I forget which tax...but you should be able to figure out 105-12 = 93 (93/700) * 100 = BOTH.
assuming ~700 for the lens, plus the rest to = `800. I forget the exact figures, but I know it added up to approximately 800 bucks..and it was 105 ...12 being duty.
Hope you figure it out.
Ends up being almost the same price as Henry's...
