Radial tyres do however tend to be more expensive than crossply alternatives, so could be viewed as an investment that will pay off in the long run.

The long eye relief offered in all Pentax Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain. Exterior rubber coating: This sophisticated optical design is critical to low-maintenance and long life guarantee. Exposure to air-bourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality. Nitrogen purged As with most roof prism binoculars, the diopter adjustment is located on the right barrel, between the eyecup and the barrel. This is used to correctly focus the binoculars to your particular eyesight and only really needs to be set up once when you use your binoculars for the first time. Hopefully, I have been able to demonstrate that even within the subset of compact binoculars, the combination of the lens size and magnification has a big effect on its performance and making the right choice for your particular needs is important. here I have a very good set of 18.4x26 ( rears) + 411400x20 ( fronts )turf wheels and tyres off a same 70, deutz, lamborgini, and some ford tractors

Image brightness (and quality) is also very dependent on the quality of the optical system and their transmittance levels. Good coatings on the lenses and the prisms can double the amount of light that gets through the binocular, when compared to those that have none or poor quality coatings and as we have already discovered these Pentax binoculars use very good quality glass and coatings and that is why they produce such a good quality and bright image even though they have relatively small 28mm lenses.

The metric sizes (420/85R28) tell you the PROFILE percentage after the width, here it is 85% profile (this means the side walls on the tyre are 85% as tall as the width of the tyre). This profile can be ignored if your tyre size if written in imperial as it is not given. With both sizes the last number is the RIM (the diameter of the hole in the middle of the tyre) in inches (28 inches in our example). The first number is the tyre WIDTH (know as Section Width), and in our example it would be 16.9 inches or 420mm. The 'R' if presents means you have a tyre of RADIALconstruction, and the '-' if present means the tyre is of CROSSPLY construction. Clean your tires: Clean and wash your tires after use.

Their optical performance is very good and they compare very well with compact binoculars that are far more expensive than these.

Or to put it another way, you are often able to see more at greater distances with more powerful binoculars. The field of view for these 9x28 binoculars is 98m at 100m / 294ft at 1000 yards (5.6°) - which is pretty good. As suspected it may not be quite as wide as the very best 8 compacts out there, but is better than most 10x ones which is exactly what I think Pentax set out to achieve. Their maximum eye-relief of 18mm is excellent and and they easily make it onto my list of long eye relief binoculars. It also means that this should be more than enough for most people who wear glasses to be able use these optics without having to remove their glasses and still get the full field of view without any vignetting.
