These are really great. I wanted a set of binoculars for the sailboat... I'd loved my Razor HD 10x42's that I've had for 6 or so years but I'd often forget them at home. So I needed a specific set of binos to leave at the boat. I'd compared my Razor 10x42's to the quintessential Steiner 7x50's that are often considered the perfect marine binocular. My 10x42's had a larger magnification (10 vs 7 power) but had quite a bit wider field of view. The wider field of view helped provide better context and allowed you to stabilize with your eyes better while the boat moved. However, the Steiner's were a bit brighter when night fell. Not by a lot but definitely brighter. Should be said that I was comparing to the lower end Steiner's...

When trying to find unlit crab pot buoys at dead night with a new moon off shore while running the motor its a bit of a stressful time. My Razor HD 10x42's were my go to bino's because the slightly higher mag worked pretty well but I was often wishing for the brightness of the 7x50's. These Razor UHD's are that perfect mix. The improved prism design makes them a good bit brighter. The enhanced lens coatings help make them brighter and the fact that I bought the 8x42 makes them brighter. These make it much easier to see and I think that only a FLIR system would do a better job. But this way it is always ready to go, never needs recharging, and costs less for better opitcs that will last longer.

As I compare my Razor HD 10x42 to my Razor UHD 8x42 I find them to be very similar during the day. They both have slight CA issue when looking at a very dark item against a bright background you will see a bit of purple/green fringing but only when brightness differences are stark and you're only annoyed by it if you're looking specifically for it.

However, as the light dims the differences really become a lot bigger. What I don't know for sure is how much of the difference is because I'm comparing UHD to HD and how much of it is simply because I'm comparing 8x42 to 10x42... That all being said I bought the UHD 8x42's for $930 and at that price I feel like I really got a wonderful piece of glass.

Lastly the larger form factor and the ergonomics of the larger binocular will suit our application to using these on the boat well.. They are easier to stabilize while underway with the seas are moving you around. As well thankfully their larger weight isn't something that I have to carry around very much while on the boat. So while I'm extremely happy with my purchase I still prefer my Razor HD 10x42's for use on stable land and/or when I have to pack them around a lot... The weight and size savings for the HDs is a big advantage when you have to carry them. So I FULLY understand why Vortex is keeping the Razor HD and the UHD lines at the same time.

So somehow Vortex has sold me the best pair of binoculars I've ever owned and could ever imagine owning twice. And the most amazing part is that with Vortexs' warranty I'll probably own these for the rest of my life.

The edge to edge clarity is perfect, depth of field and resolution is unbelievable, I compared these side by side to the Swarovski 12x50's and the Vortex are better, hands down, coupled with the price delta...this is an unbelievable pair of binocs.

I was in the market to replace my 16+ year old Audubon Birder's Bausch & Lomb 8x36 binos that I've been using all this time for birding. I wanted to get "the last pair of birding binos you'd ever need in your life" so decided to really go upscale. The cream fo the crop IMHO are the Swarovski ELs, 8.5x42 which commonly sell for >$2,500 which I couldn't justify the price, so started looking for good binos in the $1200-$1500 price range. Did a lot of research and finally decided on the Vortex Razor UHDs in 8x42.

I've had experience with Vortex's riflescopes, which are definitely and deservedly at the high end of scopes, and this is why I focussed on Vortex Optics, however, I was looking at them from the perspective of a birder, *not* a hunter, as bino demands are different in each case.

I was surprised to hear a longtime birder friend of mine on the other end of the country had picked up the Vortex Viper glasses years ago, and he gave them high praise... so then had to decide on the HD vs. the newer UHD binos. There's pros and cons for both, but decided to go with the UHDs

After a week of using them, I do NOT regret paying up. First, I think the optics are on par with the Swarovski ELs. The "hype" I've read about these glasses turned out to not be hype. They really are that good!!!! Amazing low light detail. Sharp contrasts, no color aberration.. holy moly.. they WERE that GOOD!!!!

They feel good in hand. Amazing long eye relief and did I mention crystal clear vision?

