gc.ca/trade-commerce/tariff-tarif/2008/01-99/ch90-eng.pdf Anyone have experience ordering products from BH to Canada?
