Prime lens or zoom? Both the Nikon Z180-600mm f/5.6-6.3 VR and the Nikon Z600mm f/6.3 VR S are suitable for bird photography. But even if the speed and maximum focal length are the same, there are also significant differences. This video deals with handling, autofocus, price, image stabilizer and, of course, image quality.
