checked a couple of sites this week and found price of 6D, 7D, Sony RX100 price going up while yen is going down ? anyone knows why ? logically, the price should be going down since SGD is strengthening against the yen. for example 1 sgd = 70 yen in january 2013 and today its 78 yen. sgd is up 12% so why is price of cameras not going down ???
