Nikon announced two new EDG fieldscopes with VR technology (world’s first).
They can be attached to a DSLR with an adapter - see this guest post for
more info.
Key features:
The world’s first fieldscopes featuring Nikon’s lens-shift type VR (
Vibration Reduction) system (as of October 2011)
It reduces vibrations to approximately 1/8*2 during observation,
providing the equivalent of a shutter speed approximately two stops*2 faster
in digiscoping
Easy VR operation; after turning the VR lock knob, pressing the VR
button once activates the function
VR function turns off automatically after approximately 30 minutes of
turning VR on (Auto power off function)
Readily available AA-size batteries are used
Extra-low dispersion (ED) glass for chromatic aberration compensation
and brighter, clearer viewing
Phase-correction-coated roof prism for high resolution
Dielectric high-reflective multilayer prism coating on roof prism for
the brightest view (straight model only)
All lenses and prisms are multilayer-coated for the brightest images
Waterproof (up to 2 m/6.6 ft. for 10 minutes)*3 and fog free with
nitrogen gas (body/eyepiece joint and body/battery holder joint are water-
resistant*4)
Stylish design
Three tripod mount screw holes provided for flexible mounting; optimum
balance achieved through CAE (Computer Aided Engineering)
Seven eyepieces exclusively for EDG Fieldscopes are optionally available
Built-in sliding hood protects objective lens
