MM4 77 GA ED Fieldscope

    MM4 77 Fieldscopes are the latest evolution of the MM4 concept pioneered and developed by Opticron to meet demand for high performance lightweight space saving equipment.

    Designed & manufactured in Japan, the 77mm HDF ED optical system delivers a new benchmark for resolution and colour contrast and comfortably outperforms older Opticron 80mm models. What is more remarkable is the size and weight of the overall package. The MM4 77 GA ED is just 315mm/12.4” long and weighs 1250g/44oz fully armoured. These figures read like a 65mm which cannot deliver the light transmission or apparent resolution of this 80mm class device.

    Compatible with SDL, HDF, HR and MM3 eyepieces, existing owners can use eyepieces from other Opticron models with MM4 77 Fieldscopes.
