What current model compares the the discontinued Vortex Fury?

Question: My wife has a pair of Vortex Fury 8X42. I really like them and was going to buy the same but note that they are discontinued. What is the equivalent? I like the 5 foot close focus possibility.Also, I prefer eyecups that twist up and down like the Fury's did.




Dear Gary,
Thanks so much for your inquiry. It’s true that the Fury is discontinued, and has been for a few years. I’d say the current equivalent would be between these two models:

Vortex Diamondback 8x42 Binocular ($219.99) Close focus 4.5’

Eagle Optics Ranger ED 8x42 Binocular ($329.99) close focus 5.2’

The image through the Ranger will be noticeably brighter and sharper than the Diamondback, but physically, the Diamondback looks more like the Fury did, and is a couple ounces heavier than the Ranger.  I suppose the decision will rest with your budget, though. Both have no-fault warranties, and both have twist-up eyecups.

If you click on the “media” tab on the product page, we have a 1-minute video showing the features of each of the binoculars, including the eyecup mechanism. Click on the above links to view each of the binoculars and their videos.

If I may be of further assistance, please let me know.

Yours truly,

Want to use the Sony Alpha 6000 for digiscoping


I have a Swarovski 65mm ATS spotting scope. I am wanting to use the Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS for pictures. Do you know if it is compatible with a Sony Alpha 6000 mirrorless camera?

Jeff M.


Hi Jeff,
Thanks for your inquiry. Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS works well with most small-bodied point-and-shoot cameras with a low optical zoom (4x or less). So I would think it’d work with the Sony Alpha 6000. Mirrorless cameras often work with either of the two Swarovski adapters.  With the Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS , you would also need the Swarovski T2 Adapter Ring (Sony) plus an E mount T ring which we don’t carry, but you could find online or at a camera store.

Our 30-day return policy enables you a generous amount of time to try either of the adapters.

If you have any questions, don’t hesitate to ask.

All the best,

Can the Vanguard Endeavor binocular be mounted to a tripod?

Does the  have a tripod mount?

Thank you,


Dear George,
Yes, the Endeavor has a 1/4"x 20 threaded hole in the front of the hinge.  To mount the binocular to a tripod, you would need the Vortex Binocular Tripod Adapter or similar adapter.

All the best,

Needing upgrade advice

I am looking for a good piece of glass  for birding, preferably 10x42.  I have been in the field as an observer for ten years and have used both Nikon and Vortex.  

I think keeping it under $500 is a good idea, as we don’t tend to make too much money in the environmental education field, but I would be willing to spend more if it’s a deal I just can’t say no to.
I would be very happy with the EO Ranger ED, but I have been in the game so long that I would appreciate a significant upgrade from my Monarchs.  So, I am willing to spend money on a solid piece of glass, but I don’t have much.

Anything EO is willing to do is very appreciated.

Enjoy the long summer days,

Joshua T.


Hi Joshua,

The challenge is finding a binocular that represents a “significant upgrade” from the Nikon Monarch around $500.00. Do you know which generation of Nikon Monarch? Which Vortex binocular have you used? 

Truth be told, some of our staff see little difference between the New Ranger ED 10x42 ($339.99) compared with the Vortex Viper HD 10x42 ($599.99). Depending on the Nikon Monarch model you have, I’m not sure either of these binoculars would represent a “significant upgrade.” 

On the other hand, something like the MeoptaMeoPro HD 10x42 ($899.99) would, in my mind, represent such an upgrade. But then the question becomes are you willing to pay that much for what I define as the upgrade I think you’re looking for? Another $200 or $300 doesn’t really buy the end-user much in terms of optical performance, but this is a somewhat subjective position based on my experience in looking at optics every day. 

I might ask how much of a “wow” factor are you looking for, but that’s also difficult to ascertain via words. Having said all of that, the New Ranger ED is an excellent choice.

Digiscoping adapter questions for my Vortex Razor scope

I purchased the Vortex Razor HD 16-48x65 Angled Spotting Scope last year. I am interested in purchasing an attachment for my  to allow me to digiscope with it. 

On your web site it appeared that you had an adapter that was suitable for this camera.  I wanted to check with you before I ordered the adapter. 

