Frank, are you serious? For the D700 the DOF at 3m stretches from 1.08m to infinity with a 20mm lens at F8 <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/ohmy.gif' class='bbc_emoticon' alt=':o' />
At F11, your DOF goes from 0.9m to infinity!! What kind of landscapes are you shooting if your DOF is not long enough?
I have done some research on my own shots with a 35mm f2 and the different landscape shots I have done; at F8 my hyperfocal distance is at 5.14m, so if I want to have absolutely the whole picture in the DOF, I just focus at 5.14 m and the picture is sharp from 2.7 m until infinity!!!
Maybe you should look at the way you focus, if you have a problem with a 20mm lens at F8!In your picture, if you focus on the third stone, your whole picture from the second stone to infinity will be sharp and the the first stone will be almost sharp.
Now, with respect to which lens to choose; I am going for the Nikkor 20mm, just for that reason. Resolution becomes a no brainer in landscapes and architechture with that wide a lens. Just stop down and you are fine. I have looked at pictures shot with the Nikkor 20 f2.8 and as of about 5.6 it is glorious, both in colour and resolution. Are there better lenses theorethichally - yes for sure if you wnt to shoot at 1.4 and 2 and even 2.8, but who does? It is hard to beat 500€, 240g and Nikon quality, plus AF and you can use a polariser that costs 50€ instead of 150€! (Hoya Pro slim) On a 14-24 goodbye to filters and hello flare! The Zeiss is very nice, but look at pics of both and tell me you can see the difference if you stop down and focus correctly! For the money for the Zeiss, I buy a 20mm Nikon and a 24-120f4 Nikon!

Hi Vieux:
Thank you for your kind comments and suggestions. I think I need more practice to get appropriate DOF handling. I am considering to download a DOF calculator software to my Nokia cellphone. Sometimes calculation is needed for me. And yes, focusing at the right place is also crucial.
Regards,
Frank
