MM4 77 GA ED/45 Fieldscope 41230.

MM4 77 Fieldscopes are the latest evolution of the MM concept pioneered and developed by Opticron over the past 25 years to meet the ever growing demand for lightweight, space saving high performance field equipment.

Combining all the features that have made our 50mm and 60mm travelscopes the #1 choice for thousands of users the world over, the MM4 77 GA ED/45 delivers our maxim; “smaller, lighter, brighter, sharper” to a new audience.

These "80mm users" generally want the maximum brightness and magnification available when viewing or recording birds and wildlife from a fixed position.

Designed & manufactured in Japan, the all-new 77mm HDF ED optical system delivers a new benchmark for resolution and colour contrast and comfortably outperforms many older Opticron 80mm models.

What is more remarkable is the size and weight of the overall package.

The MM4 77 GA ED/45 is just 320mm/12.6” long and weighs 1259g/44.4oz fully armoured.

These figures read like a 65mm which cannot deliver the light transmission and apparent resolution of this 80mm class model.

Recommended eyepieces include the 40862M HDF T 18-54x and 41270M SDLv3 18-54x.
