This is often but not always indicated on the rear face of the focus wheel What is My Binoculars MagnificationĪ binocular will almost always have the magnification (the number that precedes an x) displayed somewhere on the binocular. Size comparison between the 10x powered 32mm and 42mm Snypex Knight ED BinocularsĪbove is an example of two Snypex binoculars of different sizes but both have the same 10x magnification. So you can get pocket sized 10x22mm compacts, mid-sized 10x32mm binoculars, “normal” sized 10x42mm binoculars and then large 10x50mm instruments – all of which have a 10x power and it is largely down to the different sized objective lenses that affect their physical size. Sure it is common for very high powered long range binoculars to be large, but this is because high powered devices need to capture more light in order to deliver reasonably bright image (see my complete guide to the exit pupil for more on this) and so need larger objective lenses and has nothing to do with the magnifying of the image that takes place in the ocular lenses in the eyepieces. It is a common misconception to assume that a giant binocular has to be the most powerful and that compacts only have low magnifications. When considering a binoculars magnification, it’s important to note that the physical dimensions of the binocular have nothing to do with its magnification. Please note: For the purpose of this document, I’ll be using the terms power and magnification interchangeably. ![]() In this article I’m going to discuss magnification and in particular how a binoculars power (magnification) impacts your experience whilst using it. ![]() ![]() How a Binoculars Magnification affects your Viewing Experience
