I've got a lot of crystal clear photos with SR on. Do you have test images or can you point to any test on the web that shows that SR degrades image quality when using a tripod? I'm particularly interested in this comparison under the conditions in which I and many other people use a tripod -- panning the camera and firing quickly to catch wildlife, and using a light carbon fiber tripod that can be transported into the field. I note that Nikon's long lenses have a vibration reduction mode for tripod use, so it can't be that SR on a tripod is always a bad thing. But the Nikon VR system is very different than Pentax SR. So I'm interested in actual test data with Pentax SR under field conditions, not theory.
