## Overview

The Optics Diamondback 10x50 Roof Prism Binocular delivers professional-grade 10x magnification with 50mm objective lenses, enhanced by fully multi-coated optics and phase correction for superior clarity. Built tough with waterproof O-ring seals and argon gas purging, it resists fog and moisture in any environment. Designed for comfort and precision, it features adjustable eyecups, a center focus wheel, and comes complete with protective accessories, making it the ultimate companion for hunting and outdoor exploration.

## Description

Taking its lead from the Diamondback, this rugged binocular is striking in how well it detects life in low light. Huge field-of-view, the largest in its class, with enhanced fully multi-coated optics, phase-corrected prisms, waterproof and fogproof construction, soft tapered eyecups, and rugged rubber armor. It's all there.

## Features

- O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable waterproof performance in all environments while argon gas purging prevents internal fogging over a wide range of temperatures.
- Fully multi-coated on all air-to-glass surfaces increases light transmission while phase correction coating enhances resolution and contrast.
- Adjustable eyecups can be twisted up or down for comfortable viewing with or without eyeglasses.
- Center focus wheel adjusts the focus of both binocular barrels at the same time while the diopter (located on the right eyepiece) allows the user to adjust for focus differences between each eye.
- Rainguard, tethered objective lens covers, comfort neck strap, and deluxe custom-molded carry case are all included in the box.

## Questions & Answers

**Q: Which is better for big game hunting? The 10x42, 10x50, or the 12x50? (All diamondbacks)**
A: This is pretty subjective and personal, but here is the lowdown. 10x42 and 10x50 are the preferred sizes for handheld use. 12x50 is great for big, open areas, but is often difficult to keep steady withouth some kind of support and can limit your field of view (zoomed in too much) when trying to find a target quickly. That said, the difference between 42 and 50 is that the 42s are smaller and weigh less, but the 50's will get you a little better low light visibility and possibly clarity.    I have the 10x50's for hunting out west in the sagebrush steppe and mountains and love them.

**Q: Hello, would these be good for astronomy?**
A: Someone answered that you could buy a "good telescope" for the same amount. NO! I taught astronomy for 30 years and 10X50's were the binocs of choice for my classes. I strongly recommend a pair of binoculars over a comparably priced telescope. Now, as far as this model, I do not know. I was checking them out to see the FOV. You definitely want wide angle. There are also some excellent books on Amazon dealing with "Binocular Astronomy".  Clear skies!

**Q: what year are these**
A: Not sure. I bought them for 25 yr old grandson in August, 2016.

**Q: what is the color ?**
A: Olive

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value
*by K***N on June 23, 2025*

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).

### ⭐⭐⭐⭐⭐ Reach out and view
*by V***  on July 13, 2025*

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.

### ⭐⭐⭐⭐⭐ Superb birding binoculars for harsh field conditions
*by J***I on July 16, 2025*

We’re birders but we’re also cheap. Some of our crazy friends have binoculars worth thousands of dollars (really). When we go out birding, we usually are in a harsh wilderness environment. Sometimes salty with sea spray, sometimes icy with subzero temps.Over the years, we’ve tried a half dozen of the “next best level” birding binoculars, meaning the ones that are under $1,000. Many share the same form factor as this 10x42 waterproof Vortex model.Hands down though, this one takes the cake. Superb optics, bright light capture, sturdiness, and durability. Slightly heavier than our next favorite but quite a bit better. Comfortable to hold and to view with even with glasses. Very little distortion even on the edges of the visual field.Over 25 years of avid bird watching, these are the binocs we grab first.
