Considering the move to a D800. I shoot mostly landscape.
Where I am needing to use say f11 for the DOF I want with the D7000, what f-stop do I need with the D800 in full frame mode assuming I want the same image view and DOF? This would assume say a 24 mm focal length on the D7000 and about 36 mm focal length on the D800. Do I now have to use f13, f16 or thereabouts to get a similar DOF on the D800 that I get with f11 on the D7000?
In the circumstances you describe - the same field of view from both cameras (with the additional caveat that you view/print the whole image from both at the same magnification) - you would need to shoot an FX camera at f/16 to deliver approximately the same DoF as a DX camera shot at f/11.

Thanks, Brian for your confirmation and HGhave for the calculator.
Thus if I make an 12x18 inch print of the identical looking view from each camera (24mm lens on DX and 36 mm lens on FX), I need a smaller aperture for the D800 to see the same depth of field as with the print from the D7000? Just checking if this is what you mean by same magnfication, Brian.

This is the one issue, other than the weight of the top notch FX lenses, that is holding me back from the D800.
If the D7000 could focus better in lower, and/or less contrasty light, had better bracketing capability and used a better arranged remote cord, I would be very,very happy with it. Other than what I list the camera is just great in my book. D400 maybe someday????
(My remote cord problem is the location of the socket in the camera and the use of the RRS L bracket.)

Jerry, I'm not sure what the drivers are that influence you to want to replicate the same DX FOV and DOF with the D800 FX format. If you want to do that explicitly, but with the D800 , you can choose DX format for the D800 image area.
But I thought for landscape, wider was better. If you have a 24mm lens, why not capitalize on the 84 degree angle of view rather than the ~ 62 degree AOV at 36mm
Replicating the DOF as well, gets you to f/16 where diffraction may be an issue as Randy pointed out. I have no idea how far away you like to place the subject (focus point) for your landscape photos. It seems to me, you can use a DOF calculator for your smartphone to manage DOF. If you like to use a 24mm @ f/11 for landscape and focus far (200 ft, say), DOF for the D7000 and D800 are nearly a wash (8' min to Inf for DX and 5'5"min to Inf for FX). Some like to emphasize a near subject stretching to a far background for landscape. Say you used the same lens/aperture setting with focus at 8', DOF extends from 4'1" min to 155' 3" (a total 151' 2" DOF) for DX and 3'4" to Inf for FX - seems like an FX advantage to me.
Hope some of this helps as you consider your choice - (edit) see you made THE choice.

On the weight issue, I have very recently bought the D800, but kept my D7000 for now. I only have FX lenses, mostly pro, and I much prefer the balance of the heavier lenses on the D800 as I did with my D700. For landscape I use the 16-35 f4, 24-70 f2.8 and 70-200 f2.8. The balance will be even better when I get the MB-D12.
For my landscape shots I tend to use a tripod anyway. I'm no youngster, but using my landscape FX lenses is not too uncomfortable hand held. However, using my Sigma 50-500mm for my wildlife shots is starting to become difficult handheld over prolonged periods.
Yes I would agree that the same lens on a DX camera would have the same DOF as it would on an FX camera.
However, to get the same image, or near same image composition, from the same spot would require a 16mm on DX to get the same view on DX as a 24mm would get on FX. That is, if I am understanding correctly.
Thus wouldn't the 16mm on DX give a little better DOF than the 24mm on FX?
