Similar to Hong Kong or Japan there is a rather large camera district that stretches about 2-3 city blocks. Large picture display windows with every kind of camera you could imagine. All trade ins are usually welcome. Its so convienant that you could try a 70-200mm lens for a week and decide not to like it and trade it in straight up for the similar pro glass 24-70mm if thats your thing. All kinds of used equipment in great shape to. Leica Mp4, M6, M8! M9 already in stock. Classic Nikon bodies F4, F5, even F6. Hasselblads you name it. Used D700 but around $2400 same as Canada or Ebay. They have certified Nikon shops for cleaning and repairs located in the same district! Any Nikon with a Korean warrenty is more expensive than a Japanese or International warrenty. Prices be changed shop owners are reasonable. Think Western style shop keepers not Vietnam or Thailand bartering. Unfortunately filters, are a little weak here, but accessories like bags,straps, tripods are good. Loupes, and other eye gear are Ebay items. We do have B+W filters though if you look hard enough. Ballheads are not good here either. Gitzo, Manfrotto, Markin ballheads but forget Really Right Stuff,acratech for here.
Lens shopping is a real treat. I found lots of goodies like my Nikon 35mm AIS lens or my Zeiss F2 35mm. Difficult to find 11-16mm Tokina wide. They always have items in stock. I guess what I'm trying to say is if you visit bring lots of cash haha I have to control myself, but like I said before I'm just a 14-24mm, teleconverter and FX body away from being complete. Oh and they even have lots of Velvia 50 film!
