As to the Vortex warranty, it comes down to having a binocular or its remains to send to Vortex for warranty repair/replacement. Vortex will replace much I don't think they should. For example, leave the binocular on top of the car and drive away, Vortex warranty covers you. If Dennis could retrieve the binocular from the river, he may be in luck, if not he's probably out of luck. I have an acquaintance who is a recently retired Vortex dealer, and he has many tales of what he has sent back to Vortex and what they did with the returned binocular.
Now I had a chance today to go hands on with a new Vortex Razor UHD 10x42. Side by side with my Maven B 2 9x45. It takes no imagination or great leap of faith to tell where the inspiration for the UHD came from. Aside from the obviously identical form factor of the frame and different color and texture of the armor, they pretty much look identical. The quality of the images are virtually indistinguishable as well. There is a bit of apples to oranges in that the objective size and the magnification are different. It was a gray, rainy day and take this for what it is, a first impression.
I hesitate greatly to seem to agree with Dennis, for his opinions are so ephemeral , his stance the UHD may change by the end of the thread. But as he currently expresses his opinion, the UHD is a solidly built binocular, with superb optics. Both of which are alpha worthy in comparison with Zeiss, Leica, and Swarovski. The same thing applies to the Maven B 2. If I had a UHD, would I be interested in a B 2? Probably not. If I had a B 2, would I be interested in a UHD? Again. probably not. If I was in the market for this sort of a binocular, which would I choose? At this point I can't say for adequate time with both had not occurred.
There are a couple of things which may not bode well for the UHD. The first is the focus, which is counterclockwise to infinity, is excruciatingly slow. Far too slow I think to appeal as a dedicated birding glass. It was not possible to get an accurate idea of how many turns of the focus wheel the UHD had, but it took at least twice as many finger pushes or pulls to go from close to infinity and back as it did on the Maven. Once past about 60-75t feet, again distances were not able to be accurately measured, the Vortex became better, but for close in birding, far too much time and effort would have to be applied to the UHD focus as desirable. The focus was also extremely stiff. I would not put a lot of stake in this, as it may well ease up wit use. Perhaps Vortex could lighten it up if sent in to them, but I don't know. Just trust me that this one was stiff enough to discourage many users. The close focus is around four and a half feet. I can just about focus on the toe of my boot.
The second thing, which I can only note as an observation, is the extension of the eye cup. All the way out was fine for me, but I don't wear glasses with binoculars. They certainly feel and act solid enough, but there are only two positions. All the way down and all the way up. The potential problem lies in the fact there is only maybe 3 mm of total movement present. How this will seem for various eye glass wearers, I can't say, but check it out before you buy.
They are a bit on the large side, but I have little sympathy for those thy say "too big" before using them. I realize size is an issue for a lot of people, but in spite of earlier comments on their being awkward, I find them, like the B 2, to be quite well balanced and easy to center your object when rapidly brought to bear on your target.
The thing with evaluating binoculars is to ignore that it says something like Vortex or Maven and prejudge them. Likewise it is best not to prejudge because it has the brand of a favorite product. Just let the binocular tell you its tale. Aside from the focus, the UHD tells a pretty good story
The UHD, like the Maven B2, would surprise no one if it came in the appearance of a Zeiss or Swarovski. I note that the price of this one, at the local Sportsman's Warehouse was $1,599. I see the Vortex site starts of with the 8x42 at $2,099.
