Average wage in Vietnam is 392$/year based on the link provided, so buying 1500$+ lens is highly unlikely but possible I guess...
lol, you have no idea. Average, sure but there are weathy people living all over VN. A Mercedes here costs $85K but there it's more like $150K and I saw plenty. VN is not some destitute place, it's a wonderful young country and coming into it's own.
Oh I'm well aware... I lived in a former socialist country where my uncle sells a pair of shoes for
350-1200euros, yet he pays his employees 100-300$/month... with an average yearly salary under 2k a year.
I go back there on regular basis and besides the professional hired photographers at fashion shows, my D90 stands out and often I feel uncomfortable walking around with the camera on my shoulder.
Also, I've seen more Ferrari F50's and really expensive exotic cars driving around the streets of Bucharest/Romania in any given summer month than I've seen in Vancouver/Canada for the past 10 years, so yes I have some fair ideas; not to mention the roads in Bucharest are terrible and full of potholes.
That's why I said unlikely but possible
which brings up another question in regards to your comment; if money is no object, why look into buying used expensive pro lens from a different country for a D3100? If the OP drives a 85k Mercedes, he would not play with a 500-600$ entry level DSLR camera and wanting to pair it with a 1500-2200+ pro lens...
Not saying the buyer is not genuine as I have no way of knowing but in my eyes
this scenario is more plausible... not to mention I am really skeptical when dealing with buyers overseas.
Just my two cents.