However, I think these glasses are definitely designed with the hunter in mind, not the birder, but I don't think this is a deal breaker at this price point. Let me tell you the pros and cons from a birder's perspective.

1. Optic quality on par with the much, much more expensive Swarovski ELs. These definitely compete with the other high end optic mfgs like Leicca and Zeiss. They weight a couple oz's more than the ELs, but it's not really noticeable. The optics make these *perfect* birding binoculars at this price range. Zeiss.. Swarovski? Vortex has sent a shot over your bow.!!!!

2. Argo-purged, waterproof. Non-fogging, rubber armor. Everything a birder needs for a long day in the field.

3. Comes with a chest harness for all day carry. It's well made and comfy, but jury is still out for me on this.

4. "Slow" focus wheel, Makes it easy to make precise focus adjustments without overshooting.

5. Long eye relief and "locking" diopter. Perfect for the eyeglass wearing me!

6. 8x glasses have a 420' FOV at 1000 yards. That's pretty amazing and makes finding and zeroing in on bird motion a breeeze.

7. Close focus!!! (<5 ft.)

8. Vortex Warranty. It's about as good as it gets. Covers everything except "theft" and "loss". Vortex Optics also has an excellent customer service reputation.


There's really few cons with these glasses. I'm only mentioning them here because it needs to be considered by the birder. A couple of their "pros" might actually be "cons" for the birder

1. Weight. They're 32oz. These are a couple ounces heavier than the ELs, but they are heavy for all day neck strap wear and other high end glasses don't weigh this much. I don't think I'd take these on day hikes if birding wasn't my primary objective. I could even seen hunters being a bit put off by this if they're trekking all day. Consider this. However, the weight is partly because of the Abbe-Koenig prisms that are used. Long optical path, heavier, but the advantage is excellent low light performance and crystal clear optic paths. Also, comes with a carry chest harness, so a lot of the weight disadvantage is negated.

2. "Slow" focus. One fo the strengths of the slow focus may make it a pain for going from one distance to the extreme other quickly. It takes >2 full turns to do this and if you're glassing near, then suddenly a fast-moving bird is soaring in the sky? You might miss it because of the amount of focus turns required. Quick, near-to-far and vice versa focusing is important to a birder and MUCH less so to a hunter. We'll see if this can be mitigated by how I use them in the field. The slow focus makes it easier to get crisp focus on minute distance changes without overshooting though.

Hope this helps another birder on making a purchase decision. At $1500+ these are excellent.. *excellent* glasses for the money. Optics on par with "paradigm" glasses costing >$800 more.

One comment for hunters (and I used to be one....). I think you should go with the 10X model. The light gathering power of these binos is awesome and the 10X mag will hit the sweet spot of magnification needed for that activity.

Excellent binoculars, very clear and bright image, the 18 power increments make it an incredible binocular, you have to use them with a tripod to enjoy this new optics to the full, having it in my hands is very comfortable for its design I love these binoculars. Congratulations to the Vortex optics team, the Focus camera store is very responsible to send them, 100% recommended.

We have the 8x42 mounted on the vortex Pro tripod and setup in the living room. When something comes by we like I get the phone out and snap a pick with the phone pressed up against the binos. Perfect clear shots. The clarity, brightness and ease of use on the vortex UHD are top notch. The front lens caps snap in vs the lower end model Vortex caps that slide over the lens. Love the snap in caps because you can really squeeze the set in tight for smaller faces.

A little on the heavy side, but super clear.

Was excited to get these new binos but had to return them because the cap for the tripod mount was broken. the screw was stuck in the hole. For $1600+ i would expect beter quality control

Looking through these binoculars is literally—and I can’t emphasize this enough—like opening your eyes and seeing the world for the first time. The field of vision and clarity on these are just stupid. My friends hate me, among other reasons, because I will not shut up about these binoculars. Now, I’ve never actually seen out of the Swano EL’s or Zeiss whatever’s that directly compete with the Razor UHD but I don’t care if I ever do.
