Sorry - but this really "Gets my Goat".

People keep posting about focusing speed - this camera is faster than that camera - with this lens - with that lens - with this turned on - with that turned off!!!!!

When you take a picture, you think about the finished scene / subject and how you want the photo to look, you compose the scene, check your settings, check 100 other things then - focus. The focusing is the least time consuming part of the process and in my view, unless you are shooting sport, moving wildlife, fast moving subjects etc. the time it takes is not critical.

But isn't that precisely what fast-focusing capabilities are about? Fast moving subjects!

Anyway, you are obviously proficient enough in photography to realize yourself when fast AF is desirable, or needed in fact, and when not.

Basically, the chances to 'miss shots' increase when scenes change faster than one can adjust shooting parameters. Many of the '100 other things' you've mentioned can be dialed in before ever putting the camera up to one's eye. Often, the only thing that's left is to focus and push the shutter release. It is under these circumstances that fast focusing becomes the limiting factor.

Others have listed enough important types of photography where fast focusing is crucial. If one doesn't engage in such photography, prefers to work with huge depths of field, or waits until something interesting moves into the area one has pre-focused on, then it's all fine. But others may want to be able to react to scene changes in real time.

If anyone can provide an image where a shot was ruined due to focusing speed being a nano second slower than expected or can tell a story where they missed a once in a lifetime shot because of "slow" focusing - I would like to hear it.

Awaiting the flood.

I can't even begin to count the instances of half-closed eyes and half-turned heads of people that surely everyone has encountered. You too.
