RMC Tokina 35-105 mm f/ 3.5-4.3 is a manual focus zoom lens with Nikon AI capabilities (meaning the lens has a prong that will meter couple to older Nikon 35mm manual focus SLR cameras). The multi-coated lens is a push-pull type, thus the focal length is changed by pushing or pulling the focusing ring and the lens length is changing at the same time. Its multi-coating minimizes flare and ghosting while producing sharp images. Focusing down to 0.135m allows you to take 1:4 macro scale photos. The 35-105mm zoom lens begins as a wide-angle and extends to a medium telephoto lens, which is great for scenic, portraiture and other applications.
