This Nikon F-mount SP 70-200mm f/2.8 Di VC USD G2 Lens from Tamron is characterized by its bright f/2.8 constant maximum aperture, as well as sophisticated optical and physical designs. Complementing the optical assets, this 70-200mm f/2.8 also features an advanced Vibration Compensation (VC) system that compensates for up to five stops of camera shake for sharper handheld shooting. A ring-type Ultrasonic Silent Drive autofocus motor is also featured for responsive and accurate performance, and also affords full-time manual focus override for fine-tuned control. Spanning a useful range of telephoto focal lengths, this lens is designed for FX-format Nikon F-mount DSLRs, however can also be used with DX models where it will provide a 105-300mm equivalent focal length range. One XLD (extra-low dispersion) and five LD (low dispersion) elements are featured in the optical design to noticeably limit color fringing and chromatic aberrations for improved clarity, color fidelity, and apparent sharpness. A ring-type USD autofocus motor delivers quick and precise focusing performance to suit working with moving subjects. This motor also affords full-time manual focus control, and it is possible to focus on subjects as close as 3.1' away. A removable rotating tripod collar features an Arca-type compatible foot and benefits working with the lens atop a tripod or monopod. An electromagnetic diaphragm is used for more precise and consistent exposure control, especially when shooting at high continuous shooting rates.
