Couple questions about AF tracking: 1) I've got it set up on to start C-AFtracking with a half shutter press, and doing so with my (admittedly crappy) old Panny 12-42 kit lens (only one I have at the office right now) it seems like A) it makes the screen lag a bit at first, and B) it seems like it doesn't really hang with the thing I initially focused on. It also seems like it never really "gets" focus - it just hunts (as I assume it's supposed to) but I keep getting blurry pictures. Is any/all of this normal? 2) Which burst mode is best to use for C-AF tracking? Will it work with the "H" setting? I've tried it but I can't really tell if it's not working or if it's just missing a lot in this relatively crappy light. I guess my overall question is - having read a lot and tried a lot, I can't seem to get tracking autofocus figured out. Is it the crappy lens? The light? What the best C-AF tracking setting?
