Nikon Fieldscope ED50 13-30x50 Reviews

Amazing optics in a compact package…

By Bryan
Rated 5 out of 5
Date: 2026-01-28

This Nikon spotting scope is just about half the weight and size of the cheaper equivalent that we've been using for the past 24 years. Resolution is stunning, and the range of magnification seems ideal. Given this performance, the need to reach forward to access the inconveniently placed focusing knob is clearly tolerable.

Great Image; Terrible build quality

I received this in July for the October/November hunting season in Montana. It never left the truck and was not abused in the least. The entire body separated at the seam right behind the eyepiece. It's toast. I was wavering between scope and the Vortex compact spotter, but went with this because Nikon has been great in the past. B&H said I would have to contact Nikon directly because it was over 2 months and wouldn't do an exchange for the Vortex. Nikon has been tough to deal with directly.

question

Are there adapters for digiscoping w/ a Nikon DSLR (D750, perhaps)?
Asked by: Robert
Yes you will need a T Mount for your camera for digiscoping. This is the B&H part number for the T ring for your camera, B&H#KOTMN. When you get the T ring home before you can start digiscoping. You will need to take the lens off your camera and screw the T ring in it's place. The only other thing you will need is an adapter for the telescope you are using. The adapter will depend on the telescope you have. After you get the correct adapter attach it to the telescope and screw the camera onto the adapter. Then start shooting.

Does the Nikon Fieldscope ED50 13-30x50 Spotting Scope (for angled viewing) have a Arca-Swiss style quick-release mounting foot (that fits a Really Right Stuff tripod clamp)?
Asked by: Bryan
The foot on the Nikon scopes is not Arca compatible. So far very few brands make scopes with an Arca compatible foot. You can attach an Arca compatible plate to the foot to use it on your Really Right Stuff tripod.

What is the "padded case" that's listed as being included, please? Is this a box that's padded inside... or a soft pouch for carrying in the field?

The Nikon Fieldscope ED50 comes with a soft padded stay on case. You can use the case to carry the scope and you can leave the case on while using the scope.

question

Which eyepiece and tripod do you recommend for this scope?
Asked by: dianne s.
First ...this is an amazing scope ......superb clarity . We own 2 other scopes and this is the one that goes to the best destinations for birding......even when weight is not a factor .It is so light and compact , that it needs a light and compact tripod ....Gitzo Traveller is what we use , with a ball head . The combo will fit in a medium size daypack for hike to birding sites. The 13-30 eyepiece is fine......we added a lesser power fixed eyepiece ( less than 30 ) wide angle ....for scanning large expanses of marsh or lakes , but carry both for an occasional raptor in a distant tree , or a moose way across a lake .
