Nikon has raised the bar in Spotting Scope technology. It has introduced the first-ever spotters with built-in Vibration Reduction. This may be a significant breakthrough. Image stabilization has revolutionized hand-held photography, and it could definitely improve the practical functioning of spotting scopes. If you have ever used a big, heavy spotting scope, you know that it is easy to induce vibration and shaking — merely with a heavy hand on the focus knob. And when the wind blows, a big scope acts like a sail, so it can wobble and vibrate in gusts. Just a small amount of shake or vibration can make it difficult to see your target, slowing down your target acquisition time considerably.
Nikon’s new 85mm EDG Fieldscopes are the first spotting scopes on the planet with lens-adjusting image stabilization. The EDGs employ a lens-shift type VR (Vibration Reduction) system that counters vibration and shaking. According to Nikon, the EDG VR system greatly reduces external vibrations caused by wind and the operational vibrations occurring during focusing, panning and tilting. Nikon claims its VR system reduces vibration to 1/8th the level of a conventional spotting scope.
HOW IT WORKS — This system uses two independent Angular Velocity sensors to detect pitching (vertical movement) and yawing (horizontal movement). Both sensors then detect diagonal movements. Upon the detection of movement, the sensors provide instructions to the two Voice Coil Motors (VCM) that command and control the Vibration Reduction-optical system to eliminate the shake or blurring. These sensors can detect movement every 1/1000 second. The system can effectively reduce vibrations by roughly 88% (compared to a conventional spotting scope), providing the equivalent of a shutter speed approximately two stops faster.
So how much does this new VR technology cost? Hold on to your hat — MSRP for the 85mm EDG VRs (either body style) is a shocking $5,499.95! At least that includes eyepiece and protective case. We can only hope that, as this technology matures, it will be implemented at much lower cost. Consider that $200.00 point-and-shoot cameras now offer image stabilization. Given time, we can expect the vibration reduction systems to go down in price, and to become commonplace in premium spotting scopes.
Available in a straight or angled body, the all-new EDG VR Fieldscopes come standard with a 20-60x Zoom Eyepiece, ED (Low-Dispersion) glass, and multi-coated lenses. The 85mm EDGs feature a five-meter close focus distance and waterproof, fogproof construction. Weighing in at just over 84 ounces (w/o batteries), the straight-body EDG is 14.9″ long, while the angled version is 15.7″ long. Nikon’s VR system takes four AA batteries which provide roughly 17 hours of battery life with alkaline batteries and up to 32 hours with lithium. While the VR function can be manually activated, an auto power-off function helps conserve battery life. Seven optional EDG eyepieces are available. Three tripod mount screw holes permit flexible mounting.
