Power in your pack

This lightweight yet powerful spotting scope offers everything you'd expect from Nikon: superb optical elements, impeccable build quality, and logical, ergonomic design. It may be easy to transport, but it features almost all of the distinguishing characteristics that make its bigger brethren so popular and respected.

The angled eyepiece makes it easy to adjust this scope so it's quickly useable for people of differing heights — something that will come in handy while peeping out unusual fauna on the trail, or stargazing in the backyard.

Impeccable optics mean impeccable images

A variable-focal-length 13-30X eyepiece receives light from a capable 50mm objective lens, so even when you're zoomed in at 30X, you'll notice that low light isn't quite the challenge you may have feared. Specially coated internal prisms and extra-low-dispersion glass elements have been engineered to deliver high-contrast, color-accurate images down the light path. The scope has been internally nitrogen-purged and O-ring sealed for fog-proof and waterproof performance. Plus, an included sliding sunshade protects the front objective from being struck by dust or rain when you're trying to identify that boat offshore.

    Overview: The Nikon Fieldscope ED50-A includes the 13-30x Zoom Eyepiece MC, which screws into the scope body. The fieldscope comes with a soft, padded neoprene storage case and a shoulder strap. The ED50-A can be mounted to a tripod with a standard 1/4" tripod thread.

    Water-Resistant: The ED50-A fieldscope is waterproof, and will not suffer damage to the internal optics if dropped or submerged in water up to a depth of 1 meter for up to 5 minutes. It is nitrogen-filled and O-ring sealed to protect the lenses and prism from condensation and mold.

These high-grade optics are fully coated in multiple layers of anti-reflective compounds for bright resolution and brilliant color.

    Product reviews from the Crutchfield Labs

    A nice, lightweight optic for spotting birds and other wildlife

    Written by Zak Billmeier, Staff Writer - Creative, on 8/28/2013 10:18:00 AM

    Nikon calls this model the "ED50A."

    This is the first fieldscope I've tried, and I must say, I came away impressed. If you're into spotting birds or other fauna out in the wild, this is a valuable tool.

    First and foremost, it gets you really close, and gives you a bright, sharp picture of the skittish creature you're watching. I was struck at the detail I saw on a dragonfly, for instance — it was perched on a reed about 30 feet away and I was able to fill the viewfinder with it and really study it.

    Then I brought the fieldscope home and set it up in my dining room, pointed directly at my bird feeder. Every feather, every cracked seed was easy to see. I started seeing identifying marks on return customers and even began naming them.

    The ED50A has a 1/4" tripod thread on the bottom so you can stabilize it (highly recommended). In the field, perhaps you could get by with a monopod, but you definitely want one or the other. The angled viewfinder is nice so you don't have to raise your tripod to unstable heights or stoop down to look through it.
