Optics Diamondback 10x42 Roof Prism Binocular

I have owned many pairs of binoculars from very large astronomical binoculars to very compact ones and in between models over many different manufactures. These are the finest binoculars I have ever purchased. Compact, powerful, great light gathering power, just plan very fine optics. The right size for travel, so I am in Mazatlán Mexico watching whales from my 10th story balcony.

Excellent in every way, and at this price... well, a bargain! I find the views bright, sharp, and completely without residual color fringing. The collimation seems perfect, so there is no eyestrain at all with prolonged viewing. The field of view is in good accurate sharp focus from the center of the field of view to edge of the field. The apparent field of view is huge, wide, and this heightens the perception of the 3-D effect that the binoculars give (it's clear that the eyepieces are a wide-field-of-view design-type). I also use the binocs for stargazing, and find the star images very sharp and without astigmatism or flaring, a stringent test for any optics! Viewing very bright objects such as the moon does not result in ghost images or multiple images: the anti-reflection coatings on all the optics and internal parts thus seem very efficient and effective. And I see no evidence of internal reflections from scattering when viewing bright objects: clean! The weight of the binocs is good, and not excessive, and they feel very solid; the focus control is easy and conveniently placed, and the variable diopter adjustment on the right-hand eyepiece is easy to adjust and it "stays put" once set, yet is always easy to re-adjust (say, when you hand the binocs to a friend with differing eyesight details). I'm very happy with these binocs, and will use them in all applications where 10x42mm binocs are appropriate, and especially in birding and Astronomy. I purchased a Vortex binocular Harness strap for easy carrying in the field, although the neck strap already included with the binocs is very fine and has a nice comfortably padded neck-piece cushion. The included binocular case is good, but my pair will spend most of its time out in the open and ready to use (read, "grab") in an instant. Again, this is a bargain and really a beautiful marriage of very high optical quality and mechanical design & implementation. Kudos!, Vortex. The 10 x 42mm Vortex Diamondback binocular is a hit with me, a retired Astronomer who appreciates fine optics and mechanism.

Excellent clarity. Nice binoculars. If you’re hunting, I would consider these appropriate for a fixed stand. They are a bit big and heavy for stalking. I would personally go with the 10x40 for stalking (I own both the 40 and 50’s).

Great product. Perfect for bird watchching. Easy to adjust. Great price.

Excellent optics. No color distortion. Lightweight for the lens size. Easy to adjust for focus, clarity. The objective lens covers are kinda loose and need to be tightened up with silicon glue dots or lines on the inside edge of the cover. Also, the cover anchors slip off the barrel of the lens tube, so they have to be attached with silicon glue or rubber cement. Use black permanent marker on the blazing white Vortex emblem on the strap and you have a really nice tactical field glass for not too much money. Nothing rattles or makes any noise. Small enough to fit into a decent size pouch on your MOLLE pack.

Three years ago I bought Vortex Diamondback binoculars for me and my wife. I love them. The low light clarity is amazing. Had to return my wifes binocs because they were two wide for her eyes and gave her a headache. I contacted Vortex with this problem. They responded immediately to my email with a phone call. The lady explained interpupillar measurement and how it affected binoc type selection. Called my wifes optometrist and got this measurement. These binocs wouldn't work for my wife because her eyes were too close together for this style of binocs. The lady at Vortex sent me another type of their binocs for my wife to try but they were too wide for her as well. Since I bought these well in advance of hunting season and I was outside the return window for Amazon. They were virtually unused. Vortex took them back and wrote me a check for what i paid Amazon and PAID the return freight.They really wanted my business but they didn't have any that would fit her (they weren't making a porro prism style binoc at the time). I let my wife use my older Nikons in the porro prism style. When hunting together she had to quit observing the deer five minutes before i ran out of light looking through my Vortex binocs. As you might know the last light of the day is prime time for big bucks. So when I saw they had this pair of Vortex Porro prism style and they would fit her interpupillary measurement I got them for her. She had them out at first light the next morning and late the next evening, We also went to our hunting property and got in the blind just before dark and watched the deer. She loves them. They have great clarity and field of vision. The lifetime no questions asked full repair warranty is HUGE. But they are just real good folks who made a great impression on me with their service.

I bought two pairs. They’re really good for the money.

These vortex binoculars works very well. The magnification is great, the view is clear. I consider this product to be of good quality. I also like the color and weight.
