Interesting Thread with lots of apparently different points of view. I have just been wondering if the points of view reflect our respective situations rather than an objective assessment of the three cameras being compared.
This is what I am seeing as I consider the impact of the D800 on my photography.
I see three positions re this issue (there may well be more that others wish to point out).
1. Those who currently own a MFDB
2. Those who are, or were considering the purchase of a MFDB
3. Those who have no intention or capacity to purchase a MFDB.
So each of those groups seem to have three broad options available to them (again there are probably more but you get my point)
Group 1 who currently own a MFDB have roughly three options
(a) BAIL OUT - sell and move on
(b) RATIONALIZE - defend the current benefits of IQ180 files for example.
(c) WAIT - maybe Phase 1 will bring out a better camera, a bigger sensor etc, etc
Those in Group 2 who are or were thinking of buying a MFDB also have three options.
(a) BE GRATEFUL - Review the savings now possible if the D800 fits their needs.
(b) BE OPTIMISTIC - wow now MFDB will be cheaper and second hand units in greater supply
(c) WAIT - What will the next generation of MFDB's deliver
Those in Group 3 who don't want or cant afford a MFDB have three broad options
(a) CELEBRATE - the D800 is the latest camera with premium performance per $ spent
(b) ASSASSINATE - the IQ180 was King last year but now lets chop off his head
(c) ENJOY - the conversation that these releases engender - and wait for the next killer camera to come along that makes the D800 look shabby and past it's use by date.
I currently own a MFDB and have opted for the WAIT and see what happens next option.
This decision may result in me having the most expensive paper weight in the street.
I respect that everyone has a reason for their point of view - this is my attempt to appreciate the different views expressed in this thread.
