There's one thing you should be aware of regarding DOF: it's not for pixel peepers <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='
' />
DOF calculators (or hyperfocal distance calcs) assume a normal print size and according viewing distance to give you a guidline about sharpness, or to be precise: just acceptable unsharpness (is this an english word? ok: blur). If you look at your image again from this perspective, you've already achieved that.
If you want to have a scene like above sharp on the pixel level (from rock to trees), you'll need to think about a tilt/shift lens (in your case the tilt part of such a lens). However, handling such a lens requires some practice, too.
Apart from that, the Zeiss 21 is of course a very fine piece of glass. Personally, however, if I needed a really fast wide angle prime that can also do landscapes, I'd rather think about the AF-S 24/1.4 instead. (edit: or the upcoming Samyang, yes)

Thank you very much for the clarification, Markus. I know that the usual definition of DOF is for a normal print size viewed at an according distance. So in my previous reply I said to use a DOF scale as a "reference". Of course for viewing the picture on the display the DOF is another (more comlex) matter, and if one wants the picture to be sharp from near to infinity at the pixel level (perhaps this is not necessary at all) then perhaps a much larger DOF is needed (depending also on the pixel size of the display, right?).
A tilt/shift lens is charming. To be honest, I am not a serious landscape photographer (at least now) although I love to shoot landscape, so I am not considering to buy a tilt/shift lens (it is expensive and operationally complicated). However, I am curious if the Nikon PC-E 24mm f3.5D is also a stellar lens, I did not see a review on it here.
Yes, the Nikon 24mm f1.4 is very attractive to me, but it is also very expensive. I would wait and see the Samyang 24mm f1.4.
Best redards,
Frank