Also, I have also read  that there is a digiscoping adapter for iPhones.  I have iPhone 6 -- do you sell these adapters?  Do you know that they can provide good pictures?




Dear Jeri,
Thanks so much for your inquiry.

For digiscoping, a point-and-shoot camera needs to have an optical zoom of 4x or less. While I'm not familiar with your Canon Powershot, I looked its specs up online, and it has an optical zoom of 30x. While it might be a fine camera, it will not work for digiscoping, unfortunately.

The iPhone 6 will take amazing photos! It is great for digiscoping. You have two choices for iPhone 6 adapters that I am aware of. First is the Kowa TSN IP6 iPhone 6 Digiscoping Bracket which will fit your Razor.  The second is to go to Phoneskope also makes an iPhone 6 adapter that will fit the Razor scope.

If you have any other questions, please don't hesitate to ask.

All the best,

What differences will I see in a 8x42 and an 8x50 binocular?

If I'm considering a 8x42 binocular and an 8x50, what differences would I be seeing between the two sizes in terms of optical quality?


Jim K.


Hi Jim,

Thank you for writing and for your interest in Eagle Optics!

Imagine you have two binoculars with the exact same glass quality and optical coatings, but one is an 8x42 and the other is an 8x50. Let’s say your pupillary opening just happens to be 3.5 mm in the particular lighting situation you’re in. As such, you will not be utilizing the full exit pupil of either binocular (5.25 mm & 6.25 mm respectively). 

At first it might seem that there would be no difference in image quality between these two binoculars, but that would be an error. Not only does aperture increase brightness (when your pupillary opening can receive it), but it also improves resolution regardless of pupillary diameter. Thus, the 8x50 in this example will render slightly more detail because the 3.5mm exit pupil you are taking into your eye is comprised of more photons of light: resolution is a function of aperture size.

Please let me know if there is anything else I can do for you.

Questions about the Kowa TSN IP4S iPhone 4/4S Digiscoping Bracket


So is this only the frame or it will come with the scope ring too?




Dear Miran,
Thanks for your inquiry.

The Kowa TSN IP4S iPhone 4/4S Digiscoping Bracket comes with the bracket and two rings. One ring is larger to fit a scope eyepiece and the smaller one fits some binoculars. 

Under the description on the website, it gives the measurements of each of the rings. If you click on the “Media” tab on the product page, you’ll see a short video which shows the product, how it works, and what is included. You can view the video here:

If you need help figuring out if it will fit your scope's eyepiece, just give us a call.

All the best,

Which binocular for my 8-year-old birder?

Good Evening,
My daughter has recently become a member of Illinois Young Birders and went on her first field trip a few weeks ago.  She was  lucky enough to be able to use the group's Eagle Optics binoculars, and we're interested in purchasing a pair of our own, as my daughter really needs to practice how to use them.  

She struggles with locating the birds with binoculars, so I want to work with her, as I know they are so valuable when birding and will make her experiences so much better.
Can you recommend which type of your line would be best for her?  Again, she's 8 and has a difficult time seeing a bird in the field then locating it with a binocular, as well as focusing.

Thank you!
Christine T.


Hi Christine,
Thanks so much for your inquiry.

For a young person, the most important things to look for in a binocular are low magnification (for wide field of view and ease of steadiness), and a lightweight profile.

The Eagle Optics Kingbird 6.5x32 Binocular fits the bill quite nicely.  Its porro prism design also enables the eyepieces to come closer together for smaller faces. Another must.

We sell many of this model to youth groups and education situations where young people are involved. It’s a great choice—and has an unconditional, lifetime warranty.

Though the Kingbird also comes in an 8.5x magnification, the 6.5x is best for younger people like your daughter, because it has a wider field of view (easier to find birds in the field) and it is easier to hold steady. I wouldn’t do the 8.5 for her age and ability.

If we may be of further assistance, don’t hesitate to call the store at 800-289-1132.

All the best,

Is there a UV filter made for the Vortex Razor HD scope?

I want to order the  + couple other items including a UV filter for this scope. I cannot find any information on the thread size, are UV filters available? If so what size do I need, please?




Dear Stephen,
The  will typically not accept filters, nor is there a UV filter made for it. There are threads visible by the objective lens, but these are cosmetic--merely a design feature.
