The 82mm Nikon Fieldscope III ED provides the best low light/high power images available from spotting scope in its aperture range. Its 82mm objective lens gathers over 59% more light than similarly-priced (but smaller aperture) competitive 65mm scopes (and over 13% more than higher-priced competitive 77mm scopes). This results in the ability to make positive identifications in low light or at very long distances when those smaller scopes have trouble even seeing the bird.

Its 82mm aperture also produces higher resolution than smaller aperture scopes, so there is simply more subtle detail to be seen in the scope’s brighter images, no matter how bright or overcast the sky might be. For serious long distance observing, when you need to see all the small detail there is to see in order to make an identification; for serious low light observing, when you need as much image brightness as your scope can possibly produce to even see the bird at all – the Nikon 82mm Fieldscope gives you all the light-gathering and exceptional optical resolution you could hope for. This is a big spotting scope that lives up to the fabled Nikon name and reputation.

Optical features of this scope . . .

• ED glass: The extra-low dispersion ED glass element in the Nikon’s 82mm doublet objective lens combines high light transmission with very low chromatic aberration. This gives markedly reduced color fringing at the edges of the field when compared with conventional crown and flint glass optics, plus excellent color fidelity and saturation across the field.

• Fully multicoated: The optics are fully multicoated with Nikon’s proprietary high transmission antireflection coatings for an excellent light transmission that complements the excellent color fidelity of the ED objective lens.

• Zoom eyepiece: The standard equipment 25-75x multicoated zoom eyepiece has a rubber-rimmed eyecup that twists up, shielding the eye from ambient light for better contrast when observing with the unaided eye. The eyecup twists back down to provide greater eye relief for eyeglass use. The eyepiece threads securely into place and can be changed in seconds. An optical glass window at the rear of the Fieldscope’s body, just inside the eyepiece port, seals the porro prism optics against moisture and dust which might eventually cause damage. At 25x the field of view is 84’ across at 1000 yards, dropping to a 42’ field at 75x.

• Good eye relief: The eye relief is specified as 14.1mm at 25x. While this is technically correct, the actual usable eye relief will typically measure a mm or two less due to the recessing of the eyepiece lens to protect it from being scratched accidentally when the eyecup is in the down position for eyeglass use. A somewhat shorter eye relief than specified is typical of all spotting scopes. There will be some vignetting of the field for eyeglass wearers.

• Other eyepieces available: The supplied premium quality 25-75x zoom eyepiece is so exceptionally sharp and high in contrast that many birders see no reason to buy individual single magnification eyepieces. For those who wear eyeglasses, however, or for those who want wider fields of view than any zoom eyepiece can provide, Nikon has a wide range of optional eyepieces available. There is a wide field 25x eyepiece with a 126’ field at 1000 yards and 15.2mm of eye relief. There are also long eye relief 38x, 50x, and 75x fixed magnification wide angle models with an eyeglass-friendly 17mm or better eye relief. There are also 30x, 50x, and 75x eyepieces designed for digiscoping.

• Good close focusing: The scope close focuses down to a good 16.4’, making it usable for viewing backyard feeders, although the field is only 5.5" wide at this short a distance. Through the scope, looking at a bird at this distance at 25x would effectively be the same as looking with your unaided eye from only about 8" away.

• Fully waterproof: The rugged Fieldscope’s die-cast body is O-ring sealed and dry nitrogen purged to be totally waterproof and fogproof in all weather and temperature conditions. This allows the scope to survive sudden showers as well as full monsoon conditions, and to resist internal fogging, no matter how cold the air temperature or how high the humidity. A rubber-armored self-storing lens shade slides out from the front of the body to improve visual and photographic contrast. Light rubber armoring around the prism housing helps protect the optics from unexpected bumps and thumps.

• Handy focusing collar: The Nikon Fieldscope uses a wide knurled rubber focusing collar around the barrel that can be operated with either hand, even while wearing gloves. The focus moves from the horizon to a good 16.4’ in a mere three-quarters of a turn of the collar. Focusing is smooth, although it can get a little stiff during long sub-freezing observing sessions.

• Straight-through viewing: The Fieldscope’s straight-through design is generally better for quickly locating birds in the field than a 45° viewing angle model. With a straight-through scope, you can sight over the barrel to center in on the bird before trying a high power eyepiece view that often has a confusingly narrow field. It is difficult to sight over a 45° viewing barrel, as the prism housing and eyepiece can block the view. On the other hand, a 45° viewing angle is generally more comfortable than a straight-through scope for watching treetop activity or for extended observing from a blind or back porch. You won’t get a crick in your neck from crouching over to look through the scope as you often have to with a straight-through model on a too-short tripod. A 45° model is also more convenient for couples of varying heights who must share a single scope, as there’s little need to constantly raise and lower the tripod to a comfortable height for each observer. The Nikon #N82EAZ is such a 45° viewing model, should that style be more convenient.

• Photo tripod mounting: The 82mm Fieldscope mounts on any photo tripod having a standard 1/4"-20 thread mounting bolt. It converts to a Nikon-quality 1000mm f/12.2 telephoto lens when used with optional four-element photo adapter #1317 (for use with Nikon cameras only, with no T-ring needed).

• Supplied accessories: Protective dust covers are provided for both the objective lens and the eyepiece. A soft water-resistant carrying case of Cordura-type nylon (with adjustable length shoulder strap) is standard equipment. The case is the stay-on type that allows you to mount the scope on a tripod with the case still on the scope. Fold-back flaps give you full access to all controls so you can use the scope while it is still in its case. A separate soft zippered carrying case for one or two additional eyepieces that attaches to the shoulder strap is also standard equipment.

• 25-year warranty: In addition to the 25-year limited Nikon USA warranty, the 82mm Fieldscope is also covered by Nikon’s unique no-fault warranty. If anything happens to the Fieldscope that’s not covered by Nikon’s normal 25-year warranty, it costs you only $10 and return shipping and handling to get it fixed or replaced! Whether you drop the Fieldscope out of a canoe, drive off with it on the roof of your car, or loan it to a clumsy friend who uses it to drive tent pegs, there’s no need to worry. If you can send back the pieces, you’re covered by Nikon’s no-fault warranty.
