As a spotting scope with a 16x magnification, this field of view is obviously greatly reduced, but Pentax does not state what it is, so I can't comment too much other than to say it does not feel excessively narrow. Even more impressive for a compact and especially at this price is the fact that the auxiliary prism has a dielectric multi-layer mirror coating applied to it this super-high-reflection surface has the effect on improving the level of light transmission for brighter images as well as improving image quality by reducing flare and ghosting. As the Pentax VD 4x20 WP splits apart, they obviously could not have a single centrally located focus wheel as you would find on most binoculars.
I also really like how this system results in the central hinge working and feeling exactly like a standard pair of binoculars and thus adjusting the IPD to match the distance between your eyes is no different than normal. The game takes place in two parts, Panel 1 and Panel 2. When you play, you must fill in both panels, as explained below. Playing Gosloto 4/20 Whilst a very minor point, the two thumb indents on the underside of the body show good attention to detail from Pentax as they just add to the comfort when holding them as well as just encourage you to hold them in the right way and in the right place. This all adds up to make for an incredibly useful and versatile instrument, that I can see being a good option in the following areas: Firstly, any movement you make when looking through a binocular or monocular gets magnified by the magnification and this is one of the biggest problems with high powered binoculars, because whilst in theory, the highly magnified view can give you a very detailed image at distance, any tiny movement you make with your hands causes a relatively large amount of image shake and thus you cannot actually get to see that detail unless you mount the binocular onto a tripod or get a binocular with an onboard image stabilizer.Absolute waterproof and fogproof integrity means it's ready to perform in the field, in all conditions. One area of these binoculars and indeed the monoculars that is somewhat different from the norm is when it comes to focusing. Well, what if you could have your cake and eat it and by this I mean you didn't have to choose between them? Pentax VD 4x20 Binocular & Monocular Review
As a binocular or monocular, with such a low magnification to the view and the use of good quality optics, I was never expecting there to be much color fringing visible and indeed this turned out to be the case. The exit pupil also goes from a large 5mm right down to a very small 1.25mm in size. This has the effect of greatly reducing the image brightness in low light conditions as this shaft of light exiting the eyepiece is far smaller than what the pupils in your eyes will be dilated to. Whilst it is still usable from the hands, the much higher 16x magnification makes it noticeably harder to keep the image still and shake free, however, the scope is very easy to fit onto a tripod using a standard tripod adapter and is something that I would recommend doing if you plan on using it in the state often or for long periods. Instead, they incorporate a focus adjuster on each barrel. Many binoculars actually do have a similar system and are often referred to as Individual Focus Binoculars and are often used for marine and astronomy binoculars amongst others, however, these are basically just double diopter adjusters located on both eye-pieces. Sure it is thin and un-padded, but on such a small binocular/monocular this is really unnecessary and would only add unwanted bulkiness and clutter to the system.A compact binocular that splits into a pair of monoculars, that you can then convert into a 16x spotting scope! The Pentax VD 4x20 WP is a set of optics that the Transformers would be proud of, and in this review I test them to see just how good they really are: Binocular vs Monocular Disperses recoil energy for unrivaled durability and performance with ultra-lightweight construction.
Interestingly, as small as they are, you can also see in the table above, in comparison to other compact binoculars, they are actually amongst the heavier instruments out there. A few months ago I put together an article and accompanying video where I compared a compact binocular to a small monocular to see if we could discover which was the better option for different uses, users, and in different situations.
Features
Preppers - Survival binoculars that are easy to store in your Bug Out or Get Home Bag and you can use the spotting scope at longer distances if needed As binoculars or a monocular, at this size level, these are very tough to beat, as a spotting scope, the Pentax VD 4x20 WP is a little less impressive, but even so, with realistic expectations it will certainly have its uses. So whilst fully sealed, I did get confirmation from Pentax that they are not filled with a moistureless gas like nitrogen or argon, and thus the internal optical surfaces maybe a little more susceptible to fogging up, however at the time of writing, I have yet to have any issue with this. I will of course update this should this change. When you convert the Pentax VD into a spotting scope, it is not just the body shape that changes, but because the magnification goes from 4x to 16x, the characteristics of view are altered in many ways: This guide explains how to play the Gosloto 4/20, one of Russia’s most popular and modern lottery games available.
In sharp contrast, the view you get through these is incredibly stable, even when comparing them to a 10x or fairly moderate 8x binocular, the difference is instantly noticeable.
Product Specification
The beauty of these is if by any chance, you deem the binocular (which is tiny anyway) to be too big for your needs, you can just break it in half and simply carry about one of the monoculars. This is all well and good if your intended use and the overall conditions remain the same, but in my experience, this is rarely the case.
Great Deal
