The MM4 50 GA ED series continue to deliver the maxim; “smaller, lighter, brighter, sharper” to anyone searching for a supremely compact & versatile high quality instrument for long range accurate observation while on the move.
More Information

Designed & manufactured in Japan and constructed from lightweight materials, an MM4 50 weighs about the same as pair of 42mm binoculars and can be used without a support for crystal clear flat-field observation at magnifications below 20x. Unlike binoculars, they deliver stunning clarity and definition up to 36x when fitted with HDF T or SDL zoom eyepieces. Compatible with HR2/3, HDF and SDL eyepieces, existing fieldscope owners can use their eyepiece with an MM4 body.
