Background and Identification
The Nikon 70-200mm f/2.8 VR is an all-purpose professional telescoping-zoom lens that is designed for news, sports, indoor sports, and theatre photography. It is not compatible with manual-focus film cameras. The ‘VR’ in the lens’ name stands for Vibration Reduction. The Nikon 70-200mm VR was Nikon’s top professional zoom lens for news and sports photographers beginning with its introduction in 2003 through 2009. In fall 2009, the Nikon 70-200mm VR was replaced by the 700-200mm VR II lens.
The Nikon 70-200mm VR is a full-frame FX lens that is compatible with FX and DX digital single-lens reflex (SLR) cameras.
Nikon calls this lens the Nikon AF-S VR Zoom-Nikkor ED 70-200mm f/2.8G IF. The ‘AF-S’ refers to the lens’ Silent Wave Autofocus Motor. ‘G’ stands for gelded, meaning the lens’ aperture ring was omitted to save cost, so the lens will not work on manual-focus cameras. The ‘ED’ stands for Extra-low Dispersion glass, which is included for sharper pictures. The ‘IF’ stands for Internal Focusing, which means that no part of the lens moves externally as the user zooms or focuses. The Nikon 70-200mm VR lens includes a gold-colored plaque on the top of the lens that includes the name “Nikon ED” and the specifications “AF-S VR-NIKKOR 70-200mm 1:2.8G” underneath.
