Magnification refers to how much larger an object appears when viewed through binoculars compared to the naked eye. Common magnifications range from 8x to 12x.

Objective Lens Diameter

The objective lens diameter determines how much light the binoculars can gather. A larger diameter means brighter images, especially in low-light conditions.

Field of View

Field of view is the width of the area visible through the binoculars at a specific distance. A wider field of view allows you to see more of the scene at once.

Prism Type

Binoculars utilize prisms to correct the orientation of the image. The two most common prism types are Porro prisms and roof prisms, each offering its own advantages.
