Nikon decided to do something a little different when launching its bright super-telephoto 400mm for mirrorless — a built-in teleconverter. While teleconverters can be added to any compatible lenses, the process of taking it on and off is time-consuming. With the Nikon Z 400mm f2.8 TC VR S, photographers can switch from 400mm to 560mm in milliseconds, without dismounting the lens to remove the teleconverter. That’s an important distinction for a lens designed for fast subjects like wildlife and sports, when removing the teleconverter could mean the moment is gone.
