Hi everyone,

my lens Nikkor 24-85mm F2.8-4.0 seems to have a sluggish autofocus, especially for far range between infinity and 7ft. The AF is fast if swinging from far to near and vice versa (e.g. when I hold the hand before it and take the hand away in the video) but quite hesitant if focus on different targets at the similar distance. Could you tell by looking at the video below whether it's sluggish with this particular lens or it's symptomatic for the model

Sometimes it has even problem to focus but oscillates between 7 ft and infinity for a while on the same target, in which case I have to swing the camera away then back to get it focused; light condition was OK, not dim lit. The focus issue with slugginess and oscillating causes of course to miss fast action e.g in animal photography, they don't wait for you most of the time
