Quite right. That is why when a (Pentax) Full Frame digital body comes out I would ideally like to keep the *istD. That way I can use it for telephoto shots and the FF body for wide angle. When my wife and I used to go travelling we always used to have 2 bodies, so that one camera would be fitted with a wide angle zoom (Tokina 19-35) and the other a longer zoom (a M75-150/4). Also I would bring along a A50/1.4 for low light shots. Trouble is that *istD and DA16-45 were so expensive I had no choice but to sell off all my film bodies and most of my lenses to pay for them.
