 I suppose if I was guessing then I might say for 600mm, the following IQ ranking might apply. The cost of each combo is shown and I have ranked the costs.

600 + D4............................................ = 11400.......1
600 + D800....................................... = 7900.......7
400 + D7000.................................... = 6500......8
400 + D4 + TC1.4............................. = 10700.......2
400 + D800 + TC1.4....................... = 8200.....5
300 + D4 + TC1.4 + crop................ = 8700.....3
300 + D800 + TC1.4 + crop........... = 6200.......9
300 + D7000 + crop ....................... = 4500......11
300 + D4 + TC2.................................. = 8300.....4
300 + D800 + TC2............................. = 6200.......9
200 + D7000 + TC2.......................... = 4200.......12
200 + D4 + TC2 + crop...................... = 8000......6
200 + D800 + TC2 + crop............... = 5700......10

From this list I would like to know ...do the D7000 + 200 + tc2 or D7000 + 300 + crop have significantly poorer IQ than the D4 & D800 combos? Because, despite the simplicity of using just an FX sensor and cropping ...the finance doesn't stack up???
