Specifically on TS lenses, to me it seems traditional simple DoF considerations seem inadequate an expression. Particularly for a landscape application where the subject is often on a plane from you to infinity, you could say the effective DoF, at least for the subject, is infinite if you put the cone of focus roughly from yourself to infinity, and the OOF areas would be put out of shot.
Hmm... I probably should rewrite that but I haven't had enough coffee yet!

You still have to be careful with selectively positioning the plane or wedge of focus. I've seen a few mountain landscapes which at first glance seem to have DoF from closest foreground to the furthest mountain top, but then you suddenly notice why the image feels awkward: the valleys between the flowers in the foreground and the mountains in the background are not in focus at all <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='
' />.
What I wanted to say in my statement is that you do not so much get more DoF, but that you can selectively place the DoF plane or DoF wedge (almost) anywhere in the scene in front of the camera. That has advantages, but also risks <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />.
However, I do recommend them to anybody who is prepared to learn to use and understand them, they are really magnificent tools! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' /> And when it comes to the two latest releases by Canon (TS-E 17L and TS-E 24L II): I don't think there currently are any better lenses out there for use on FF, APS-H or APS-C.
Kind regards, Wim
