Oh well, at f/3.5 such things can happen, especially when using a high focal length, which seems to be the case here. But still it is a bit strange, since it is rather the near field that stands out of the DoF.
Anyway, if your lens has a DoF scale on it, or even better if your camera has some capability of letting you see the real DoF at the chosen f/stop, then it is easy to get everything of interest in focus. If there is no such possibility then one can still find the DoF range. Perhapy you might want to take a look at http://www.dofmaster.com/hyperfocal.html . Much useful inforamtion there.
Thanks for your comments on my photograph. I'm not quite sure why the top portion of the photo came out a little fuzzy. I thought I was focusing on the center part of the picture so I would get the entire picture in focus.
What an idea and what a fine implementation! The whole complosition acts more than an abtract in X-like shapes, that cross each other again and again. And the well chosen combination of colors does the rest. Excellently seen!
Perhaps some small sharpness problems at the back, but othewise a very "refreshing" one!
