Now, let’s go back to the beginning for a second – what is the magnification? This function increases the size of a subject that you observe from afar.
With or without adjustment ? It’s really down to what you’re using your binoculars for.
Pre-set binoculars , also called ‘fix focus’, are easier to use because there is no adjustment required. They are ready and raring to go! We recommend this design for family hikes with children – little ones can use them easily without having to change the settings. The only limitation of pre-set binoculars is that you must observe your subject from a distance of at least 20m to get a sharp image.
Adjustable binoculars provide a more precise, sharp image. The adjustment wheel can be set in a few seconds and lets you choose the focus, from far or near.
Of course, when you’re walking or hiking, your binoculars can quickly become heavy and cumbersome, whether they’re in your backpack or around your neck, so opt for lightweight binoculars (i.e. weighing less than 35g). It’s worth bearing in mind that the magnification affects the total weight of the binoculars. The higher the magnification, the heavier the lenses and therefore the heavier the binoculars. A pair of binoculars with a x12 magnification will always be heavier than x10 or x8 magnification binoculars.
