Originally posted by Thomas I do have a 645D, since Dec 2010. I too took a gamble pre-ordering the 645D when it was released in the US; I was using a 67II, but film was becoming a real problem for air travel (ironically, I haven't done much since). You may remember that I notified you about the 600mm polarizer. The high ISO of the Z may be enough to convince me and a used D is worth so little now, it's a good back up.
I knew you were familiar; I couldn't remember if you had sold me something or I sold you something, etc. I am still in debt to you for finding the polariser. I would have missed a couple amazing shots without it.
Yeah the 645D has fallen a long way from what we paid back then hasn't it. It seems used in conditions like mine at least it goes for about 3,500. Not justifiable for me to sell having spent 10k on it plus 1k in shipping to me over there...
What a bargain though if you want the 645D now. So to the original poster I would not hesitate to enter this market at current prices. There will always be that trade off to the high res 35mm bodies but I have never looked back from my change. I often contemplated the switch back to 35mm when the D800 came out; but, still to this day don't regret sticking with the 645D as it would have always been in my kit and stayed the primary use. To each his own. Live view on the Z is another plus. I often dreamed it would be nice but never had an issue (have the focus magnifier to aid focus confirmation on the D).
Someday I may get tired of hauling the weight around compared to other decent more compact options but that isn't today and won't be tomorrow.
