Well, being excited about and wishing for new gear is not quite the same as saying you absolutely need it for a given job. Sure, with the right settings, technique, and coupled with the right lens, it is possible to pull off pretty decent action shots with the classic K-3. But the keeper rate could be higher, and if your subject is moving at anything more than a leisurely pace towards the camera (think, children or pets at play), it's getting kinda hard to achieve anything much that's critically in focus. (At least, that has been my experience, even if my screw-driven AF lenses were not particularly suited to the task.) For the pic of the dolphin, I prefocused my non-PLM 55-300 and otherwise waited till the animal changed its course to sideways, before I tracked it in a burst of several shots. If the K-3 III actually made this kind of shooting a little easier and more likely to produce in-focus results, that wouldn't be a mean feat, in my book.
