About The Bino List
The Bino List compares 142 binoculars from 21 brands on the optical specifications that decide what you actually see — magnification, objective diameter, exit pupil, field of view, close focus and eye relief.
Why optics need a comparison site
Binoculars are sold on two numbers — 8x42, 10x50 — that tell you almost nothing about whether a pair will suit you. Eye relief decides whether they work over glasses. Exit pupil decides whether they are usable at dusk. Field of view decides whether you can follow a bird in flight. None of those appear on the box, and they are the numbers that separate two pairs at the same magnification and the same price.
Where the specifications come from
Optical figures come from each manufacturer's published specifications. Where a value is derived rather than stated — exit pupil, for instance, is objective diameter divided by magnification — we calculate it consistently across the catalog so the column is comparable rather than partly blank.
Glass type, coatings and prism design are recorded as stated. We do not infer optical quality from price, and where a manufacturer is vague about coatings we leave the field empty rather than filling it with a guess.
Independence
Some links here earn us a commission at no cost to you. As an Amazon Associate we earn from qualifying purchases. No optics brand pays for placement or for a better write-up, and the premium European glass that often wins its category is largely sold through dealers that pay us nothing.
