No. DOF preview merely activates metering, so you can see how the set exposure differs from what the camera thinks the exposure should be. (The *ist-D does exactly the same when you activate DOF preview). [Well, they both stop the lens down, as well. I hope that's obvious :-)]
Pushing the green button on the *ist-D (or the AE-L button on the *ist-DS; apparently this is documented in the manual, just not mentioned in the index) stops down, then sets the shutter speed based on the camera's meter reading.
