Nikon's flawed dynamic AF modes. D5/D500
#7
  I read the manual basically it says,

 

Dynamic AF, The camera will focus based on information from surrounding focus points if the subject briefly leaves the selected focus point. The number of focus points depends on the mode selected.

 

 It then goes on to say:  Dynamic 153 points.Choose when subjects are moving quickly and are difficult to frame in the viewfinder eg Birds!

 

                                    Briefly in this case means, the time that you chose in the focus lock A3 menu, (0-5)..            0= approx 0.3 sec.....  5= 0.6 sec.

 

 If you select "even" from the "erratic- even"  menu ....that will give you about a 1 second delay.    Which means, if you cannot hold the AF point on the bird for one second the AF will focus on the background, and if you get the AF point back on the bird it will take 1 second to reacquire focus!

 

   Your bird has flown away, no frozen wings here!

 

  In my book that pretty much renders the dynamic mode useless for anything smaller than a large family car.

 

  My guess is that Nikon bring bring out a FW that changes the tittle from:

 

        "Dynamic AF mode"  to  "Dynamic TGV train AF mode"  Tongue
