That's true I don't think I've been clear enough about the Z4s capability.
You can get 4000:1 - 7000:1 (filtered and unfiltered from the Z4) no problem - that is if you are happy with one of the MORE dynamic modes that allow the Iris more freedom to hunt in the picture. This is my objection. If you are happy with the IRIS closing right down in certain scenes (sometimes the wrong scenes) then you can get these numbers.
Let me draw up a list: (BOTH UNFILTERED)
Least Iris Movement, least contrast best color balance and decent gamma.
LIVING (though gamma is iffy here)
CR (between 1000:1 and 1300:1)
Most Iris Movement, most contrast, work on color balance needed, dicky gamma.
CR (between 4500:1 and 6895:1)
Irrespective of whether you filter or not, you're still going to get Iris movement in the higher power settings.
The Z4 looks to have good ANSI contrast so makes up for outright ON/OFF contrast in my opinion.
I have yet to move on to filtered calibration as it's nice to see what It can do without filters first.
