Most people use binoculars to observe distant objects and so this will be of little importance. However there are also some uses where having a very close minimum focus distance is desirable. Like the magnification, the objective lens diameter makes a big difference to how a binocular performs and as a result which areas it is most suitable for use. Pistols and SBRs Archives". CMMG Inc.

Tiny lenses (21mm / 22mm) are for those requiring the smallest, most lightweight instrument possible, but be aware this comes at the expense of image brightness and potentially image quality as well.It is not that often that I get a fairly uniquely designed binocular to review, so when the guys at MINOX asked me if I wanted to review their compact fixed focus BD 7x28 IF binoculars, with its open bridge design I was immediately interested. What the table below does highlight is just how wide a field of view these binoculars have and indeed just how poor their minimum focussing distance is. Very closely related to the objective lens sizes is the size of the shaft of light exiting ocular lenses that then passes onto your eyes. Known as the exit pupil, it’s size on a Roof or Porro prism binocular is largely determined by dividing the lens diameter by the magnification.

Retrieved October 19, 2009.The advantage of this is that it saves time by not having to focus on every object that you look at. The other main advantage is that because there are less moving parts, fixed focus binoculars tend to be more robust than traditional centrally focused binoculars. On the down side, their minimum focussing distance is very poor in comparison to most binoculars where you can make focussing adjustments.

Compacts are very versatile and ideal for general use, nature, sporting events, wildlife observation & birding at close to medium ranges: Because these are fixed focus binoculars (often mistakenly referred to as self focusing or auto focus binoculars), once you have set each individual eyepiece to your particular eyesight and the binocular is thus focussed to the hyperfocal distance, you then no longer have to make any further adjustments and the binoculars will provide you with sharp views of everything from 20 metres away to infinity. Fixed focus binoculars like these have a large depth of field allowing your eyes to make the adjustments rather than the binoculars.

These Minox binoculars feature pull-out eyecups, which is a little different from the more commonly used twist-up eyecup design found on the majority of binoculars. They work really well and seem to be made from something like brushed aluminium. On top of this they then have a thin soft rubber coating on them which makes them feel fairly comfortable even when pushed quite firmly against your face. a b c d e f g h i Sterett, Larry S. (2005).

These compact Minox 7x28 binoculars are 100% waterproof and have had all their internal air replaced with a dry nitrogen gas. The nitrogen helps to stop the interior optical surfaces from fogging up due to rapid temperature changes or in areas that have high humidity. Apart from moisture, waterproofing also prevents any dust or other small particles from entering the binocular in dry climates. Once again this helps when storing them in places like the cubbyhole in my car which can get very dusty. a b c d e f g h i j k l m Forker, Bob (May 28, 2008). "The 5.7×28 FN". Guns & Ammo. Archived from the original on 2010-01-02 . Retrieved October 19, 2009.Thus even if we take the “largest compact” with 28mm lenses and combine it with a relatively low power, say 8x, you still only achieve an exit pupil of 3.5mm (28÷8). The 15mm of eye-relief is pretty good for a compact binocular and should also be enough for most people who wear glasses to use them without having to remove them. Because of the pull-out mechanism, they don't have any fixed intermediate stops, which for some people may be an issue. Although because this pull out action is fairly tight, you can actually stop the eyecups at any distance between fully retracted and fully extended, but this setting could be accidentally moved if you pushed them too firmly against your face. Non-eyeglass wearers will just use the eyecups in the fully extended position. Their small size, low weight and the very open bridge design meant that taking them on long walks and hikes in the mountains was as comfortable as it gets. Their body design also made them much easier and more secure to carry them in one hand whilst climbing up or down steep and difficult terrain, this helps to ensure that both you and your optics remain undamaged! a b c Miller, David (2001).
