Nikon Fieldscope EDG Fieldscope 85 VR Straight
The vibration reduction algorithm, based on Nikon's sophisticated VR mechanism used in NIKKOR VR lenses, has been optimized for these scopes and compensates external vibrations caused by wind and operations such as focusing, panning and tilting.
The VR function makes composition easy by reducing vibrations to approximately 1/8 of image blur caused by vibrations during normal observation.
This also enhances focusing accuracy even when manual focus is used during super-telephoto digiscoping. The system provides an effective equivalent to a shutter speed approximately two stops faster and is especially effective when digiscoping in bad conditions such as windy weather.
