Vortex Viper 8x28 Bins - 03/26/2016

by Joan C. from Indio California

These smaller Vipers are just what I needed - very light for traveling and the viewing is just as good as my larger Rangers. Great for birding closeups

Vortex Viper Binos - 02/23/2016

by John from Michigan

Excellent binos, get you some.

Pleased with the Vortex Viper Compacts - 02/16/2016

by Ron R. from Minnesota

My wife and I are birders who take binoculars almost everywhere we go, including kayaking, backpacking, and cross-country skiing, so we’ve spent a lot of time using compact binoculars. We both love our larger Vortex Viper models (8x42 & 10x42) so when I needed a new pair of compacts I looked at these 8x28 Vipers first. These are the third model of good quality compacts that I have owned over the last 40 years (plus about a half-dozen cheapo compacts), and I believe these are the nicest. I’ve had them a little less than a month, but I use them daily. I strongly agree with other reviewers regarding their great optics, very light weight, more than adequate eye relief (I wear eyeglasses), and good close focus (I measured it at 7 to 7.5 feet). In addition, I find them very easy to use with one hand, with my index finger naturally falling on the large focus knob. I live in Minnesota, so I tested them in cold conditions. After acclimating them to about minus 5 degrees F the focus knob still turned easily, unlike another quality brand compact I have owned. The focus knob is large enough to operate easily while wearing moderately heavy gloves, too. Finally, the center hinge is tight enough to hold whatever angle you put them at, unlike many of the dual-hinge compacts that are hard to get into, and to keep at, the optimal configuration for a user’s eyes. The only complaint I have is that the Vipers don’t fold up as small as dual-hinge models, but given the inherent drawbacks of the dual-hinge design, I’m happy to live with the slightly bulkier Viper 8x25 model. Mine came with individual objective lens caps, a rain-guard for the eyepieces, neck strap, and soft case. Now my wife is considering buying a pair to replace her still-functional compacts, too.

Vortex Viper 8x28 Bins, small but pack a punch - 09/11/2015

by Will from Northern New Mexico

These Binos were as advertized size and weight-wise. Other reviews have said 'they don't fit in your pocket', they may not fit in a conventional pant pocket but they'd fit into a vest pocket or a cargo pant very easily - besides, Binoculars belong on your neck not your pocket! I got these for my partner so she could have a small travel pair that wouldn't take up too much room in a bag/day pack while traveling. I was very impressed with the glass quality and clarity. True color. The field of vision is obviously small, but that was expected. I bird with a pair of Eagle Optic Ranger 8x42s, but I'm considering a pair of these in the future for kayaking/traveling. Nice Bins, I'd recommend them to travel/casual birders who need a packable pair of binoculars.

Great optics - 08/21/2015

by James from Mpls., MN

I was looking for a small, easy to take along pair of binoculars for hiking and general nature use. I have larger and heavier 8 x 32 and 8 x 42 pairs by Nikon and Leica. I wanted something light, easy and good to pick up and go. I tried some others and the 8 x 28 Vipers were way better than others in their size and price range. They focus easily, the color rendition is superb, as is the clarity and definition. Color fringing is all but nonexistent and edge of field definition is very good. They are a touch larger than some in this group, but the tradeoff in optical quality is more than worth it. It has made me take a hard look at other Vortex models. Made in Japan and highly recommended.

Viper 8x28 - 06/17/2015

by Clyde D. from Tacoma,WA

Very pleased & impressed! I bought this product as a gift for my wife. At first, I don't think the idea of binoculars as a gift overwhelmed her. Once she tried them out, she was very excited and happy with
The weight and ease of use of the Viper model. They will be great for birding and travel. Delivery was
Timely as promised.

Vortex 8*28 binoculars - 03/27/2015

by Bill H. from New Braunfels Texas

I was disappointed somewhat in these binoculars.

I own 3 poro prism binocs in 6 through 8 power.
I also own 3 roof prism binocs in 6 through 8 power.
The six binocs prior to this purchase were in the 30 through 42mm objective lens range and in the 90 to 800 dollar price range.

