i'm not a MF shooter, never been; just a 35mm film and APS-C shooter.
I've read all those post because the title catched me
when i read this thread i've realize they were 2 groups of people : real MF shooters and the others. And i consider that Chicagonature belongs to the second group.
Chicagonature, you seem to consider the 645 system like another 35mm system. Obvioulsy it's not.
You can't compare 645 and 35mm only on paper spec ! Because beyond number, that may now appear as close, in use there is such a huge difference. You discuss about the difference like i discuss about the difference between a D5100 and a K-r.
You are asking "should i buy the 645D ?" the answer i give you when i read your posts is "nop", because in fact you don't seem to want it or even need it.
What you are looking after through the 645D is a kind of 1DX with a 60Mpx or more, that will give you a 645 rendering-like, or something alike.
the question you should ask yourself is :
- Are you happy with your set up ? If yes, why change ?
- why do you need something newer ? will the "newer" will give you real improvement or is it just because of "numbers and paper spec" ?
- Will it meet your needs ?
You are not looking at the right things, and asking yourself the good question to me.
Just my 2 cents...
