Thread: is there such a thing as fastest AF ?

  1. #1

    Default is there such a thing as fastest AF ?

    i recalled playing with a few digital cams in comex and found their AF slow to my context and also some ads boasting the fastest AF in it's class etc.

    is there really a fastest AF for digital cams ?

    Those are relative (in it's class) facts, not absolute

    Just remember fast or slow is relative terms. Depend on what standard you compare to.

    As yes, there will always be a 'fastest af' camera in its class.

    Fastest (absolute) AF: Focus on d=x ,t=0 where subject, x, is at distance d, and where t is time.
    The equipment can only bring you so far - the rest of the photographic journey is done by you.

    Learn how to gauge distances with your eyes and you'll have the fastest focussing camera (whatever it is), even in low light.

    I have some cameras that take pics the moment the shutter button is depressed. zero AF time. these generally cost less than $100 But don't believe everything a manufacturer boasts. even if a camera is "fastest in its class" now, it'll be overtaken soon. and generally, manufacturers don't state what "class" the camera belongs to. it's bst to try out and see if you like the AF performance.

    maybe I misunderstood your question. Do you need to rephrase so that you get meaningful answer?
