Originally posted by MightyMike Then don't worry about it, why would you be concerned about AF if its not something you care to use often? Those who use AF is extreme situations certainly should be interested to know if it can be effective in such situations. When it comes to static objects and low light the vast majority of cameras are perfectly fine so one doesn't care to test those metrics. That said if the AF can handle the extremes its highly likely it can handle the other metrics.
I use AF all the time. Constantly in fact. That said you bring up an interesting point. Knowing what your camera is designed for is important. Knowing where the limitations are is important. That is actually valuable information. It is not however the be all and end all of photography. When AF stops working, go to plan B.
Considering that for most relatively slow moving and especially static objects the AF in a point and shoot will work just fine. Considering what the photographer intends to do makes the AF discussion more or less important depending on the answer. That would apply equally as much to camera bodies too. A 3 fps clunker might be the cat's meow for everything---except Formula One.
It boils down to the right tool for the right job. Even the 645z or even some expensive Hassleblad, however awesome those cameras are, they are not intended to be high speed.
Really at the end of the day, like I said, AF tests are often only used to measure a single metric or even a single type of photography. Comparing a 12fps with F16 Strike Eagle AF tracking modes to a Hassleblad medium format is comparing apples to oranges... If we measure strictly by which one has the best 'hummingbird in flight' tracking ability, then by all means 'Hassleblad's system sucks too'.
Yet, people persist in proclaiming what is or isn't the 'number one' or 'best' AF. Again it begs the question, 'the best AF for what'?

I'm far from a professional. I've never been paid a nickel for a picture. I'm just a layman like 95% of the people here. That said professional or not, layman or not, the object is to take and capture photos. I am kind of in a 'no excuses' mood right now so the whole "I didn't get the shot because my AF..." doesn't fly.
Amateur or professional alike, the question remains. Do you want good pictures or not? That's a yes or no question. If the answer is yes, and this is not at all detracting from good AF system at all, but if one wants good pictures they need to know how to get them in all kinds of situations, including not having AF at all.
