Remarks:
Since 2020 on the market is the small Pentax VD 4×20, which offers a number of special features. Beside being a fully multi-coated low magnification pocket binocular with good optics (including phase coating) and mechanics, the detachable construction offers the possibility to separate the two tubes in a single motion and to use them individually as two 4×20 monoculars. Moreover, the two separated tubes can also be connected “head on tail” which results in a small 16×20 telescope. {{ to be updated }}
