Initial impressions of the Nikon NIKKOR Z 600mm f/4 TC VR S lens from a nature photography perspective by Elbert Jan Achterberg:
The combination of acceptable weight, size and the built in TC of the Z 600 mm F/4 TC were irresistible to me. The lens was ordered on December 2 and received in mid January, so as I’m writing this I’ve had it for about two months. Enough time to get an impression of the optical quality and handling that I’d like to share here. There may be some insights that are useful in deciding if it makes sense to switch from your current horribly expensive exotic to this one. For thorough reviews that include proper evaluation of sharpness look to Steve Perry, Brad Hill or Photographylife. However, if you think you need this or any other review to determine whether you should buy the lens you probably shouldn’t buy it.
Handling
Size comparison F to Z (from left to right: 500mm F4/E, 500mm F/5,6P, Z100-400mm F/4-5,6 and Z 600mm F/4). Note: The lens hood on the 500mm is considerably longer than on the 600mm.
I’m a compulsive tripod user so do not expect info on hand-holding. Walking for longer distances with the lens on a sling (and tripod on a backpack) worked fine for me. The lens is quite big but well-balanced with a Z9. Balance on a tripod with a fluid head was also fine although I will probably replace the foot with a low-profile Arca Swiss foot to bring the center of gravity closer to the tripod head.
It has been said many times but the added value of the integrated TC cannot be overestimated. Being able to instantly change framing is great, especially in situations where there can be an interaction between animals. To be able to get a portrait in one shot and instantly change your field of view for an interaction between animals is priceless in situations like the deer rut which are always hectic with animals constantly interacting and changing distance.
