MM4 77 GA ED/45 Fieldscope

    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.

    Compatible with SDL, HDF T and HR eyepieces, existing fieldscope owners can use eyepieces from other Opticron models with MM4 77 Fieldscopes. Recommended eyepieces include the 40936M SDLv2 18-54x and 40862M HDF T 18-54x.

      MM4 77 GA ED/45 - Tim Sexton

      15 August 2019

      A video review by Tim Sexton of Nottinghamshire Wildlife Trust.


      MM4 77 GA ED/45 - Mike Alibone

      01 August 2019

      The MM4 77 is unique to Opticron – no other brand has access to its design. Anyone thinking of spending up to £1000 on a mid-range telescope and eyepiece set should certainly consider this as an option.

      MM4 77 GA ED/45 with SDLv2 Eyepiece - Paul Brewster

      25 July 2019

      I chose an overcast day in order to test the light gathering quality of this scope in less than ideal conditions. The first test was at 18x magnification, and the image obtained was stunning; bright and sharp with no discernible reduction in quality towards the edge of the field of view.

      MM4 77 GA ED/45 - Lee Thickett

      10 July 2019

      So, how to sum up the MM4 77mm? It is compact and lightweight for a 77mm and handles really nicely, being balanced on the tripod, and having well-engineered fast and slow focus modes. The two eyepieces make excellent companions for each other and the only thing on my wish list is a bit more field of view for the zoom. But really, this is a very nice set and well worth auditioning.

      I had a great couple of weeks using the ‘77’ in Mull. Opticron have taken the tried & tested MM4 formula, tweaked it and produced a fabulous, lightweight all-round birding scope. At no point did I regret not having my (considerably more expensive) 85mm scope instead.
