Nikon’s answer for extending your lens’s focal length by 1.4x, the TC-14E II provides a great, inexpensive way to essentially give yourself another set of lenses. Great for wildlife photography, using this teleconverter you’ll lose one stop of light from the lens you’re adapting. Maintains autofocus, aperture control, and metering.
