I have now purchased two pairs of Vortext Diamondback 8x42 binoculars. The first were for me, the next for my undergraduate research students to use during their field research this summer. The optics are clear and crisp, focusing is not super fast like some binoculars, but the fine focus ability is fantastic and really makes the birds pop into focus. The objective lens covers can slip off when working through brushy cover, but that's minor. I would highly recommend these binoculars to any level of birder.

I bought these to use as a "house" binocular. We have several pair of good binos in the house incl West Germany Zeiss 10x40 and Nikon Monarch. These binos are really good and fantastic for the price. I'd have no issue at all using these as my only binoculars. They are very bright and clear with generous eye relief (I wear glasses). They are ergonomically nice, too, and fit the hand comfortably.
Spence from Missouri
Went to Peru birdwatching with my Vortex Diamondbacks and a pair of Vipers. At the end of the trip our jungle guide was so impressed with the Diamondbacks he made me an offer to buy so I sold and I'm back to buy another pair.The guide looks at birds and other wildlife day in and day out and his impression with the Diamondbacks speaks volumes.
Clarity, value, and excellent price
Dominick from Elgin, Texas
On recommendation from a professional birder, I purchased the Vortex Diamondback as a Christmas gift for my fiance. We had been using my 10-year old Nikon 8X42 binocular which were good, but image clarity was not at a level good enough to accurately identify birds at more than 6- or 700 feet. We compared our new Diamondback with the my Nikon and were blown away with the crisp clarity of images at far greater distances, even on cloudy days. Light weight, easy focus and facial adjustment all add up to exceptional quality, function, and fit at an exceptional price. Could not beat the value for the price tag.

I have been wanting to upgrade my binoculars for some time now.And got some help on xmas!I have had steiner safari 8x22's for years now and like the compact size for bowhunting. But they lack big time in low light and clarity. So I did some research and landed on the diamondbacks. Wow what a up grade. I know its not comparing apples to apples. But its still good to see a u.s based company make a great product with a really great warranty. Its good to know you don't have to spend a grand or more to get great quality that the company stands behind.
Excellent Value for All The Features
Glenn from Pacifica, CA
So were these Diamondback possibly an upgrade to an excellent pair of Eagle Optics Denali binoculars? Yes! The Denali's are certainly moderately less expensive and a terrific value on their own. So I wondered for a year if the Diamondbacks were worth the difference. This year I made the jump (wondering all the time if I'd notice any real differences) and am very glad I did.
So to really compare the low light differences, I compared these at night, looking at stars, clouds, distant city lights, and the halo around the moon. These Diamondbacks are noticeably better in low light (e.g. clearer faint clouds), so either the glass and/or coatings are better. I also noticed in interior lighting that their color rendition is cleaner (less yellowish) than the Denali's.
The very close focus (4.5 ft. vs. 7 on the Denali's) and the really wide field of view (420 vs 408) make this an excellent value and a true upgrade. Love the rounded eye cups but, as others have noted, Vortex really needs to create tighter lens covers for both ends.

Vortex Diamondback binoculars
Barbara Cole from Orlando Fl
Just ordered these as a birthday gift to myself. Excellent binoculars for the price. Image is very bright, clear and sharp. The focus knob is a little stiff in turning but I have arthritis so that probably doesn't help much. Very satisfied and highly recommend them!
New binocs for my son
Mary Belle Royer from Cedar City, Utah
I purchased the Vortex Diamondback 8 x 42 for my 18 year old son. He is doing a lot of outdoor activities and needed a better, more reliable pair of binoculars. He is very happy with his new binocs. I have borrowed them and may purchase a pair for myself soon. I would recommend this pair of binoculars for a non-professional naturalist.
Great for Birding
Dave from Illinois, Chicago Suburbs
My neighbor, who is an environmental engineer, recommended Eagle and Vortex.
He is working with my daughter (12) and I to get into birding.
Great upgrade to what we were using. Beautiful clarity and field of vision.
Helps to find the little birds hidden in the trees.
We have identified 60 birds since March for her Life List.
Eagle was great to work with.
We're thinking of a second pair so we won't have to share.
ps: Check out Peterson's Bird app on the iStore. Best $2.99 I have ever spent.
Mike Martin from Mt. Carroll, IL
I'm an amateur astronomer and only recently a birder. I'm recently retired and wanted a nice (not too expensive) pair of binoculars for birding. These Vortex Diamondbacks are impressive for the money. The clarity of the optics was amazing. The padded neckstrap and zippered clamshell case were nice touches as well. Unfortunately the manual succumbed to my standard poodle puppy. I hope I can get another manual from Eagle Optics.
Len from Cranbrook, British Columbia
I bought the 8x42 Diamondback binoculars last year on the advice of a friend and have not looked back! I use them primarily for hunting and they are awesome to look through for extended periods of time as your are spotting for animals. They work great for those low light conditions at dawn and dusk.
Bernard P. Giroux from S. Dartmouth, MA
These binoculars deliver more than expected in terms of clarity, ease of use, field of vision, field weight and other factors. For the money, these glasses are exceptional. I am now thinking about a pair for myself, since this first pair were a gift.
Outstanding value for the price!
Kevin Cross from New York
These are high quality binoculars and are ideal for eyeglass wearers. I used them while hiking & kayaking in the Adirondack Mts and their performance was superb. Images are very steady at distance and bright (even in subdued light). The neck strap is very comfortable. Minor problems; the tethered lens covers can detach easily if you're not careful and I watched one sink to the bottom of the lake. Luckily, replacements are readily available from Eagle Optics. Also the diopter wheel is stiff to operate. Overall I am very happy with my purchase.
Michael Proseus from Upstate NY
I was looking for a quality roof prism bino for general nature viewing. I considered the Nikon Monarch and the Leupold Cascades before talking to one of Eagle's product advisors. He suggested the Vortex Diamondback, which costs 25%-30% less. I bought a pair. They are better than the Monarchs and the Cascades, in my opinion. They're very well made, smooth focusing, bright, clear, sharp throughout the entire field, and have great color rendition thanks to the phase correction. They're everything I was looking for, and at an unbeatable price. Eagle's customer service is top-notch, and their prices are great as well!
Crystal Clear - Easy Grip
David Carrera4 from Canton, MI
I decided to upgrade from poro-prism binos to the Diamondbacks, what a smart move. These low priced roof prism binos are crystal clear and bright. Compared to my Nikon Naturalist binos, these are an order of magnitude better. Maybe the Razor is sharper or brighter, but I cannot see how. They have a nice wide field of view which was important to me. The twist down eye cups are firm with a detent in the middle position. I can use these with or without my glasses. The diopter adjust is nicely done and holds its position. There are grippy fingers molded into the rubbor armor that feel nice to the touch - these binos are well balanced and easy to grip and don't feel too heavy. The thumbwheel requires more than one rev to focus, but feels great and steady. The neck strap has a wide comfy area for the back of the neck. The lens caps can stay with the bino - which is a nice feature. For the price, these have to be at the top of their class - maybe surpassing many many higher priced products.