Of my seven pairs of binocs, this little Vortex has the worst glare which is extremely obvious when viewing. This glare comes not through the objective but through the ocular lenses. All my binocs have the same straight-across eyecup so get the same stray light into the ocular from behind. This Vortex actually focuses the stray light coming around your eye and reflects it right into your pupil, unlike any of my other binocs which seem to lose that stray light somewhere else.

I purchased these binocs for hiking as they are well made mechanically and light. I would value them at about a hundred dollars, not near their purchase price. I did not return them because they really are light and that component is paramount on the hikes I want to take. I would not recommend them except to a backpacker who needs the low weight.

Go Anywhere Binos - 11/18/2014

by Robert from Columbus, Ohio

Use these binoculars when I'm on a long hike, kayak fishing, or photographing birds and other wildlife. While not quite comparable to a good pair of 8x42s, they are easy to focus, are very sharp, have reasonable close focus for butterflies and such, work well with glasses, and perform much better than the real little guys while not being too bulky. You don't mind having them with you all day and they are ready when you need them.

Good Buy - 01/06/2014

by Phillip D. from St. Louis area

Bought these for my wife - she hunts with me a lot and uses binoculars frequently for deer & turkeys. I also bought her a new S4 Lockdown to replace her Crooked Horn harness.

I haven't used them much, but she loves them - they're lightweight, very clear (much better than the entry level Leupold's) and the focus knob has the right amount of tension and really makes dialing them in very easy.

She also really liked the eye-cups - they adjust in and out easily by rotating them.

Personally, looks are important to me and I think they look pretty cool - very low profile hinge with a nice looking focus knob.

Nice pair but a little small for me. - 12/26/2013

by Steve from SF Bay Area

Vortex is always a quality product. I ordered these hoping they would fold down small enough to be carried in a pocket while hiking. Sadly they are a little to large for that so I returned them. But as far as the quality of the product is concerned it was well made, very sharp to look through and not made in China as so many of these smaller pairs are. I would recommend them provided you understand they do not fit in your pocket as some small pairs do.

Great binocular with a great warranty - 04/25/2013

by John from Texas

Two years ago, I was preparing for a 5-day backpacking and birding trip and wanted a quality pair of compact binoculars I could use for birding when I was camping and for bowhunting in the fall.

I had the chance to compare these side-by-side with Zeiss and Leica and Swarovski compacts in both sunlight and shade at the wonderful Audubon sanctuary near Portland, Or. After much time and consideration, I decided there wasn't enough difference between these and the more expensive brands to warrant the extra cost. I am always pleased with the image these provide when I bring them to my eyes, and I've been leading birding tours for over 20 years, so I've seen every kind of binocular there is to see. I also have 20/10 vision so my eyes are hard to please when it comes to good glass. These are very good glass.

Because I also use these for bowhunting 3-4 months each year, they are exposed to a lot of rugged use and extreme conditions that most birders won't put them through. Recently, a strap lug broke off mine and I returned them to Vortex for repair. They were replaced with a brand new pair at absolutely no cost to me, in about 10 days time. Thanks Vortex, for not only a great product at a reasonable price, but for customer service that is second to none.

Fantastic set of binoculars - 01/28/2013

by Al W. from Seattle

Very pleased with these. Small, light and good ergonomics. As usual the Eagle Optics experience was great.

great mini-B's! - 01/24/2013

by Steve H. from Davis, CA

These are the first small bins I've used where I can find the bird instantly, just as with larger bins. The image is clear and bright. Astonishingly, they have the same width of view as my Zeiss 10x40s, at least they way they sit on my glasses. When I compare both near and far views, the width is identical. I can't wait to take these backpacking.

Perfect Backcountry Binocs! - 07/29/2012

by Gail from Washington, DC

I am a birder and own multiple pairs of binoculars, but all my compact pairs were given to me by others and do not meet my standards for optical quality. I needed a pair for a recent backpacking trip and bought these, sight-unseen, based on the specifications and reviews. They were perfect for my purposes and I will use them time and again for years to come. I have a pair of good quality, much larger 8x32's, but the Vortex Viper beats them in terms of clarity, ease of adjustment, and of course, portability. I cannot tell the difference in the field of view between the 28's and 32's. The Viper is very comfortable to hold, easy to clean, and durable. I cannot recommend them highly enough!

good things in a small package - 07/10/2012

by RotDoc from Central Washington State

I purchased these binoculars for my wife's birthday. The optical clarity is superb. They seem to be well made and I expect them to last a long time. Overall, I think it was a great purchase.

