4x20mm 4x20 Telescopic Scope for 22 Calibre Rifles & Air Rifle Gun Cross hair Scopes

Product Information

The Pentax VD 4x20 WP binoculars and thus by default, each of the monoculars and the spotting scope have a waterproof construction, which is rated at JIS Class 7 meaning that they protected against immersion of water at a depth of one meter. As you can see in the table below and included comparison images, as a binocular and comparing them against others in this compact size class, they are to date one of the most compact, compacts that I have ever come across! I have an in-depth article on everything you need to know about this relationship between your pupil size, the exit pupils, and prevailing light conditions that I highly recommend you look at, but in brief, the exit pupil size comes as a result of dividing the aperture or in this case the objective lens size by the magnification. As a 4x binocular and the resulting very stable view you get with such a low magnification, unless you were using it for digiscoping, it would be unlikely that you would want to mount the binocular or indeed the monocular onto a tripod. However, even though it is quite possible to use it from the hands, when converted into the 16x Spotting Scope it certainly helps make it a worthwhile thing to do if you want to eliminate image shake and thus be able to better study the detail of a highly magnified image.

So, no lens covers and no cleaning cloth, and whilst it is quite common for compact binoculars to come with a smaller array of accessories than full-size instruments, I do feel that it is a shame that Pentax (a predominantly camera and lens company) don supply these simple, but useful additions to help ensure you are better able to protect the optics. As well as very minimal color fringing, I never noticed any other sorts of image distortions, and once correctly focused the image remains sharp from the center, right out to the edges with only an extremely minimal amount of softening right at the edge of the view which is really impressive. Yes, by keeping the magnification down to just 4x certainly helps, but Pentax also obviously uses very good quality glass and coatings as well as their renowned high level of optical expertise and precision on these and it really does show. The level of Anti-Reflection Lens Coatings is in my opinion one of, if not the most important things to look for when buying binoculars and so it is important to note that the Pentax VD is Fully Multi-Coated: So will the Pentax VD 4x20 WP Binocular / Monoculars / Spotting Scope be the ideal solution for everyone and everything, no absolutely not, but what I will say is that they are extremely versatile and I can see them being of great use in a wide variety of applications: Ideal Uses & Usersat 1,000 yards or 175m at 1,000 meters, I have already spoken about just how expansive the view you get when looking through the Pentax VD 4x20 WP Binocular or Monocular, but let's now put this into some sort of context by comparing them some other compact binoculars: I have to say that before receiving them, this is the one area of the Pentax VD 4x20 WP Binocular / Monoculars that worried me as no matter how good the optics were, had Pentax not got this part right, it would have been an instant deal-breaker.

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.

Features

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. Just one point about the Velcro is that if you are sneaking up to timid birds or other wildlife, you need to be careful when opening so as to not make too much noise. With what is a predominantly a close-range instrument, perhaps a more silent (but less secure) magnetic closure would be better. Leupold VX-Freedom 1.5-4x20 Rifle Scope. The new VX-Freedom delivers the legendary Leupold performance and dependability hunters and shooters have demanded for decades, combined with a host of new and improved features. The VX-Freedom is guaranteed to get the job done every time.

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. Each scope design has to survive 5,000 impacts on the Punisher, Leupold’s recoil simulation machine. The force of each impact is 3x the recoil of a .308 rifle. If the scope doesn’t perform in any way during the tests, we make adjustments to the design and test it again. 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.At just 4x (as a binocular or monocular), there is no denying that even when compared to the average, the magnification on this Pentax VD Binocular/monocular is very low and quite extreme. If it is a compact scope you are after as the primary use, then I would suggest that to be truly effective and allow you to fully enjoy the view, you will need something a little larger - so something like the Hawke Endurance 12-36x50 is a good example of a compact spotting scope.
