40x22 Compact Folding Binoculars FMC

Measuring just 11 cm when folded and weighing under 200 g, these 40x22 binoculars prioritise portability without sacrificing optical capability. The optical train features BAK4 prisms and fully multi-coated (FMC) lenses — a combination that improves brightness, reduces flare and enhances resolution across the entire field of view. The 40x magnification provides significant reach for outdoor applications, with a practical long-range identification limit of 2000 metres in daylight. The body uses a two-part polymer shell with integrated rubber overmould for secure handling and environmental resilience. The folding joint is precision-machined and tested for >5000 open/close cycles without loss of alignment or play. Focus is centrally controlled with tactile feedback and consistent resistance — no sticking or overshot adjustment. Eye relief is rated at 12 mm, compatible with most prescription eyewear. The exit pupil measures 0.55 mm, matching the human eye’s contracted daytime pupil size for efficient light delivery. Their size and weight make them uniquely suited to scenarios where every gram counts: ultralight backpacking, cycling tours, urban photography scouting, or as backup optics in a hunting vest. They complement — rather than replace — larger binoculars, serving as a ‘grab-and-go’ solution when speed and discretion matter more than absolute optical supremacy.
