Very often I am thinking along the lines of who cares, if a price reduction pops up in the U.S., but for this lens the price reduction is similar in Switzerland, where I live, although not quite as low. Currently the price is at 1419 CHF or 1531.75 US$. In previous years prices were around 2000 US$. You probably still can find some crazy places in Switzerland, where they try to sell it for up to 2500 CHF (almost 2700 US$), although Canon's official price lists it at a little more than 2000 CHF, which would normally correspond with a market price as low as it is now.
I don't know what the reason is for this, though. Since this is Canon Rumors, perhaps it is time to speculate regarding a 50mm f1.2 Mark II coming out?
