I have been working in Taipei for over a year and I do not agree with your statement that all camera equipment tend to cost a bit more compared to Singapore. I don't know about Canon because I have been a Nikon fan for a long time. The dSLR bodies cost about the same but all lenses, whether they be Nikkor but especially Tamron, Sigma or Tokina cost cost much less here. Likewise filters by Hoya, Kenko and Marumi are also cheaper. For example, the last time I checked the price of a Sigma 10-20 lens whether Nikon or Canon mount, it was quoted at NT$13,500 or about S$643. The Tokina 12-24 is about NT$14,500 or about S$690 and the Nikkor 70-200 F2.8 VR is about NT$49,000 or about S$2,333.
