Abbreviation: VR = "Vibration Reduction" (Nikon)

The abbreviation VR means "Vibration Reduction" and is seen on Nikon products.

Explanation from Nikon

This innovative VR system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed three stops (eight times) faster.* It allows handheld shooting at dusk, at night, and even in poorly lit interiors. The lens’ VR system also detects automatically when the photographer pans — no special mode is required. * As determined by Nikon performance tests.
