The reviewers I have seen have found the K-1 not great with tracking an approaching subject like someone running or a car driving towards the camera. That may be the kind of tracking that the K-1 might struggle with.
i find the comments about focus tracking on moving objects curious. Many years ago, when i bought my PZ-1, it had a feature linked to the AF and Power Zoom called image size tracking, using predictive autofocus to not only track the focus of a subject, but also move the zoom so the image remained scaled / framed as intended even though it was coming towards you.
where did all that software from the PZ-1 end up? in the trash?
the only time i saw that system confused was when i put my daughter on a swing. it just couldnt cope with cyclic motion.
but the point is, it is not impossible to deal with isubjects coming at you, only that since focus is non linear (i mean look at an old mf lens, from infinity to 10 meters is a 1/4 turn of the focusing collar, and from 10 meters to minimum focus is another 1/4 turn. so the rate of change of focus adjustment needs to be faster when the subject gets close, but otherwise is it that hard?
