While many manufacturers of large binoculars tend to sell a 15x binocular, e.g. 15×56 or 15×70, Nikon seems to prefer 16x, as in this Monarch 5 16×56 (or e.g. the Action EX 16×50, see separate post). Its external dimensions and weight are identical with the 20×56 model, but with its lower magnification, the 16×56 has the larger field of view and a better correction of chromatic aberration, and for daytime use, when 20x is often too high a magnification due to air turbulence, the 16x may prove to be more useful for birding or long distance observing. The Monarch is an excellent all-purpose high mag binocular, esp. considering its price; of course, you cannot expect it to match the performance of more expensive premium optics such as the Swarovski SLC 15×56 (see separate post) or the Zeiss Conquest HD 15×56 (see separate post). Observers with narrow IPD beware: the Monarch does not go below 60mm, which, together with the relatively wide eyecups, limits the ease of view a bit.
