Photos taken with the Nikon AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR lens
This series of photos displays the ability of the Nikon 180-400 lens to zoom and track a subject all the way from 550mm down to 250mm !!! All 48 of these photos were taken in exactly 5 seconds using the Nikon D850 camera (at 9 fps with the battery grip attached)
Most of these photos are in relatively good focus - but the reason some are not is that this puppy is only 3 lbs in size, and autofocus tracking a SMALL darkly colored dog is one of the most difficult things a camera can do (and also the teleconverter was engaged in this series of shots - which probably yields slightly poorer autofocus tracking than without the TC used on this lens.) (It's way easier for a camera to track autofocus on a race car coming towards you at 200 mph than it is to track a small black dog.)
