I suspect that there is too much volatility in exchange rates to set prices far in advance of actual availability, if the Yen gets stronger against world currencies, prices will need to somewhat match.
Having been the guy charged with eliminating foreign exchange risk for a multinational....
We buy/sell positions in currencies all the time - based on sales and purchase (raw materials) expectations over time, some of the purchases or multi-year horizons, some are a few days.
Having said this, the product managers set the price to maximize operating profit. Any competent exchange rate manager would have exchange risk down to less than 1%. The goal isn't to make/lose money in the currency transaction per se, it is to reduce such volatility in the P&L. Every so often the ex manager gets it wrong and is long/short on a rate and either the P&L takes a hit, or the product manager has some flexibility to lower price - generally the company is slightly biased to use favorable events to expand market share and move product. So in the moment, it is how much money the product managers think they can separate from you.
So prices might vary a bit between countries, not so much for exchange rates, but if the product managers think a couple percent difference price might move more units - or upped a few percent the same units would move regardless - somewhat a local economy issue. With ebay and very rapid grey markets, this has been tamped down a bit - in the olden days one might lower the price in a depressed market - now that just means they would buy in the market and arbitrage on Ebay.
In the end, it is only about the money and how smart, highly trained biz types try to collect as much as they can for their side - which isn't yours.
Back to the photo stuff - I think Sigma had done a marvelous job in creating a very valuable lens product line. If one is happy w/ a crop sensor IQ (getting more so every day) take a moment to stage out the focal lengths and f stops of their crop zoom offerings, and mix in a couple of their FF lenses. WOW is my reaction.
I am hoping that Canon (and less so Nikon) up their games likewise. It would be an interesting branding thing if Sigma went with a lens color for their art series - Canon has the big white w/ red ring for example. Soon, you could have the snob appeal of having a sigma 85 etc that people could see because it was some special color layout.