My new favorite - 12/15/2011

by Vince from Oregon

First, these are more compact than mid-sized. They are smaller than you think and much smaller than the Viper 6x32. They have more eye relief than any other compacts I have tried but a bit less than the Viper 6x32 (even though the number is the same.)

The sharpness is very very good. They are on par with my Nikon 8x20 LxL and my Elite 7x26, but better eye relief. The focus has no slop and it's not too course or too fine. They focus down very nice.

These probably exhibit more flare than larger, expensive binocs but it's generally not a problem under average circumstances - only when the sun is close to your field of view. If I shade them with my hand they're good. Of course the field of view is also smaller than big binocs but I'm OK with it. These are keepers.

Overall, these are great binocs that I will use a lot. They are comfortable with glasses, yet compact and light weight. These are the ones I always grab.

Good product! - 09/28/2011

by M from Texas

Great viewing experience. Wide, clear view even with my glasses on. Lightweight and easy on the neck. Compares favorably with my Bausch & Lomb Elite 8X42.

Very nice glasses - 08/22/2011

by Big Steve from Seattle, WA, USA

I bought these for my SO to use for backpacking, mountaineering and ski touring. I have a pair of Nikon Premier 8x20's (which are great), and figured that it would be nice to have a second pair of trail glasses with a larger objective for dawn and dusk use. The Viper 8x28's have a crisp and bright image, very little pincushioning and virtually no edge distortion. The optics are generally equivalent to the Premiers in daylight, and the larger objective/exit pupil is very nice in lower light. Of course, no compact glass performs like a full size quality bino, but these are darned close. The fit and feel is very nice. Note that these binos do not fold down as small as 8x20 compacts from Nikon, Zeiss, Leitz, Swaro, etc. We are fully satisfied with these binos.

Vortex Viper 8x28 - 07/29/2011

by Martin from New Jersey

Being an owner of two Nikon binoculars - an E Series 8x30 and a compact 8x25 - I had the opportunity to compare these with the Viper. The Viper 8x28 is clearly superior to the 8x25 Nikon; and stacks up very favorably with the "classic" Nikon E Series glass. The great advantage of the E 8x30 is its three dimensional, wide field view - very easy on the eyes and satisfying in every way. The Viper is actually a tad sharper than the Nikon E - and has noticeably longer eye relief - making it a good choice for an eyeglass wearer like myself. It is also much more compact than the Nikon E. I am enjoying the Viper: very solid, moderate in weight, and compact for it's 28 mm objective size - and recommend it as a worthy choice for general use.

Best Waterproof Compact - 06/17/2011

by Smallmouth Fisherman from Cedar Falls, IA

I was looking for a waterproof alternative to my all-time favorite compact binocular, the Bushnell 7x26 Elite. The Vortex Viper 8x28 is not quite as bright, but it does focus significantly closer than the Bushnell, which is a boon to folks that enjoy watching dragonflies and butterflies. I wear the Viper when kayaking or fishing. This is a handsome looking instrument that is well built and feels good in my large hands. The 8x28 focuses very smoothly and renders a bright, clear image for such a compact design. If this was offered as a 6x28, I would buy it! I have recommended this model to several friends, and have loaned it out to birding companions (all were favorably impressed). The only suggestion for improvement is for the addition of tethered objective covers.

Thank you Eagle Optics for Compact Vortex Viper - 06/11/2010

by Wendy from Deerfield, IL

I am recovering from a shoulder injury and cannot use my full size binoculars due to weight on neck and shoulder. Eagle Optics recommended this 8 x 28 binocular which has the viewing quality and ease of use of my full size binoculars. Now I can go birding without pain afterward and my shoulder is healing! They were well worth the price and the service and advice was great! I love having a compact pair!
