Autofocus Speed for fz serie (1 Viewer)

Hi All,

Just went though the great thread about fz100. Lots of discussion about autofocus speed. I am myself the happy owner of a fz 28.

Is there any way to quantify the autofocus speed of all those great cameras? I understand that the main improvement of fz28 over fz18, and fz45 over fz28 was autofocus speed (in my opinion, the most important detail to improve for those cameras), but I was never able to find any detail about autofocus speed.

There would be if you have someone with a stopwatch standing next to you: focus (using half press) close (say 1 m), point in the direction of a distant object (say 10m) say now when you start the half press and again when the focus seems ok to you. Repeat in both directions several times and take an average. For birding, I guess full zoom would be appropriate, other photographers would like to see repeats at other focal length.

Now, one important aspect is to do that experiment in different lights: full strong sun would probably be the fastest, and even a dSLR falls off when the light dims.

To eliminate user error/variation, it would be best if you did the measurements all on the same day with all different cameras under the same light conditions.
