I bought it from the 2nd hand market
(I tried to find this lens, which Made in Japan, however did not success)
It's around $ 2500 ~ $ 3000. the one I have, it is pretty good condition.
Even, it's not "II" version
Still worth to pay @ $ 2.5K(or bit more); wonderful for travel
I'm happy to buy this version
(instead of version II... that's more than $4K (in 2nd hand market))
